Mainstays 2" Memory Foam Mattress Topper review

Mainstays is Walmart's house brand, and this 2-inch topper is its most rated foam layer. The listing describes 2 inches of gel memory foam with a medium feel, sized at 79 by 59 inches for a queen and weighing just under 12 lb. It ships compressed and rolled, so you unroll it on the mattress and let it expand. Walmart.com sold the queen for $58.00 when we checked, with twin at $40 and king at $78, and the same listing offers 3-inch and 4-inch versions if you want more depth, with a 4-inch queen at $108. More than 8,000 shoppers have rated it, averaging 4.4 out of 5, which is the largest pool of feedback of any topper here. It is basic: there is no cover, care is spot clean only, and the specs say there is no written warranty, so buy a mattress protector to go over it.
