Very Comfortable and Thick!

[This review was collected as part of a promotion.] I'm really happy with this 4-inch memory foam mattress topper. It arrived compressed, but after opening it and letting it expand, it reached a nice thickness and looked even all around. The foam feels soft and supportive and adds a lot of cushioning to the mattress. I especially like how thick it is—it makes a firm mattress feel much more comfortable and gives the bed a plush, cozy feel. The quality looks good for the price, and mine expanded nicely without any major uneven areas. Overall, I'm very satisfied with it so far and would definitely recommend.

Great topper that provides a lot of support

[This review was collected as part of a promotion.] I am really enjoying this mattress topper! I did allow it a full day to air out and fully come to life. There is a smell, but there are instructions that state you can spray a fabric spray which I did and it helped. The four inch foam makes a huge difference. It is like sleeping on a cloud. I was able to still move around, but it conformed to my body. I slept so much better after night one. I had no issues with my sheets fitting.

Verified Purchase

Performed just as promised, great buy!

For the price paid for this mattress, I expected to give a bit of relief but I didn't expect it to transform this bed as it has. The difference it has made in my sleep comfort is priceless. It fits perfectly, it's thick enough to make a true difference,vit has no odor, and it fluffed out fully within an hour or so. I have only a minor issue and that is that after a few days, I have to place it back in the proper position as it as moved over from its desired placement. I haven't felt it move at all, but , it does slide a tiny bit over time. For the price I paid, I can deal. I have seen a few reviews saying it makes you hot or sweat, I have not found that to be an issue whatsoever. All in all, IMO, I think this memory foam mattress topper to be a great purchase that is true to the claims made. it gives a better, more comfortable rest than I had without it. I recommend this product, as I feel it was a great purchase because quality and performance wise, it does the job it says it does. Happily recommend.
