Mattress Safe Sofcover Ultimate Mattress Encasement review

Mattress Safe builds the Sofcover Ultimate for the worst case. Its patented Zipper with the Hook closes into a hook at the end of the track, and the company includes a sewn-in loop and a zip-tie so the zipper cannot slide open, which matters when you are trying to starve bugs that are already inside the mattress. Mattress Safe lists the cover as certified to protect against bed bugs, impermeable to bed bugs, dust mites and bacteria, and waterproof and breathable on all sides. It also meets the CFR Title 16 Part 1632 fire retardant standard and is made in the USA. Plus+ sizes stretch across regular and long lengths, and depths run from 5 to 9 inches up to 16 to 22 inches. A twin in the shallowest depth was $91.97 when we checked. The catch is the return policy: Mattress Safe cannot accept returns or exchanges on opened or used products, so measure carefully.
