All overpriced china made mattreses are a POS.My Oklhoma made mattress was $600 and I still love it 15 years later.We bought the highest end Serta iComfort and it was amazing for about 3 years. Then the foam seemed to suddenly lose all of its resiliency. Went from firm and supportive to like sleeping in a hammock almost overnight. But since without any weight on it, it will spring back to its normal height, there is no sag, and hence no warranty coverage. Tempurpedic is the only foam mattress I would buy at this point. We have foam hybrids right now that are great but as soon as they go south, I’m getting a Tempurpedic Breeze. They are $3800 each for twin XL.
$3800? Holy cripes! I'd never pay that for a pile of china shcit.
