Bedsure Diamond Quilted Waterproof Mattress Pad review

Bedsure is one of the largest bedding sellers on Amazon, and its Diamond Quilted Waterproof Mattress Pad is the value pick here. It uses four layers: a quilted polyester top for a little extra softness and a TPU waterproof layer that Bedsure says stops liquids from reaching the mattress. Full elastic edging and deep pockets help it stay on, and it is sold in twin through California king in a few colors. The pad is OEKO-TEX Standard 100 certified, and Bedsure's care guide says it can be machine washed and tumble dried on low. A twin was $47.99 on Bedsure's own US store when we checked, and Bedsure also sells a non-waterproof Three-Zone Quilted pad. One caution: the feature list on the page says 22-inch pockets while the size note says it fits mattresses up to 16 inches, so check your mattress height before ordering. The comfort layer is modest, which suits sleepers who want a thin pad.

Who it is for

Budget shoppers and families who want a cushioned pad that is fully waterproof.
