People use “bed cover” to describe a few different items. Here’s a quick guide so you can find the right one:

• Mattress protector: A thin layer that helps shield your mattress from spills and everyday wear; often waterproof and breathable. Comes in fitted or zippered styles.
• Mattress pad: A quilted topper that adds light cushioning plus surface protection; usually fitted like a sheet.
• Mattress encasement: A six-sided, zippered cover that fully encloses the mattress; commonly used for allergen and bed bug barriers.
• Mattress topper: Thicker comfort layer (e.g., pillow top); some include protective covers.
• Mattress bag: Heavy-duty plastic cover used for moving or storage.
• Duvet cover: Protects a comforter (not the mattress) and updates the look of your bed.

Checking these terms on the product page can help you quickly narrow your search.

Start with what you need most, then match features:

• Spill protection: Look for a waterproof, noiseless mattress protector. Fitted styles are easy on/off for weekly use.
• Cooling feel: Choose breathable fabrics (e.g., 3D air knit or rayon made from bamboo) to help with heat buildup.
• Allergen/bed bug concerns: A zippered, six-sided encasement offers full coverage and an added barrier.
• Extra comfort: A quilted mattress pad or pillow-top style can add cushioning while still protecting.
• Moving/storage: Use a heavy-duty mattress bag to help keep the mattress clean in transit.

Fit tip: Check your mattress depth and select a pocket range (e.g., 8–21 inches) that accommodates it. Reviewing product details and customer feedback can help you decide.

Care instructions vary by product, so always check the label or product page first. In general, these tips can help:

• Fabric protectors/pads: Close any zippers, machine wash on cold with mild detergent, and use a gentle cycle. Avoid bleach and fabric softener, which may affect waterproof membranes.
• Drying: Tumble dry on low or air dry to help preserve the backing. High heat may reduce performance over time.
• Quilted pads: Wash separately to reduce friction, and consider an extra rinse to remove detergent residue.
• Vinyl/plastic covers or moving bags: Wipe clean or spot clean as directed; machine drying typically isn’t recommended.

Allow the protector to dry completely before putting it back on the bed. Results may vary based on materials and care conditions.

You can shop a wide selection online and in stores:

• Online: Visit Walmart.com or the Walmart app and search for terms like “mattress protector,” “zippered encasement,” or “waterproof mattress pad.” Use filters for size, features (e.g., cooling, bed bug protection), and pocket depth.
• In store: Check the bedding section for fitted protectors, pads, and encasements. Availability varies by location.
• Convenience: Many areas offer pickup and delivery options. You can also review product details, care instructions, and customer ratings to help you choose.

Measuring your mattress before you buy can make the selection process quicker and reduce returns.

A good fit helps performance and comfort. Here’s how to size up:

• Measure depth: Measure from the bottom to the top of the mattress (include any pillow-top or topper). Compare to the product’s pocket range (e.g., 8–21 inches).
• Match length/width: Choose the correct bed size (Twin, Twin XL, Full, Queen, King, etc.). Twin XL is longer than Twin.
• Encasements: For six-sided zippered covers, match the height closely so there’s not too much excess fabric.
• Special sizes: Cribs and airbeds typically need size-specific covers.
• If in between: Consider the next deeper pocket range to avoid strain on seams.

Checking the product’s size chart and fit notes can help you select the most suitable option.
