  • Works great as mattress for mini sofabed
Size: Full Item Display Height: 3 Inches
Guests say the mattress is super comfortable. Wish it came in other sizes as I had to trim this to fit my needs. Use a scissor to cut. Also, would be nice if it came with a bag to store it in when not in use.

  • Extra cushion is nice!!
This memory foam bed topper added just the right amount of extra cushion to my queen-sized mattress. It bounced up nicely after opening it and fits my bed nicely. I really like it!

  • Comfy

My old topper finally died and I bought this. Very comfortable but every few days I have to pull it back on one side

  • Absolute value for money!
Finally got around to opening and setting up this topper. It takes a good 48 hours to competely fluff-up - and do not try to use it prior to that. Let it completely expand and let it air out. Ours came without any strong smells, but any smell should disippate in 2 days. The topper is really comfortable and adds an extra couple inches to the mattress. The gel infusion helps keep it cool - and so does the included holes in the topper lets the topper breathe. Working great and happy with the comfort level. ... show more

  • Comfy but a little hot
My foam mattress finally felt comfortable with this on top. I let it air out for a few days after opening and was happily surprised that it didn’t smell strongly of fumes. The only issue is that I think it holds in heat/doesn’t breathe well, so beware if you get hot at night. It fit my twin mattress well. ... show more

  • Comfortable True to Size
This Mattress Topper is sufficient and comfy. It fits over my queen mattress perfectly and stay in place. It provides a lot of heat and the material is not that breathable, but it is sure comfortable. It gets cold in the winter so I am sure it will be a gem during that time. It does its job and is great for the price. I do recommend letting it air out for a couple of days. Has a slight odor. But it goes completely away! ... show more
