SureGuard Mattress Encasement review

SureGuard is the closest rival to our top pick and the better choice when depth matters. Instead of one stretch size, each bed size comes in four depth ranges, from 6 to 8 inches up to 17 to 20 inches, so a tall hybrid or pillow top can get a tight fit without strain on the zipper. SureGuard says its super fine zipper with Invisi-Zip and SureSeal technology seals the mattress off from bed bugs, and that the bite-proof membrane also keeps bugs already inside from escaping. The top is 100% cotton terry over TPU backing on all six sides, and the brand lists the cover as independently lab tested and GREENGUARD Gold certified. A queen in the 13 to 16 inch depth was $64.97 on sale when we checked, down from $99.95, with free shipping and a 10-year free replacement warranty. SureGuard advises keeping the mattress sealed for at least a year in a bed bug case.
