Review on 🌊 Hypoallergenic 100% Waterproof Mattress Protector | SLEEP TITE - Cal King | 15-Year U.S. Warranty | Vinyl-Free by Vickie Palmer

First of all, this mattress topper is 60% cheaper than the brand, mattress stores try to tell you what you need so they're already stealing. When it's on the mattress you don't even notice it, the terry cloth top and polyurethane lining won't cause a rustle as you move across the bed. Just for a basic test, I also ran the terry cloth side under running water and it didn't seep into the material. Maybe it would be better to test what happens if you drain it to the surface to see what happens. If you turn the lid over and look at the back, you'll see a layer of highly flexible polyurethane coating; this is your seal. The dimensions of the terry surface are great, as is the size of the material for the walls. I can easily cover both the mattress and the 9 inch springs on our Cal King bed. The tread hasn't been worn often enough or used long enough to test durability, but the design and construction itself is far better than others I've used. previously bought.
