Experience an ideal night's sleep with two adjustable cluster pillows from Serta. Inside, a blend of gel memory foam clusters delivers a balanced medium feel for supportive rest. Plus, these foam clusters are shapeable, so you can pat, fluff, and squish until you've molded the perfect cushion. No matter what kind of sleeper you are – side, back or stomach – you can stack them behind your back or layer them for extra sleep support, or you can share one with a partner. Both pillows are wrapped in cool-touch, double-knit covers that are soft and instantly cool to the touch, helping you relax as soon as you hit the pillow. Combined with pressure-relieving memory foam, you'll stay cool and comfortable night after night.
