Justin Pounds: An Interactive Career

By James Florence, Diamond Certified Resource Reporter

SANTA ROSA — If there’s one thing Justin Pounds has learned during his 16 years in mattress sales, it’s the nuances of human interaction. “Whether or not you’re a ‘people person,’ when your job entails being around and interacting with people every day, you pick up on a lot of things,” he explains. “As a result, when you interact with people outside of work, you’re able to read into body language and psychology more than the average person. So, it’s kind of an interesting skill that I’ve developed during the course of my career.”

As manager of Sleep City Mattress Centers – Santa Rosa East, Justin says his favorite part of his job is the challenges. “One interesting aspect of being in sales is that every customer has a different personality and communication style. It’s always challenging to meet people where they’re at and remove any barriers to communication. I enjoy that—it keeps me sharp and focused rather than just going through the motions.”

A resident of Santa Rosa, Justin spends his time outside of work on a variety of pastimes. “I have a 12-year-old son, so I enjoy hanging out with him as much as I can,” he details. “Other than that, I like spending time with friends, going out to eat and relaxing at home.”

In regard to his professional career, Justin espouses the importance of honesty. “I try to be honest and upfront with every customer and help them find a mattress that’s going to improve their lives,” he affirms. “A bed is probably the most underrated home furnishing. It’s not something you’re going to show off, like a couch, and it’s not as exciting as a new TV, but you spend one-third of your life on your bed, so it’s something you need to invest in. It’s always rewarding to help a customer find a mattress that meets their needs, especially when they give me positive feedback after the fact.”

Ask Me Anything!

Q: Are you an early bird or a night owl?

A: I’m an early bird.

Q: What’s your favorite type of food?

A: Mexican food.

Q: What’s your favorite TV show?

A: My current favorite show is “Yellowstone,” but my all-time favorite would have to be “Breaking Bad.”

Q: What’s your favorite sports team?

A: The San Francisco 49ers.

Q: If you could travel anywhere in the world, where would you go?

A: Fiji. I like vacationing in warm places.

Know What You Want
Gearing Up to Shop for New Mattresses in Sonoma County

As you shop in Santa Rosa, Petaluma, Windsor, Sebastopol, Cotati, or Rohnert Park or Salmon Creek, you can avoid being overwhelmed if you just think about what you are actually looking for.

Some considerations may be: Do you want a certain kind of mattress or do you want to try several kinds? What room are you putting the mattress in? Is the mattress for your or your kids? Or are you furnishing a guest room? A guest room with infrequent use may not require the same kind of mattress that you would select when buying a mattress for yourself or your kids.

To help you narrow your search, below is a list of questions to consider:

  • Do I want a Diamond Certified company that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  • Are new mattresses going to be deeper than my current mattress? Will this affect my bedding? Make it harder to get into or out of bed?
  • Do I have any health concerns – asthma, allergies, back problems – that I want to be sure to address?
  • Do I want to change the size of the mattress?
  • Is partner disturbance a concern? Am I trying to minimize motion for someone else?
  • What kind of base do I use for my current bed? Do I want to get the same kind again or a different type?
  • Do I have a specific size bed that I am replacing?
  • Are there specific issues that I want to be sure to take care of – for example, did my bed start sagging from the edge so that I need a strong edge-support system?
  • How far off the ground is my current mattress?
  • What are the dimensions of the room – can I fit the size mattress that I want to get?
  • Do I know whether I want an innerspring, a foam mattress, or a particular kind of foam mattress? Or do I want to try all kinds of mattresses?
  • Is the bed just for me or I am sharing with someone?
  • Am I looking for natural or organic options for my mattress?

What To Ask In Person
Going to See Your Your Sonoma County Mattress Vendor in Person

After the phone screen comes the part where you actually trek to Santa Rosa, Petaluma, Windsor, Healdsburg, Rohnert Park, or wherever your hunt takes you in Sonoma County. You’ll be looking for a mattress salesperson who’s knowledgeable without giving you the hard sell. Be sure to wear comfortable clothing and shoes. Go with your partner if you’ll be sharing the mattress.

You should feel free to haggle over mattress prices, as mattresses are very marked up. Sales often start at 50% off the original price. Mattress stores also often run sales, so don’t feel pressured to buy a new mattress immediately. A good negotiating technique is to have a competing price from another vendor. Be aware that there are a few mattress stores that offer low prices everyday, although most don’t. You may want to have a list of questions prepared to guide the conversation.

