When I saw the big name memory foam beds appear years ago, I thought to myself, "Why so expensive? It's FOAM!". I did realize that it was a high-tech foam, but foam nonetheless. So when our 17 year old Stearns and Foster spring behemoth started sagging recently, my wife and I were pleased to find many manufacturers of memory foam beds at realistic prices. We chose this one based on reviews, price and warranty. Now here's my review in two words: BUY IT! It came rolled up, totally vacuum sealed and started expanding slowly as soon as we unwrapped it. It had a "new material" odor for a few hours, but 7 hours later it was fully expanded and once we put bedding on it, we could hardly notice smell. We put it on our Stears and Foster box spring and slept on it that night. 3 days later smell was gone. We've slept great from day 1, but my wife wanted the pillow top fluffitness that we had on old bed, so we put a thick pillow top pad (Overstock Item#: 11446847) on this and, I gotta say, with or without the pillow pad, this bed is the most comfortable bed I've ever slept on! It's the perfect balance between firm and soft, and if you want it softer, just do the pad like we did. I'm 48, 6'2" 250lbs and paint houses for a living. If I get a sore back or shoulder, I need it healed in the morning. I've NEVER had an achy ANYTHING in the morning since we've had this bed! This mattress has a 20 year warranty. Within the first 10 years, if the mattress sustains a 3/4" or deeper impression, they will repair or replace at no charge. Most other mfgrs require 1-1/2"! If problems occur between 10-20 years, there's a pro-rated charge. So take it from a couple coming off a high end spring mattress to this bed and have zero regrets, BUY IT!
