RV 6 Sided Zippered Mattress Protector - Full RV Encasing (38x75 Twin)

In this review of the RV 6 Sided Zippered Mattress Protector the bottom line is simple: it is built for RV and camper owners who need a true full encasement that blocks allergens and liquids. The reviewer found the cover delivers a complete, quiet barrier around an RV mattress and is the single best option when protection from dust, pet dander, pollen and spills matters more than a fitted sheet style protector. Installation is straightforward and the locking zipper is a practical feature that seals the mattress completely.

Key Features

• Full 6-sided protection: The protector zips closed on all six sides to keep dust, pet dander and pollen out of the mattress core.
• Waterproof sides and bottom: Unlike most fitted covers, this encasement protects the mattress from spills and liquids on the top, sides and underside.
• Quiet, breathable fabric: The soft poly knit top stays cool and quiet under sheets and does not rustle like vinyl-backed options.
• Secure locking zipper: A patented auto lock tab plus a Velcro seal keeps the zipper closed and creates a natural seal around the mattress.
• Flexible stretch walls: Stretch side walls with spandex accommodate mattress depths from 9 to 13 in for a snug fit.
• Easy care: The protector is machine washable on hot and tumble dry, making maintenance simple for frequent RV use.

Who It's For

This protector is aimed at RV and camper owners who need complete encasement rather than a fitted sheet style cover: people with allergies, pets onboard, or those who often travel in dusty or pollen-prone environments will benefit most. It is also a strong choice for anyone who wants waterproof protection not only on the top but on the sides and bottom of a 38 by 75 in twin RV mattress.

Shoppers who have very thin mattresses under 9 in or very deep mattresses over 13 in should look elsewhere, since the stretch wall is designed to fit snugly only within that depth range. If you prefer a plush quilted mattress pad for added comfort rather than a thin poly knit barrier, combine this encasement with a separate mattress topper.

Pros & Cons

Pros

• True 6-sided encasement provides comprehensive allergen and liquid protection.
• Quiet, cool fabric avoids the crinkly noise of vinyl-backed protectors and feels soft to the touch.
• Secure, patented locking zipper and Velcro seal create a reliable barrier once closed.
• Machine washable and made by a long-established US company with a lifetime workmanship warranty.

Cons

• Size and depth limits (fits mattresses 9-13 in deep and 38 x 75 in footprint) require measuring before purchase.
• Because it is a full encasement, putting it on may take a short installation time and could be tight on very stiff mattresses.
