A fitted-sheet-style protector covers only the top and sides, while an encasement zips around the entire mattress, including the bottom. Encasements provide complete protection against bed bugs and allergens, making them ideal for severe allergies or bug-prone areas.
Quality encasements use thin, breathable fabrics that minimally affect feel. Look for cotton or bamboo tops that are quiet and no-crinkle. Avoid thick vinyl covers if you're concerned about noise or heat retention.
Measure your mattress depth (height) before buying. Most encasements fit standard depths (8-18 inches), but some offer deep pocket versions up to 22 inches. Ensure the zipper runs around the entire perimeter for a snug fit.
Yes, most encasements are machine washable. Use cold water and gentle cycle, then tumble dry low. Avoid fabric softeners as they can reduce waterproofing. Always check the care label.
A properly installed encasement with a bug-proof zipper and sealed seams can trap existing bed bugs and prevent new ones from entering. However, it is not a standalone solution; you may need professional extermination if infestation is present.
