Protect your new Serta mattress for years to come with the Sleep To Go™ by Serta Elite Mattress Encasement. It is designed to resist mold, dust mites, allergens, bacteria, and odors, while remaining cool and breathable. Plus, built-in 3M Scotchgard™ Dual-Action Protection enhances liquid repellency and stain resistance so spills actually bead up and are wiped away easily without ever reaching the mattress! Unlike a mattress protector that goes over the top and sides of your mattress like a fitted sheet, this product encases the entire mattress for enhanced protection. Fits mattress heights of up to 20 inches. Available in Twin, Twin XL, Full, Queen, King and Cal King sizes. 10-year limited warranty.
