Bests & Worsts Reviews from Amazon

So after seeing this deal posted on another site, I jumped on the California King. I'm a 165 lb. active male who does strain his back every once and awhile. The last mattress, although comfortable, didn't help the tension I had in my lower back. So here's my review (1 being the worst, 5 being the best). COMFORT - 5 out of 5: I was a bit scared at first since this was my first memory foam mattress. I like to sleep cold and on a firm mattress, both of which memory foam doesn't highlight. I was extremely surprised that that wasn't the case for me. The mattress does warm up to your body, but not to an uncomfortable temperature. Likewise, I was surprised how firm the mattress was. It was much firmer than my spring mattress which I thought was semi-firm. If you like a firm mattress, this mattress might be a good option. QUALITY - 5 out of 5: The mattress' box was torn up when it arrived. I don't blame the UPS guy since it was nearly 70 lbs, but the mattress was in good condition. The cover was soft and the foam reacts like one would imagine it would. Aside from the box, the mattress was rolled up in layers of plastic and well protected. It also comes with a 20 year guarantee. I'm not really sure how many of us really will use a mattress warranty, but I doubt it's an easy process being that it's a mattress. Shipping this thing anywhere would cost you a price of a new mattress. Maybe they cover shipping? SMELL - 4 out of 5: I've read lots of articles online about a terrible smell and odor once it's open, but it really wasn't that terrible. It wasn't like I couldn't sleep on it. It smelled new more than anything. But I did take off 1-rating here just because this is a personal preference. Some might have sensitive noses, others not so much. So if you do have a sensitive nose, consider waiting a day before sleeping on it. The smell isn't unbearable at all, just artificial. PAIN RELIEF - 5 out of 5 (for now): It was comfortable and my lower back felt like it was well-at-ease during the night - something my old mattress did not do. I'm not really one of those people who believes that memory foam can cure aches and pains, but we'll see down the road. At this very moment, I like the pressure on my lower back. OVERALL - 5 out of 5: Honestly, this is the best mattress I've slept on. It's firm, contours to my lower back, and is overall comfortable. I'm very content with the mattress, especially for the price. SET UP: I wanted to get a folding bed frame but couldn't deal with the issue of squeaking. So I built my own platform frame for this mattress out of hardwood. The mattress is laying across 6 wood planks and I cannot feel the planks at all. No squeaking as of now. Hope this helps someone!
