  • The world's best firm mattress.
Size: Queen Style: 12'' Luxe
This is a very firm mattress but also very, very comfortable. I love it! My 140 lb dog jumps up and I barely know it. It is incredibly supportive and everything I wanted in a firm mattress. It came in 2 days, took less than 24 hours to fully expand, although I waited the whole 24, and I've been sleeping blissfully every after. ... show more

  • Fast shipping, great night’s sleep
Size: King Style: 14'' Ultra
Ordered the afternoon of the 25th, was delivered the next day despite being three states away. The directions said to let it air out for three days, which we did. I’ve slept on it the past two nights and it was wonderful. I’m middle aged so I need firm support but it’s soft enough that you wake up feeling refreshed and not achey. Husband enjoys so far as well. ... show more

  • Excellent mattress for the money
Size: Queen Style: 12'' Luxe
I have severe spine problems and needed a new mattress. I have owned a Temperpedic, Serta, and other name brands, but this is the best of all. I have slept through the night since I got it, and I haven’t done not been able to do that in a couple years.
