    • Amazingly comfortable!
Color: White Size: California King
Made our old sinking mattress feel new again. I usually do not write reviews but, this mattress topper is super comfortable. We have been thinking of replacing our expensive sinking mattress but, after we put this pad on the bed it is so comfortable that we don't even need to replace our old mattress. Slept like a baby! ... show more

    • Waterproof!

    • Very comfortable but still gives support
Color: White Size: Queen
Perfect for anyone who needs a softer bed but still need support. I have sciatica issues and this makes my bed very comfortable.

    • Wonderful mattress topper mattress pad
Color: White Size: King
We love this mattress topper & bed pad. It is so fluffy & soft. It came out of the package fluffy. We've been using it for a little over 2 months & it's stayed fluffy, not packed down from sleeping on it. The filling doesn't bunch or shift. My husband said he's sleeping better since we got it. He'd been getting pain in the hip from side sleeping even though our mattress is a high-quality memory foam & soft. This mattress topper has added another layer of cushion. It has a nice soft cover on it. It fits our king mattress perfectly. We love it & I highly recommend it....I have not laundered it yet so can't comment on that. ... show more

    • Good Enough
Color: White Size: Queen
This is pretty much what I was looking for, a pumped up mattress cover. I do wish the 2" were true. Maybe it is before you lie on it, but I doubt it. I'd still buy again. My bed was stiff as a board.

    • Best Mattress Topper!
Color: White Size: Queen
Best mattress topper! It added wonderful comfort to the bed while providing quality protection. Liked it so much, I purchased a second one for another bedroom.

    • Comfy, but not as thick as stated in the description
Color: White Size: Full
I disagree with how thick the description says this topper is, it's definitely less. However it is soft and after it's aired a bit, does provide a nice cushion. The size fit easily over the full sized bed.

    • Service is excellent always on time or days prior.

Shopping with Amazon is the way to go. Amazon has everything. If they don't have it; it hasn't been made yet! Mattress topper first great. As advertised.
