There are numerous mentions throughout this website to "major" mattress manufacturers and suggestions to avoid many of them for many reasons including their lack of transparency about the quality of the materials they use in their mattresses, the use of lower quality materials, or because they are poor value compared to many other smaller independent manufacturers who make similar mattresses with the same or better quality, are transparent about their materials and designs, and sell for better prices. This article will give you a better idea of which manufacturers are in the top 15 ranked by size, which of these to avoid, and which may be "possibilities" in terms of their transparency, quality, and relative value. compared to other larger manufacturers. Between them, these top 15 manufacturers control 92.1% of the market (2015 figures) and the top 5 of these (which are all in the AVOID group) control 76.4% of the market. This leaves several hundred smaller manufacturers that often make better quality and value mattress that don't have the budget to spend on massive advertising and that are often only available locally or regionally to share the remaining 10%.
One of the goals of this website is to help consumers identify and find the manufacturers who are open and transparent about the materials in their mattresses and are focused on making and selling higher quality and value mattresses. These top 15 (+2 additional that I've added because they were in or close to the top 15 in previous years) are also "ranked" according to the likelihood that you will be able to find out accurate information about the quality of the materials in their mattresses. AVOID: Your chances of finding out accurate or up to date details of the materials in their mattresses are not high enough to consider them or they are not good value compared to other similar mattresses. SMALL POSSIBILITY: In most cases the information about the materials in their mattresses are not available but there may be a few exceptions for some mattresses. SOME POSSIBILITY: The information about the materials in their mattresses are sometimes available and sometimes not depending on the type of mattress and/or on the licensee that makes their mattress.
GOOD POSSIBILITY: in most cases information about the quality of the materials in their mattresses are available but it will also depend on the type of mattress and/or on the licensee who makes them. 1. SERTA: Owned by private equity group (which also owns Simmons). Tends not to be Transparent. 2. SEALY: (including Bassett Bedding and Stearns & Foster). Public corporation (which also owns Tempurpedic). Tends not to be transparent. 3. SIMMONS: Owned by private equity group (which also owns Serta). Tends not to be transparent AVOID 4. TEMPURPEDIC: Public corporation (which also owns Sealy). Sometimes transparent but poor value. Transparency is being reduced or eliminated and material quality/density is concurrently being reduced. 5. SELECT COMFORT: (Airbeds). 6. CORSICANA: Private corporation. Tends not to be transparent with rare exceptions. 7. THERAPEDIC: Licensee group. Most licensee factories are transparent about the materials in their mattresses and may have better quality/value than others in the "major manufacturer" group.
8. COMFORT SOLUTIONS: (including King Koil). None of the licensees tend to be transparent with rare exceptions. 9. ENGLANDER: Licensee group. Some licensee factories are transparent about the materials in their mattresses and may have better quality/value than others in the "major manufacturer" group. 10. RESTONIC: Licensee group. 11. ASHLEY FURNITURE: Private ownership. Transparent about some of their materials but tends to use lower quality materials. 12. SYMBOL: Private corporation. Tends to be transparent about some of their mattresses and not others and may have better quality/value than the major manufacturers in this group. 13. KINGSDOWN: Private corporation. 14. E.S. KLUFT (and AIRELOOM): Private ownership. 15. SPRING AIR: Licensee group. Most licensee factories are not transparent with rare exceptions in some areas of the country. Was #15 on the previous years list. Sometimes transparent and may have better quality/value than some of the major manufacturers in this group.
ECLIPSE / EASTMAN HOUSE: Privately owned but made by a licensee group. Probably should have been ranked as #15 on the previous years list on their audited numbers. They have told me that they are transparent about all their materials and components as long as the retailer that sells them calls the factory. Beyond these top 15 (+2) manufacturers there are hundreds of smaller manufacturers that are either local or regional or in some cases national which are well worth considering if they are fully transparent about the materials they use in their mattresses. Some of these sell factory direct and some are sold wholesale through stores around the country. Many of these smaller independent manufacturers provide better quality and value for consumers but in all cases knowing the specific details of the materials and components in a mattress and making "mattress to mattress" comparisons is the only way to make meaningful comparisons. Blind purchases should always be avoided regardless of which manufacturer makes the mattress.
