The liner hugs the 52x34 edges just right, so no bunching under the sheets. It’s held up through two washes already, and the waterproof backing does its job without feeling crinkly.

Evelyn U. ★★★★★ Oct 19, 2026

The sizing options made it easy to get a perfect fit for my XL bed, and the waterproof layer held up well during an accidental spill. I appreciate that the liner is discreet and doesn't add bulk to the mattress.

The XL fit my 52x34 mattress perfectly with no bunching at the corners. I've washed it twice already and it's still completely waterproof underneath.
