I purchased this a few months ago to replace my other mattress topper. At 5’5’ and 125 pounds I didn’t expect it to start to pocket after a month. Very uncomfortable I am a side sleeper and wake up in the center. I’ve tried to take it off the bed and turn it in. Maybe it’ll be more comfortable, but no, it needs to be replaced with something a little bit more firm that will hold my weight. The company reached out to send me another one that was an upgrade. I never received it so everything has been returned. I won’t deal with this company again.

I'm 69 yrs. old and would toss and turn all night, trying to readjust my position to relieve the pain in both hips and both shoulders. Problem was my old, really sagging mattress. Mattresses are expensive and have a wide range of different qualities. I figured that $85.00 wasn't too much of a loss if the topper failed to perform. While the box said it was a queen size, I was dubious when I pulled out the foam part, as it appeared to be for a single bed. After unfolding it and putting it on the bed, it only took 2 hours until it expanded to its full thickness. The pillow topper comes with a full skirt that'll reach down and under the mattress and is long enough even for thicker mattresses. The edge of the skirt is elastic, so it'll stay tucked under the mattress. A common complaint I saw in reviews of other toppers, is that the foam pad was left exposed, as a skirt wasn't a part of those particular toppers. I covered everything with king size bed sheets. At 6'1" the additional height added by the 4" topper, makes it easier to stand up in the morning, when getting out of bed. A real blessing to wake up in the morning and be energized. No more pain in my hips or shoulders. Super comfy. Best $85.00 purchase you'll ever make. A no brainer. I give this topper 5 well deserved gold stars ⭐⭐⭐⭐⭐ 👍

This pad envelopes you in firm plushiness! The foam is dense enough that it supports you and actually forms nicely to the contour of your body. The cover has pockets, so it fits right over the foam and mattress keeping everything fixed so no sliding around. There was a slight odor of the foam, but once it all opened I did bring it out for a couple hours of air and it dissipated nicely. 100% recommend.

Impressed. Very nice feel of fabric and the thick memory foam is very soft. I wouldn’t personally rate this mattress in the medium range, but closer to soft. However, your body sinks into the comfort of the material.

Makes my bed feel like new. I have a thinner mattress and this topper makes my bed feel wonderful. The topper is not overly soft or firm, just right. The memory foam is nice. It fits my double mattress well. The thickness is great. Not hot or cold.
