Key item features

  • WATERPROOF MATTRESS PROTECTOR, NOT A PADDED TOPPER: A thin barrier that keeps liquid off the top sleeping surface of your mattress. It adds no cushioning and will not change how firm your bed feels.
  • WANT AN EXTRA LAYER OF SOFTNESS? CHOOSE THE PAD: If you want an extra layer of softness, choose our Mattress Pad instead.
  • FITS 8 TO 20 INCH MATTRESSES — TWIN XL 39" W x 80" L: Twin XL protector measures 39" W x 80" L and fits like a fitted sheet, with all-around elastic and stretch pockets that hold mattresses 8 to 20 inches deep, including pillow tops.
  • MEASURE YOUR MATTRESS DEPTH BEFORE ORDERING: Measure your mattress depth before ordering, as depth is the most common sizing mistake on this product.
  • MACHINE WASH COLD, TUMBLE DRY LOW: Wash separately on a gentle cycle. Use non-chlorine bleach only if needed.
  • WHAT DAMAGES THE WATERPROOF LAYER: Skip the iron, chlorine bleach and high heat, because all three damage the waterproof layer and are the usual reason a protector starts letting liquid through.
  • SOFT SURFACE, NOT PLASTIC SHEETING: The rayon-blend top feels like fabric rather than plastic sheeting, so it does not change how your sheets feel over it.
  • NO CRINKLE, STAYS QUIET WHEN YOU TURN OVER: It stays quiet when you turn over, with none of the rustling that makes some protectors impossible to ignore.
  • OEKO-TEX STANDARD 100 CERTIFIED: Every item bearing the OEKO-TEX STANDARD 100 label is certified as having passed safety tests for harmful substances.
  • PLASTIC-FREE PACKAGING: Ships in plastic-free packaging. Colors may vary slightly between screen display and physical fabric.

About this item

Product details

The California Design Den twin xl mattress protector waterproof bedding is a thin liquid barrier, not a padded topper. It goes on like a fitted sheet, sits under your sheets, and keeps spills, sweat, and accidents off the top sleeping surface of the mattress. This xl twin mattress protector adds no cushioning and will not change how firm the bed feels. If you want an extra layer of softness, our Mattress Pad is the right product instead. All-around elastic and stretch pockets hold mattresses 8 to 20 inches deep, covering thin guest-room mattresses to thick pillow tops. Depth is the most common sizing mistake in this category, so measure from the top of the mattress down to the base before ordering. The rayon-blend top of this mattress protector twin xl size feels like fabric rather than plastic sheeting, so your sheets feel the same over it. It stays quiet when you turn over, without the crinkle that makes some protectors impossible to sleep on. Machine wash cold, tumble dry low, wash separately on a gentle cycle, and use non-chlorine bleach only if needed. Skip the iron, chlorine bleach or high heat — all three damage the waterproof layer, the usual reason a protector starts letting liquid through. Every item bearing the OEKO-TEX STANDARD 100 label is certified as having passed safety tests for harmful substances. Ships in plastic-free packaging.

GREAT PRODUCT FOR THE PRICE

It is waterproof but doesn't make a crinkle sound when you lay on it. Great price too considering it is made from bamboo. I always have trouble with mattress pads that aren't deep enough and also tear when you try to put them on. Made of very sturdy material and fits snug on my mattres.
