This product arrived timely and well packaged. The price was reasonable and the foam itself is very firm, which is what I expected. But the stated dimensions were not accurate. The ad states, "Queen size measures 60 by 80 by 5 inches". The 60 and 5 were correct, but the length was 80 at one corner and tapered down to 77 inches at the other corner...not quite a rectangle that most people would expect for a bed. This is awful quality control! This worked ok for me as I needed to cut it down for a non-standard full bed, but for those of you who really need the stated size; BEWARE!!!

I bought this assuming that it would be firm mattress pad and would help my back. Initially when I got this, i was really happy. The topper was realy firm and was good support to my back but as I have used it over last few months, i feel the topper has lost it firmness.

This goes only for the 5" thick version of this - AND IT WAS 5" (Haven't tried any of the other thicknesses)
I chose this to review for my first Amazon review (long-time customer) because I'm so enthusiastic about this chunk 'o foam!

If you're a tall, big man with back troubles like me - don't listen to the namby pamby's who gave it 1 star.
I got it, and like one of the 4 star reviewers, you just wait a couple of days without putting any load on it or sniffing at it,
and you'll have a REAL NICE, FIRM, back-relieving mattress! Follow instructions-
Don't use a razor knife to open it- foam will bias on you.

The CUT of the mattress wasn't bad, and the size is a GENEROUS QUEEN I ordered - seemed waaay too small first, now it's almost too big.
The smell certainly WASN'T like cat pee, more woody than pee-like (after airing out)
NOW I put a couple of 3" hard pink foam boards underneath and zipped it up into a zippered queen BOX SPRING cover... Read more
