Know What You Want
Things to Consider As You Look for a New Mattress

You know that you have many decisions to make as you start to look for a mattress, whether you are shopping in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, or Corte Madera or Ross.

Don’t let yourself be intimidated by the long list of options, but do think about many of them seriously. Do you want a certain kind of mattress or do you want to try several kinds? Think about the rooms where you’ll be putting the mattress – are they your bedroom or are you furnishing a guest room? A guest room with infrequent use may not require the same mattress investment you may want to make for the beds your family uses every day.

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

  • Do I want a Diamond Certified mattress store that is rated best in quality and backed by the Diamond Certified Guarantee?
  • What kind of base do I use for my current bed? Do I want to get the same kind again or a different type when I buy a new mattress?
  • Is partner disturbance a concern? Am I trying to minimize motion for someone else?
  • Do I have any health concerns – asthma, allergies – that I want to be sure to address?
  • 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?
  • What is the size of bed for which I am replacing the mattress? Will I need the same size mattress, or am I changing beds as well?
  • Do I want to change the size of the mattress?
  • 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?
  • How far off the ground is my current mattress?
  • Is the bed just for me or I am sharing with someone?
  • Am I looking for natural or organic options for my new mattress?
  • What are the dimensions of the room – can I fit the size mattress that I want to get?
  • 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?

What To Ask In Person
Visiting Marin County Mattress Centers

Once you’ve decided which stores will offer you the right options to try, you can make the trek to San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, or wherever the hunt takes you in Marin County. You’ll want to test the mattresses personally.

You also will want to have a list of questions prepared so that you can guide the conversation. You’ll be looking for a mattress salesperson who’s knowledgeable about the product without pressuring you.

Be sure to wear comfortable shoes and clothing that will allow you to test the new mattresses in the stores. If you’ll be sharing the bed, take your partner with you.

Be bold – mattresses are one item where you can haggle on the price. It’s worth noting that industry insiders say that mattresses often have a very high markup. Sales often start at 50% off the original price. Stores also run frequent sales, so you should not feel that a specific sale is your last chance. One good negotiating technique is to have a competing price from another vendor.

Here are some questions you may want to bring along:

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

  • What To Ask References
    Questions for Marin County Mattress Store References

    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 Marin 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, 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 to see how their previous customers feel about the service and product they received.

    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.

    Sample questions include these:

    • Do you think your mattress was worth the price you paid for it?
    • Did you feel the sales staff were knowledgeable about the mattresses in the store's inventory?
    • Did you feel pressure to cut your test short? Or were you allowed to stay on the bed for a reasonable time? (At least 15 minutes, with 30 being better.)
    • Did you choose a mattress of the type that interests me? (These may include innerspring, memory foam and latex foam mattresses.)
    • Did you change your type of mattress when purchasing a new bed (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? Are you liking them?
    • Are you experiencing any weird smells with your mattress (plastic or foam smells, for example)? How long does it take for them to go away?
    • Were you pleased overall with the sales process? Did you feel pressured? Did you find the salespeople informative?
    • Did you like your new mattress right away or did it take time to get used to it?
    • Did you use a testing period? If you returned the mattress, did that process go smoothly? What did you have to pay for to return it?

  • How To Work With
    Searching Out the Best Mattress Vendors in Marin County

    Your search for the best mattress vendors in Marin County, whether you are looking in San Rafael, Novato, San Anselmo, Mill Valley, or Larkspur, should lead you to professional, courteous, and knowledgeable sales people.

    Look for a clean, bright showroom where you feel comfortable spending some time lying on the beds and testing your options. You’ll want to spend a minimum of fifteen minutes on your top choices to make sure they are comfortable, and a half an hour will give you an even better idea of how the mattress feels over the long-term.

    Make sure you and your partner come to the showroom to test the bed so that you're sure the mattress you choose works best for both of you.

    Look for a showroom that offers the type of mattress you want, and if you want to experiment with different mattress types, ideally a show room that offers the different types for side-by-side comparisons.

    While you don’t have to focus overmuch on the specifications, since comfort is always your first concern, you will want a showroom that can show you cross-sections of the mattress and talk about the different layers of the mattress. Only work with a store that can clearly outline warranties, test periods, and return policies.

