Purple designed its Waterproof Mattress Protector for its own beds, whose GelFlex Grid needs to flex freely to relieve pressure. The protector adds stretch so it moves with the grid, and Purple says it is 100% waterproof and stain resistant, with a silent, no-crinkle knit top that is anti-microbial and hypoallergenic. It is made of polyester with a thermoplastic polyurethane coating and is machine washable on cold. Purple sells two depths: Standard for mattresses 8 to 15.5 inches tall and Deep Pocket for 15.5 to 20 inches, the deepest fit on this list after Avocado. Shipping is free, returns are accepted for 30 days if the protector is clean and undamaged, though the buyer pays return shipping, and Purple will replace a faulty product for up to 10 years. We could not load a USD price from our location, so the cost is marked as pending and its value score is conservative.
Who it is for
Purple mattress owners and anyone with a very tall mattress up to 20 inches.