Here are some questions you may want to bring along:

  • Do you offer a trial period for this mattress so I can test it at home? If so, what are the details if I decide to return it? (delivery costs, shipping costs, refund or exchange?)
  • Is there a time limit on how long I can test the mattress in store? (You need at the very least 15 minutes, and half an hour is better.)
  • Are you having any mattress sales?
  • What are the different layers (if any) in this particular mattress? (how many, what fabrics, etc.)
  • Is this mattress hand-tufted? (individual layers stitched separately)
  • What are the specific details of the warranty on this mattress
  • What are the details of delivery? Will you take away my existing mattress and box spring?
  • What kind of base is this mattress on? When was the base changed?
  • Can I see how this mattress looks on the inside?

  • What To Ask References
    Questions for References of Mattress Stores in Sonoma County

    It’s best to choose a Diamond Certified mattress vendor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a mattress vendor in Sonoma County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews.That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified mattress vendor within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your mattress vendor. Keep in mind, though, that references provided to you by the mattress vendors are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    • Were the Sonoma County mattress store employees helpful in getting you the right mattress for your needs?
    • Did you like your new mattress right away or did it take time to get used to it?
    • Did you change your type of mattress, i.e. from innerspring to memory foam? Did the salesperson help you make this choice?
    • Are you using mattress pads, for example a latex pad, or a plush pillow pad?
    • Did you use a testing period? If you returned the mattress, did that process go smoothly? Did you have to pay for to return the mattress?
    • Did you choose a new mattress of the type that interests me (innerspring mattress, memory foam mattress, latex foam mattresses)?
    • Were you pleased overall with the sales process? Did you feel pressured? Did you find the salespeople informative?
    • Do you think your mattress was worth what you paid for it?
    • Are you experiencing any weird smells with your mattress? How long does it take for them to go away?
    • Did you feel pressure to cut your mattress test short? Or were you allowed to test the bed for a reasonable time? (At least 15 minutes, with 30 being better.)

  • Review Your Options

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    When deciding on the best new mattresses in Sonoma County for you, it’s important to consider the following questions before making an agreement with a local mattress center.

    • Is the mattress shop committed to getting you the most comfortable mattress for your use without undue pressure to buy an expensive mattress?
    • Does the mattress sales staff respect your budget?
    • Is the mattress vendor focused on helping you feel comfortable on your mattress?
    • Does the mattress store offer new mattresses with warranties?
    • Are the mattress store employees knowledgeable about the mattresses offered for sale?
    • Does the mattress store you’re considering purchasing from offer a testing period and clear details on how to return a mattress with which you are unhappy?

  • How To Work With
    Finding Common Ground at the Best Mattress Stores in Sonoma County

    Start by looking for clean and bright mattress showrooms in Sonoma County with professional, courteous, and knowledgeable sales staff, whether you are looking in Santa Rosa, Petaluma, Sonoma, Windsor, Rohnert Park or your area.

    You deserve to find a mattress store where you will feel comfortable spending some time lying around on the beds and researching your options.

    A good mattress salesperson will ask if you have a partner and recommend that you both test together. You’ll want to spend at least fifteen minutes and up to half an hour testing the bed. Some vendors specialize in only one type of mattress, while others offer many types. If you want to experiment with different mattress types, try to find a showroom with enough different types so you can make a side-by-side comparison.

    Find sales staff who can talk about the different materials used the mattress and who can describe the cross-section of the mattress. Only buy from a store that can clearly outline warranties, test periods, and return policies.

    If a mattress doesn’t work out for you at one store, don’t automatically give up on that mattress type. This is particularly true if you are new to the type of mattress you are trying. Visit different stores and try other samples from other manufacturers. You may not like a memory foam mattress from one vendor, but you may love a memory foam mattress from a different vendor.

    It is worth the trouble to test in different stores because stores may have more or less frequently tested beds, which can affect your experience.

    Department stores and independent mattress stores do not sell medical products. Take any marketing claims about “orthopedic” or “chiropractic” benefits with a grain of salt. If you have health concerns, talk with your doctor for recommendations before you shop

    How to Work With Your Mattress Vendor in Sonoma County
    By doing a little advance work, you can greatly simplify your quest for a new mattress.

    Think about what you are looking for. If you want to change the size of your mattress, measure the dimensions of the room so you know what will fit. Or do you just want to replace a mattress of the same size?

    Wear comfortable clothing since a good sales person will expect you to try out the mattresses. They should also know to leave you alone for a bit while you test. Bring your partner along if you expect to share your bed with him or her – this will save on multiple trips, and you can’t tell if a bed will suit you both unless you are both in it – there are space considerations along with everything else.

    If you are worried about getting in and out of bed, measure how far your current mattress is off the ground and compare it to the new mattresses you’re considering. Take note of how easily you can get into and out of the sample beds.

    Check what foundations you use on your bed at home (a box spring, a solid base, no box spring or another mattress base) and consider whether you are interested in changing foundation types. Pay attention to which foundations are being used for the sample beds so you know you are comparing apples to apples.

