Need a very firm mattress with a lot of support but still want comfort? The Dover may be what you are looking for.  We start with our exclusive ComfortFlex continuous coil system that gives you the firmest support in the industry. We add our unique insulation package to ensure longevity of the mattress by not allowing the softer cushioning materials to sink in to the spring. Now we give you that very firm comfort level you want by putting 3 layers of very firm, high-density polyurethane cushioning in the mattress.  We don’t want this mattress to be so hard that you can’t enjoy sleeping on it so we add 2 softer layers of premium cushioning materials quilted to a very attractive cover. This mattress will give you that very firm supportive feel while still having a little softness in the initial feel. More information here.

To best take care of your mattress set, ensure its long-life and preserve your warranty rights, please follow these Do’s and Don’ts of bedding care.


  • Give your new sleep set time to “air” upon removal from its plastic packaging. A new mattress set may have a “new set smell” which will dissipate over time.
  • Properly wrap your mattress and carry it on its side when moving it.
  • Keep your bedding clean. We suggest using a protective mattress pad to avoid stains. Washing your mattress pad and vacuuming your mattress every month will help keep your set in a sanitary condition. Your warranty will be voided if the mattress is stained and/or is in an unsanitary condition.
  • Rotate your mattress to ensure even wear over the entire sleep surface. We recommend rotating your mattress at least 4 times per year.
  • Use an appropriate frame and center support for Full, Queen and King sized sets. King and Queen Sets should be supported with a bed frame that supports head, foot sides and the center  of the set with a rigid center support that has legs extending to the floor.


  • Don’t place your mattress near an open flame or expose to fire. The mattress is not flame – nor fireproof, and can ignite and/or burn if exposed to open flame or fire when ignited. Some bedding material can burn rapidly and emit smoke and hazardous gases.
  • Don’t smoke in bed. This mattress is manufactured as required by federal law to resist, but not necessarily eliminate, ignition by smoldering cigarettes.
  • Don’t let anyone stand or jump on your mattress.
  • Don’t allow your mattress to get wet. Protect it from liquids with a proper mattress pad.
  • Don’t place a board between your mattress and box spring. Your sleep set is designed specifically to provide you with proper support, and the foundation plays an important role. If you think a board will help, this could be a sign that your mattress set is wearing out.
  • Don’t bend your mattress. Flex it when going through doorways.
  • Don’t use dry cleaning fluid on the mattress or any liquid cleaning fluids. These chemicals can/will damage some of the construction materials.
