Linenspa 3" Cooling Gel and Green Tea Infused Memory Foam Mattress Topper review

Linenspa's topper gives you the most foam per dollar on this list. The 3-inch queen is plush memory foam infused with cooling gel and green tea, and Linenspa describes the formula as lightweight and breathable. The same listing offers 2-inch medium plush and 4-inch extra-plush profiles, and sizes run from twin to king, including full XL. The foam is CertiPUR-US certified, ships rolled and compressed in one box, and Linenspa backs it with a 3-year warranty, which is better than the Mainstays and Sealy toppers here. Walmart.com showed the 3-inch queen at $39.58, down from $46.56, when we checked, and the 4-inch queen at $84.99. The listing is newer, with 117 ratings averaging 4.0, so there is less shopper feedback than for Mainstays or Zinus. Like most cheap foam, it has no cover and is spot clean only.
