A mattress topper adds a layer of cushioning on top of a mattress you already own, which can soften a firm bed without replacing it. These four queen-size memory foam toppers come from Tempur-Pedic, Casper, Layla and Nectar.
How We Chose
We picked one queen-size memory foam topper from each of Tempur-Pedic, Casper, Layla and Nectar. They are not identical: the Tempur-Pedic and Casper are 3 inches thick and the Layla and Nectar are 2 inches, and the foams and covers differ, so compare thickness and feel before price. This is a researched comparison, and prices were checked this month. Specs come from each manufacturer’s own page where it gives them. Warranty terms come from the manufacturer’s own website where it names the model or product line, then from the Amazon listing, and we say so where neither gave a length. Each card lists the warranty.

Check Price on Amazon →Our Take
For the lowest price and the extra thickness, the Casper is the straightforward choice. Pick the Tempur-Pedic if you want a removable, washable cover and a 10 year limited warranty, and the Layla or Nectar if you prefer a 2 inch topper with CertiPUR-US certification. Check each company’s care instructions, since only some covers come off.

Which of these toppers are CertiPUR-US certified?
Layla and Nectar list CertiPUR-US certification on their pages. The Tempur-Pedic and Casper pages we read do not state a certification.
