I am happy with this mattress. It has it advantages and drawbacks. Info: I am 6-7 tall and 240 pounds. Mattress used for over 3 months. 1) Comfort - I came off a hybrid water bed which i liked to get a little more support. This mattress is quite firm. I weigh 240 and I still say the mattress is firm. If you are are expecting a cush mattress that you sink into this is not your mattress. 1a) This is a foam mattress that does not have some of the newer features like holes in the foam or space between foam cores. That means heat. If you have a problem with heat, especially if you live in a warm climate like I do and do not have your room set pretty cool. you might want to think hard about this purchase. 1b) If you are a back sleeper i think you will love this mattress. I sleep on my side a lot and the firmness on some nights make me wish i had my waterbed back. Once again i am 240 lbs so i do put a dent in the mattress. Maybe i will get used to this long term 2) Construction - the mattress seems well made. Even with my weight i have seen no sign that the mattress was not springing back to its original shape. This was one of my biggest fears when buying this inexpensive of a mattress. 2a) The cover of the mattress may be a long term problem for some since it is off white in color and has a fuzzy fleece like top. I think you need to make sure you use a good mattress cover and take care of it if that is an issue to you. 2) Heat again. I put a heavily padded mattress cover on the mattress to see if the heat could be tamed. I think this has helped a little but not a lot. 3) Price - The mattress is now $60 less than when i bought i and i consider it a buy at my price. If you are willing to take the risk of buying a mattress thru the net without trying it out, I dont think you can go wrong with this mattress. Things to consider. 1) heat 2) firmness 3) if you have a tall foundation that you want to put the mattress on and you are short you might want to reconsider or buy one of the new short foundations. On my waterbed foundation i sometimes feel like i am getting into a bunk bed and i am 6.7 ft tall. 4) Oh, last thing along with heat is cool. If you have the mattress in a cool room the bed is cold when you 1st get in but due to the heating of the foam you will be toasty in a few minutes.
