If you are looking for the very best in luxury, comfort, support and durability, this pillow top mattress—the flagship of our line—is for you. We take our best continuous coil, ComfortFlex Innerspring support system, and add our exclusive all steel side support system. We top the unique support system with a double layer of insulators to prevent the softer cushion materials from wearing their way into the springs. This will give you a longer-lasting, more durable mattress. We then place a very high-density topper pad over the insulators, and close this up with a quilted inner panel to secure everything for a strong, comfortable mattress.

This mattress is the plushest mattress in our lineup and features a 4” pillow top with layers of plush 4.0# density Latex and layers of ultra plush 2.4# high-density polyurethane. This combination gives you the ultimate in pressure relief. There is simply no other mattress that compares. We finish this exquisite mattress with more high-density, high-quality foams quilted to a luxurious cover that will invite you to a great night's sleep. More information here.

Sumptuous quilting and padding layers, including pure latex, make the Kingsbury our softest and most luxurious mattress. Comfort is a key ingredient in a good night's sleep. Settling in to the plush pillowtop, you'll meet the slight bouyancy of pure latex with even distribution of pressure to prevent pain in parts of the body where peak pressure can occur (shoulders, hips, heels) and guarantees good blood circulation. Latex offers excellent temperature regulation (not too warm, not too cold) and moisture control (evaporation of perspiration) perfectly tailored to the sleeper.

Our ComfortFlex unit utilizes the latest technology in high tensile strenghth wire, so that weight and pressure is passed off to as many coils as needed. This means our unit adjusts to each sleeper, giving individualized comfort and support. Support is the next ingredient in healthy sleep. Your muscles and tissues rejuvenate when you remain in deep, restorative sleep, which happens when your body is properly supported. Comfort gets you to sleep, support keeps you there.

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.
