  • Form mattress
Size: Full Style: 12 Inch
Love the thickness, firmness and soft quality of the texture of the bed. I do believe it worth every penny I paid, I have slept very well of the last couple of nights. Very simple set up. Take it out, place on frame and open it.

  • Stylish & Supportive
Size: Queen Style: 12 Inch
We upgraded from a cheap 10 inch mattress and WOW. This 12 inch Queen not only looks luxurious in our downtown apartment but the reinforced perimeter means we use the entire surface. His 3AM tosses don't travel across the coils. The cooling cover is a bonus for warm nights. Perfect blend of design and function for professionals. ... show more

  • Built to Last Years
Size: King Style: 14 Inch
Y'all, this King is a BEAST. The individually wrapped coils handle our combined like champions – zero sag after 6 months. Edge support is rock-solid; I can sit on the side without collapse. Motion isolation is impressive too; my wife doesn't feel my 5AM wakeups. Best investment for bigger folks seeking quality sleep. ... show more

  • Finally, Undisturbed Sleep
Size: Queen Style: 12 Inch
My partner works night shifts and often comes to bed at 2AM. Thanks to the advanced motion isolation in this 12-inch Queen, I literally don't feel a thing. The edge support is also a game-changer – we can both sit on the side to put on shoes without roll-off. The zoned support cradles my hips perfectly (side sleeper here!). Worth every penny for urban couples. ... show more

  • No More Sagging!
Size: King Style: 14 Inch
After 2 years, our previous mattress had permanent dips. This 14 inch King's reinforced perimeter and high-density coils provide incredible load stability (we're both over 200lbs). No more rolling toward the middle! The durable construction feels solid, and the motion isolation means no more waking each other. Finally, a mattress that supports us properly. ... show more
