It was one of the most affordable mattress toppers for the quality, and the only one in the area that was readily available. Did extensive research, and we are completely satisfied by this purchase. The information provided on the website as well as reliability regarding day-of pickup information was amazing.

Firm, but Cozy.

I bought my son a cheap 6" hard mattress online when he was 11. Now that he's a teenager, it's not working for him. But this mattress foam is amazing and transformed it into a new bed! I'm old and fat, and my goodness, I layed on his bed, and it didn't hurt my hips like before. It feels just like my expensive firm memory foam mattress now. A cheap hard mattress with this foam on top is the perfect combo. It's still firm, but much cozier.

Nice cushy mattress topper

this Mainstays mattress topper was a twin XL, very easy to trim off the excess for my twin bed. expanded within 24 hours, thankfully no odor. It's more fluffy than supportive, very comfortable. Added a 2" flat-surfaced Mainstays topper to the pile, for a little more protection on a very firm older mattress, but happy with this one as well. Thank you, Walmart!
