Coop Sleep Goods Original Mattress Topper review

Coop's Original Mattress Topper is the most direct answer for people who want a thick, fluffy layer rather than a firm foam slab. It is 5 inches tall and built with 3D baffle boxes, internal walls that keep the fill spread across the bed instead of drifting to the edges. Each pocket holds half a pound of cross-cut memory foam mixed with microfiber, so it feels softer than a solid foam topper while still molding to the body. Coop describes the result as a layer of down-like plush comfort and says the crosscut foam segments help airflow. It comes in twin, twin XL, full, queen, king and California king. The price was $171.75 on sale when we checked, down from $229. Coop offers a 100-night trial with free returns, but the warranty is only 1 year, and you will need deep-pocket sheets to fit over a 5-inch layer.