    Mattress names vary from store to store, so if you want to comparison shop, bring the specifications. A good salesperson will be able to match the specifications to a mattress his or her store carries even if the brand names differ.

    You may have fallen in love with a bed you used in a hotel. If you are interested, you can go to the hotel to test out the bed again. Manufacturers often make these hotel beds available to the public.

    Or, if you know a friend owns a mattress you want to try, consider testing it out during a sleepover. Such tactics will help reduce time spent in the mattress store.

    Don’t look for medical solutions in the mattress or department store. A mattress store may be able to recommend some products that can help with certain conditions – for example, a mattress cover to help keep allergens down. However, if you truly need a medical mattress or bed, you won’t find them in a department store or mattress store.

  • Be a Good Customer
    Easy Ways You Be a Good Mattress Store Customer

    It’s the mattress vendor’s responsibility to supply a quality mattress. But you play a big part in the success of your mattress, too.

    Here are a few simple steps you can take to be a good customer when purchasing a new bed from a Sonoma County mattress store.

    • Be clear and upfront with the mattress store staff. Let them know what you want from your mattress, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.
    • Remember, a friendly smile goes a long way.
    • Before you work with a mattress vendor in Sonoma County, restate your expectations and goals, and reiterate to the mattress representative your understanding of the agreement. Most problems with local mattress vendors occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • Be sure your service representative has a phone number where they can reach you at all times while they’re working with you on choosing a mattress. The work will move along more smoothly if your mattress vendor can reach you for any necessary updates or questions.
    • When your vendor contacts you, return calls promptly to keep the mattress delivery on schedule.
    • Pay for your new mattress promptly.

    Why would you want to be a good customer? Mattress vendors in Sonoma County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Written Warranties
It’s Important to Read the Warranty on Your New Mattress

Mattress warranties have some clauses and conditions that might surprise you, so take the time to understand them. Ask for a written copy, and ask questions if you need to. Some warranties will not be honored if the mattress has condition problems – for example, if it has stains, it may not be accepted back.

Often the person judging whether your mattress qualifies or not will be the person picking it up. Many warranties will cover manufacturing defects only, not normal wear and tear. Some mattress warranties prorate a refund or credit over time. So, if you return your mattress immediately, you might get the full value, while if you return it in five years, you might only get 10% of the value. Be sure you know whether your warranty gives you a refund or if you can only exchange a mattress for another one.

A test period can be a very good thing, but know how to exit from one, especially if you want to give the mattress back. Don’t rush your test period. It can take time to get used to a new mattress, especially if it’s a new type for you. It’s not unusual to dislike a mattress for the majority of the test period, then suddenly like it for the remainder of the test period, so do take advantage of all the time you are allowed.

No matter how you buy your new bed, know what you have to do to return the mattress after the test period in the case that you are unhappy with it. At the end of the testing period, can you get a refund, or do you have to select another mattress? Is there a mattress condition clause – what if it gets stained or otherwise damaged? What delivery or shipping costs do you have to pay to exchange the mattress?

Protect yourself by getting your sales person to include the word “new” on your mattress invoice. This can help if you have a warranty claim. Likewise, check that the “Do Not Remove” tag is still on your mattress. The instruction not to remove is aimed at the vendor, not the consumer. Still, it’s a good idea for you not to remove the tag anyway, since you will need information from it if you ever have to make a warranty claim.

Popular Types of New Mattresses

There are a few reasons why you need a new mattress – most often, your body will let you know. In some cases, you may also want to change the type of mattress you use.

You know you need a new mattress when you are not able to find a comfortable position, when your mattress sags, or when you fall into a valley worn out over time. If you are tossing and turning in your sleep, or when your back or neck ache after sleep, you know it’s time to consider a new mattress. A change in your lifestyle or age or health condition may also make you want to invest in a new mattress.

Frequently Asked Questions
FAQs for Local Mattress Stores

Q: Why choose a Diamond Certified mattress store?
A: Diamond Certified helps you choose a mattress with confidence by offering a list of top rated local companies that have passed the country’s most in-depth rating process. Only mattress vendors rated Highest in Quality and Helpful Expertise® earn the prestigious Diamond Certified award. Most mattress stores can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee, so you’ll feel confident choosing a Diamond Certified mattress vendor.

Q: What type of new mattress should I buy for my kids?
A: When you look for a mattress for your children, pay the same kind of attention you would pay for a mattress for your own use. As kids grow, their bones need the support provided by a good mattress. For this reason, it’s not a good idea to pass on an old mattress to your children. By the time you pass it on, most of the support is probably already gone.

