Bests & Worsts Reviews from Amazon

I purchased this King bed for $589 shipped after reading the reviews here and trying out mattresses in various local retail stores. Notes * Once opened and stretched out the mattress expanded to a about 11.5 inches within 15 hours. I still let it sit, undisturbed, for 72 hours. There are a few very shallow dips along the edges of the mattress. Nothing noticeable when the sheets are on. * It definitely has a that chemical "memory foam" gas smell. The smell is still here one month later but it is VERY faint; my partner can't smell it at all. I'm very sensitive to smells and after the first two nights it didn't bother me. * This is a FIRM mattress. I was expecting a slightly softer mattress but little did I know the firmness of the 12in Gel Swirl was something I would enjoy. * I have no clue how you would return this mattress. It's gigantic and weighs quite a bit. * 12 inches is a TALL mattress. Keep this in mind when you're buying your foundation. PROS * Feels well made. I don't get the feeling it's going to tear or wear out easily. * Responsive foam. I'm 6'2", 340 lbs, So far the foam retains its shape within seconds while still providing a comfortable, supportive sleep * Low motion transfer. I tend to move in my sleep. My partner doesn't seem to notice with this mattress. * Price. This is half the price (or less) of the retail equivalent * Warranty. Comes with an (untested) 20 year warranty. I read it over and it seems legit. * It sleeps cool. Like I said, I'm a big dude and my partner is large as well. We haven't hit summer yet but we keep the house at 70F and have had no problems with heat. CONS * Smell. It does have the chemical memory foam smell. * Dips. There's probably 6 shallow dips along the edges of the mattress. These are less than half an inch. I recommend this mattress for any first time memory foam owners who like a firm sleep. It's supportive for large folks and retains it's shape (so far). For under $600 shipped I don't think you could find a better deal. Time will tell and I will update my review in a year or if any negatives appear.
