Sleep Innovations 4" Dual Layer Gel Memory Foam Mattress Topper review

Sleep Innovations combines two kinds of topper in one. The top is a 2-inch quilted pillow top cover filled with fiberfill, and under it is 2 inches of cooling gel memory foam, for what the listing calls a medium plush feel suited to all sleep positions. The cover is removable and washable and stretches over the mattress like a fitted sheet, which also helps keep the foam from sliding. The foam is open cell and CertiPUR-US certified, and the 10-year limited warranty is the longest of any topper on this list. On Walmart.com the queen was $139.99 when we checked, sold and shipped by a marketplace seller, Comfort Co, rather than by Walmart itself, so return terms follow that seller. That price puts it above the Zinus and Lucid picks, but it is the only one here that pairs foam with a washable pillow top.
