Quick verdict
In my original test, the Nest cooling protector felt less thick and slippery under sheets than the Malouf protector I compared it with. Nest currently sells a Cooling Cotton Waterproof Mattress Protector, but its materials and design may differ from the earlier sample, so check the exact version before buying.
Best for: shoppers who want waterproof coverage with a cotton surface and a choice of fitted or encasement styles. Consider another option if: you need a protector for a mattress deeper than the listed 18-inch pocket or expect a guarantee of cooler sleep.
The videos below show the original review and infrared demonstration; they should not be treated as a controlled overnight cooling test of the current product.
My original test
I liked the presentation of the earlier Nest protector and the included thank-you card. In my comparison at the time, the Malouf protector felt thicker and more slippery, which I thought could allow fitted sheets to shift more easily. The Nest sample felt less intrusive to the mattress underneath.
I used an infrared camera in the original video to illustrate how the earlier sample dissipated heat. That observation does not establish how the current protector performs over an entire night or for every sleeper.
Current Cooling Cotton protector
Nest currently lists an 18-inch Cooling Cotton Waterproof Mattress Protector. The listing describes a cotton top, a polyester-spandex skirt and a thermoplastic polyurethane waterproof lamination. It offers a five-sided fitted style and a six-sided zippered encasement. This is a current listing; the original review covered an earlier product and does not establish that the materials are identical.
Nest markets the current protector for cooling. How cool it feels depends on the mattress, sheets, room and sleeper; we have not conducted an overnight comparison of the current model.
Fit, care and buying
Nest lists an 18-inch pocket depth. Measure your mattress and any topper together. Five-sided protection covers the top and sides like a fitted sheet; the encasement encloses all six sides. Choose the coverage that suits your needs and verify the size before ordering.
For the current model, Nest recommends a separate cold delicate wash with mild detergent and low tumble drying; no bleach, ironing or dry cleaning. Follow the label on the product you receive. The product page advertises a 30-night trial, with terms and pricing subject to change; verify the current offer with the seller.
