Great purchase for college dorm

JessJanuary 12, 2026

I am absolute in love with this mattress topper. It fits perfectly with the dorm twin XL bed and the thickness really provide all the support you need for a good night of sleep. The mattress is very stable and firm in shape and came with a nice, no smell packaging with warranty assurance. It’s great value for what you have to pay. I have a mattress topper so I haven’t really experienced the cooking aspect yet, but the product has a great overall functionality. Would totally recommend! Read more

Extremely comfortable

JunebugDecember 19, 2025

Wonderful addition to my hard mattress! Not too soft, and no longer too hard, has helped w/ back pain Read more

Very comfortable and warm

J. SwensonDecember 29, 2025

This is way more comfortable to sleep on than my mattress. It has helped me with lower back pain and hip pain. I find it to be warmer than my memory foam mattress. In the winter that has been nice. It warms up almost instantly when I lay down. I'm not sure if it will be too warm in the summer. Read more

Softer sleep!

GA girlJanuary 1, 2026

The topper came promptly and was compressed into a box. After removing the plastic wrap, it expanded to full size in no time. There was a slight smell but I let it air out for a couple of days before using and the smell dissipates fairly quickly. It really molds to your body and I have had much better sleep. My back and shoulders are more comfortable at night. Would recommend! Read more

Perfect for college dorm

AngelaJanuary 5, 2026

This was the perfect addition to my son's college dorm bed. It provides that extra padding that is needed on a thin mattress. Very durable! Read more

Falling apart right out of the box.

JCOctober 19, 2025

I ordered 2 twin xl mattress pads. Opened them last night to plump up. Put one on a bed, laid the other on the bed only to discover it is coming apart. Big tears. No way to fit it in a box now that has fully plumped up so I guess I am stuck with a pad I cannot use. I love Amazon Prime for its easy returns but now I have to find a box big enough to return it or trash it. Read more

Just as advertised! Really comfortable!

CustomerDecember 7, 2025

We ordered a 2 and 3 inch version of this mattress topper because we’d ordered a previous one and really liked it. These are as advertised and are very comfortable. We returned this topper because we were setting up a medical bed for Mom. We wanted it to be soft but not too soft! The 2 inch arrived first and was placed on the bed—it was just what Mom needed! We did return the 3 inch because we were afraid that it would be too difficult for her to get out of bed with more padding since she’s having difficulty moving when in bed. Read more
