My mattress is old, and there was a spring sticking in my back no matter which way I flipped it. Rather than get a new mattress, I thought I would give this 2" mattress topper a try. I couldn't be happier! I have it for about 1 week now, and my sleep has greatly improved. I am a side sleeper, but I do not sink all the way into it because it is 4 lb density, and can't feel anymore springs! I was initially looking for something "rock hard" that I would not sink into at all, because I normally like a firm mattress. This topper is definitely not rock hard, there is some give to it. However, I find that that just makes it more supportive, without any pressure points. I've read reviews from other people complaining that they cannot roll over because the topper has too much give, and they get "stuck." I have not had that issue with this topper. It is dense enough that moving is not an issue. I must note again that I have the 2" topper. This company also carries 3" and 4", which may have... Read more

I'm happy that I paged through 4 pages of memory foam toppers to get to this one.
Product arrived two days after order. Shipping was free, and price was much better
than others. Queen 2" 4 lb/cu ft. topper weighed approx. 21 pounds, exactly what it should weigh. It had some smell, which wasn't too bad. I aired it out for 3 hours on my terrace, then put it in my bedroom. I noticed a little odor the first night but it wasn't objectionable. I didn't notice any odor until I trimmed the topper to fit my full sized bed, a few weeks later, which released a little odor. After that no odor issues. This thickness/density works well for me. I don't sink in so deep as to feel my hard bed underneath. And since I'm not burrowed in too deep, the topper doesn't feel hot. (I'm a male, 6'1" and 170 lbs.) Yet the pressure/pain in my hips is completely gone.

Great. I'm deployed in Kuwait. Mattresses are not the best here. This is the difference between waking up every hour, or getting a good nights sleep.
You don't want to go over 2 inch depth. Would never get your fitted sheet on the bed.
As far as the smell when new, dissipates very quickly. Not strong, at least for me. Air it out for a couple of hours should take care of it.
