Linenspa Premium Smooth Mattress Protector review

Linenspa's Premium Smooth protector is the cheapest way to keep a new mattress dry. A twin cost $15.99 on Linenspa's US store when we checked, and the price includes free shipping and a 10-year limited warranty that covers defects in materials and workmanship for products bought in the United States. The build is simple: a 100% polyester top over a 100% polyurethane backing that Linenspa says is fully waterproof and quiet, with no rustling. It slides on like a fitted sheet and is made to be washed often, hot, with your bedding. The brand is also clear about why a protector matters: Linenspa says the warranty on its own mattresses is voided if you do not use one. The trade-offs are size and comfort. It fits mattresses only up to 14 inches thick, so it can be too shallow for tall pillow tops, and the plain polyester top lacks the cooling fabrics of SafeRest, Bear or Tempur-Pedic.
