Surface integrity lost in less than 7 months, also too Hot!

Having purchased this mattress for medical reasons, I wish I had bought a real tempurpedic. The bed lost it's comfort and quality within 8 weeks of delivery. The surface was also "HOT" until it was winter outside.Sealy won't honor warranty on a defective bed and now the bed is triggering chronic neuropathy pain daily. A real bummer after surviving cancer twice to spend $2,000 on a mattress that has become an expensive torture device! Don't Buy this "wannabe bed"!!!! "Warning Will Robinson, Warning!"
