It definitely makes a nest...

Was so looking forward to this bed, did a ton of research and it came down to this or the Wink bed. We were sleeping on a Therapedic (knock off of Tempurpedic) and that bed was awful, hot, sagged, not even remotely worth the cost. This mattress looked like it was going to be perfect, we could choose the firmness, was supposed to sleep a little cooler and be a good investment. Plus they offered a 100 day sleep test. When it arrived we unwrapped it, let it open up and breath. It was pretty stinky for about a month. It slept nice for awhile, still relatively hot, but that was manageable since the firmness was darn near perfect for me and my back was feeling tremendously improved over the old mattress. Now here we are not quite a year later (just shy of 11 months today), the side where my husband sleeps is completely collapsed (he weighs 190 lbs.), so just like a nest, not at all what we were hoping for. My side seems to be ok so far, though I will say that you can't get too close to the edge or the mattress sags and rolls you off. Hopefully we'll be able to move soon and upgrade to a new mattress again. If this one had been a couple hundred it might have been ok, but for $1000 I would have expected at least 5 years out of it.