    Try different examples from different vendors and different stores, if you are trying out a specific mattress type, especially if you are new to the kind of mattress. You may not like a memory foam mattress from one vendor, but you may like a memory foam mattress from a different vendor. It pays to test in different stores because stores may have more or less frequently tested beds, which can affect your testing experience.

    When you shop, be wary about claims that say the mattress provides “orthopedic” or “chiropractic” support. The mattresses you look at in a department store or mattress store will not be medical products, so take all such claims with a grain of salt. If you have health concerns, you may want to ask your doctor for any recommendations before you shop.

    Make it Easy to Work With Your Mattress Vendor in Marin County
    A little preparation helps keep mattress shopping manageable. Know what size mattress you want to buy. If you want to change the size of your mattress, measure your room dimensions so that the sales person can help you assess the fit of the new size. Wear comfortable clothing. A good sales person will expect you to try out the mattresses. They’ll also know how to leave you alone for a bit while you do.

    If you expect to share with a partner, bring your partner along. This will save time in the long run. Bring a measurement of how far your current mattress is off the floor, especially if you have concerns about getting into or out of bed.

    If you are shopping with the name of a specific mattress in mind, bring its specifications, too. This is because mattress names vary from store to store, but a good salesperson will be able to match the specifications to a mattress his or her store carries.

    Some manufacturers have agreements with hotels to make beds for those hotels. You can go to the hotel to test out the beds, and the same models are often available for sale to the public. You can also sleep over at a friend’s sometimes, if you want to test a certain mattress and they own it. These tactics will help reduce the time you spending testing beds in the store.

    If you have health concerns, such as allergies or asthma, or back pain, talk with your doctor about your mattress before you start shopping. Doctors may or may not be able to recommend what you should look for, depending on their experience and expertise. A mattress store may be able to recommend some products that can help with some conditions – for example, a mattress cover can help keep allergens down.

    However, if you truly need a medical mattress or bed, you will not find the best choices in a department store or mattress store. Instead, ask your health care professional to suggest medical mattresses or hospital bed suppliers you can purchase from directly.

  • Be a Good Customer
    Be A Good Customer When Buying a New Mattress

    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 hiring a Marin County mattress store.

    • Be clear and honest with the mattress vendor. Explain what you want from your new mattress, the long-term outcome you’re expecting and specific ways they can satisfy your expectations in terms of customer service and products.
    • Remember, a friendly smile goes a long way.
    • Before you purchase a new bed from a mattress center in Marin 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 the mattress promptly.

    Why would you want to be a good customer? Mattress vendors in Marin 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.

Get It in Writing from Your Marin Mattress Store

Mattress warranty conditions vary widely, so be sure to get any guarantee you’re promised in writing and that you fully understand the conditions of that guarantee.

For example, many warranties will only cover manufacturing defects, not normal wear and tear. Some mattress warranties prorate a refund 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.

Some warranties also depend on the mattress condition to be valid. In these cases, the person picking up the mattress examines the mattress and determines whether it is eligible for return – which it may not be if it has stains, visible damage or other specified problems with the condition. For this reason, you should ask if there are any specific rules about which mattresses can be returned and which cannot.

Be sure you know whether your warranty gives you a refund or if you can only exchange a mattress for another one.

When your vendor writes up the invoice for your mattress, be sure he or she includes the word “New”. This protects you from unknowingly buying a recovered/used mattress and may be of help in warranty disputes. Similarly, ensure that the “Do Not Remove” tag is intact on your mattress when you purchase it. While the tag is designed to prove that you have a new mattress, it’s a good idea for you not to remove it even after you purchase the mattress, since you will need information printed on it if you have a warranty claim.

Take full advantage of any 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 most 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. It’s especially important to take advantage of a testing period if you buy an online mattress, since you won’t be able to try it before you buy.

Find out what is required to return a mattress after a test period. Is there a mattress condition clause – what if it gets stained? Do you have to pay shipping or delivery fees? At the end of the testing period, can you get a refund, or do you have to select another mattress? What delivery or shipping costs do you have to pay to exchange the mattress?

Frequently Asked Questions
FAQ for Local Mattress Store Customers

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 who have passed the country’s most in-depth rating process. Only mattress vendors rated Highest in Quality 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.
