At first, I was scared

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

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!

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.
