At first, I was scared

Taylor April 22, 2025

I unrolled this mattress topper and was nervous because it was rolled so tightly. If it puffed up and I didn't like it, how would I return it??? Lol. Well, it took about 20 to 30 minutes to reach it's full size, and I love it. She thicc! I thought it was a few inches short width wise, but I just had it on my bed the wrong way. It fits perfectly. 10/10 BEST SLEEP EVER! Mine didn't smell, but there was a warning on a piece of paper about possible smell. I found it funny because they called it a "foam fresh" smell 😂

Supportive but warm

TheNikki May 23, 2023

I put this on my guest bed which is a little firm. My nephew spent the night and according to him it “surrounded his behind perfectly”. He has never experienced memory foam before and absolutely loved it. I tried it out for a night myself and if improved the bed immensely. It was supportive and comfortable the only downside was I felt like I got quite warm overnight.

So comfortable!

Becca0716 May 9, 2023

This mattress topper is very comfortable and makes a great addition to any mattress. It fits a Queen-sized mattress perfectly. The only thing I don’t like is the smell. It smells vaguely like a permanent marker, but I’m guessing that’s because it’s new.

Memory foam bed pad

Melinda June 4, 2023

The 2" memory foam bed mattress pad is fit for a queen size bed, stays in place when I put the sheet on. It helped me sleep just for a bit. It does not help me cool so basically it's for the cold weather, just my opinion. It's good to put on air mattress if needed extra cushioning and it worked well.

Don’t recommend

quincy November 6, 2025

Don’t buy. Couldn’t tell if this was previously used or not, it had some yellowing on the edges. I ordered a full size and it was way too small. I gave it a few days to inflate but it never did in some spots. Returned.

Has holes throughout!

Jodes December 15, 2025

First off, there's holes everywhere on this pad. Small holes large holes makes me think they're all insect holes or possibly bubble holes when they made foam? I don't know enough about memory foam to know that? this does not resemble something that is high quality. It seems like seconds, because of the material not being good. This honestly should be sold as seconds. Terrible quality. so be warned. Also the wrapping was very weird. It was plastic wrapped very tightly and where the sticker said pool here was in the wrong place. I felt it wasn't going to expand far enough to fit my bed but it did finally go into a king size mattress pad. Now it's just too big and cumbersome to return. Very disappointed in the product. It also has a very strong smell so make sure to ventilate. I've had other memory foam pads and not one ever had holes in it. Although sadly most do have some type of smell. Personally I would order a different mattress pad since this one is clearly seconds and should not be sold as high quality.

Horrible

Lynn May 22, 2025

Did not even come close to fitting my mattress or taking proper shape after opening. Complete waste of time

one of the peice I got is completely out of shape. looks like it wasn't cut properly. I can't even return it now, as it is completely opened up.