Q: When do I need a new mattress?
A: There are several things to consider when wondering if you need a new mattress. In the first instance, you might know you need a mattress because you are uncomfortable – there are sags or lumps or valleys that make it hard to get restful sleep. You might wake up sore or more tired than when you went to bed. If you don’t have a known reason for tossing and turning – for example, worries keeping you awake, it could well mean that your bed is preventing you from getting a good night’s sleep.

You can also ask yourself if you are making changes to your lifestyle that would make a new mattress a good idea. Has your body or health changed in any way that would make a new mattress beneficial?

Manufacturers recommend that you change your mattress at least every 10-13 years and sometimes more often, like 7-8 years for innerspring mattresses. Memory foam and latex foam mattresses can last up to 20 years.

Q: I want to be environmentally friendly; what are my options when it comes to eco-friendly mattresses?
A: There are some new mattress manufacturers who focus on environmentally-friendly mattresses. These green mattresses can usually biodegrade. There is no standard yet for organic mattresses, though some have been proposed. In general, green mattresses use natural materials, which may be organic. Cotton, latex, and wool are commonly used. If you are looking for natural or organic materials, make sure they are not treated with chemicals. Sometimes chemicals are used for fire-resistance.

Q: Can I buy a used mattress?
A: In California, the sale of reused mattresses is regulated. You can buy one, but the Bureau of Electronic and Appliance Repair, Home Furnishings and Thermal Insulation (BHFTI) sets standards for how used mattresses must be cleaned before they can be resold. This cleaning is vital to stop the spread of diseases and pests like bedbugs. A reconditioned mattress carries a sanitation seal in California, and you should not buy a used mattress if it does not.

Q: Is it possible to purchase a new mattress online?
A: There are some stores that only sell mattresses online. In this case, you should ask for a test period. The period will allow you to have the mattress in your home for the specified period of time to see if you like it.

Be sure that you understand all the details about the test period. When will the mattress be delivered? Will your current mattress be taken away? What are the delivery costs? If you decide not to keep the mattress, what are the conditions for return? Does the mattress have to be in a certain state – what if it got dirty? Who pays the return shipping? How do you get the mattress collected?

If at all possible, test a mattress in person, then you can note down the specifications of one you like and look for something similar online.

Q: Should I worry about chemicals in my new mattress?
A: Some chemicals are used in mattresses, in large part to increase fire resistance. In 2005, California passed a law that says mattresses must withstand an open flame of 2,000 degrees for 70 seconds. The requirement was later promulgated on a national level.

To meet the requirement, mattresses use many chemicals, and the manufacturers do not have to put the information on the label. They may even decline to tell you what chemicals they use; one manufacturer was quoted as saying they didn’t want their recipe known. Be wary of organic mattresses that claim they use wool instead to meet the requirements, since wool burns at 600 degrees.

To control the chemicals present on your mattress, use a mattress cover and possibly a mattress pad to put protection between you and the mattress surface. With a prescription, you can get a mattress that does not have the fire-resistant chemicals. Some companies make mattresses and place the fire retardants in a removable barrier.

Q: What are foundations, when it comes to beds and mattresses?
A: Foundations are the support on which your bed rests. For innerspring mattresses, box springs are a common support. A box spring is a wooden frame that may include springs to help support the mattress’s load. Typically, innersprings and box springs are sold in sets. Sometimes you can replace a more expensive box spring with a lower cost box spring from the same manufacturer.

Be sure to check to see whether your warranty is voided if you do not buy a new box spring at the same time you buy the mattress – some manufacturers require the pair be purchased to maintain the warranty. In any case, do not use old, sagging box springs with a new mattress, as they will not offer the proper support.

Innersprings can also rest on fixed or flexible slats. Slats tend to last the lifetime of the bed, but if they do sag, they need to be replaced. Slats are often used with foam mattresses, whether latex foam or memory foam.

Q: Is that really a good deal for a new mattress?
A: Mattresses often have really big markups. You should not be surprised to find discounts of 50% off a manufacturer’s price. And you should not feel shy about haggling to get more off if you can. Also be aware that sales happen often – it’s rarely a once-in-a-lifetime opportunity. Even if no sale is on, you can still haggle on the price.  There are a few mattress stores in Sonoma County that offer discount prices every day, and they may be less open to haggling.

Q: What type of mattress is best?
A: The answer to this is simple. The best mattress is the one that gives you and your sleeping partner, if you have one, the best comfort. This includes the right amount of support and enough space.

The best way to determine the best mattress is to try them out in the store. Plan to spend a good amount of time – at least fifteen minutes and better if you can get thirty minutes. Test with the person you sleep with and look for things like good back support, no aching body parts from hard mattresses, enough softness to keep you comfortable, not too much heat production, and the ability to move easily, including getting in and out of the bed.
