SAVE SPACE AND ENERGY - Use vacuum sealing technology to compress your foam mattress to the original size it was when it arrived. This makes it super easy to move and return! The space-saving bag is easy to use and store and has been designed to be compatible with almost all vacuum cleaners. Possibly with double zipper and fastening clips. Our unique double-seal design is engineered to lift all air during the vacuum process and ensure long-lasting compression. The retainer clip ensures that the clip does not come off the zipper or remain. KEEP YOUR MATTRESS SAFE - Our mattress storage bags keep your mattress, clothes and duvets safer to protect against moisture, dust and rain while saving storage space and are ideal for any home. Versatile storage bags - Each space-saving vacuum-sealed bag is designed to hold a matching double mattress for added security. Our mattress protector bags can also be used to store clothes, bulky fabrics, mattresses, pillows, blankets and more.
