Have been looking to replace an old “single” size foam mattress topper for my guest room full size bed, and this one certainly meets my expectation - and more! I love the attractive textured, zippered cover with the heavy duty straps that can be machine washed when needed. Although I only laid on it for a few minutes, it seems extremely comfy - it “might be” a tad soft, but I will have to sleep on it to give a fair opinion on that aspect. I love the extra height that the 4” topper adds to the bed overall. I will say that it technically doesn’t “feel” like gel as much as it feels like foam, but that definitely doesn’t take away from the added comfort or the additional height for me. I would recommend this topper to anyone looking for a really nice covered mattress topper that both looks and feels VERY luxurious! (Bed frame & mattress also WAYFAIR … the best place EVER for all our home shopping needs)!
