Excellent Mattress Protector – Perfect for Our Catamaran
We purchased the SafeRest Waterproof King Size Mattress Protector to use on our Leopard 40 Catamaran, and it has worked out perfectly. Our bed is an unusual size since it is larger than a queen but smaller than a king and this protector fits it very well. It’s also very easy to put on. You install it just like a fitted sheet, so it goes on quickly and stays securely in place around the mattress. One of the things we really appreciate is how comfortable it is. Unlike some waterproof protectors, it doesn’t make any crunchy or plastic-like noise when you move around. It’s soft and quiet, so it feels just like sleeping on a normal mattress cover. The waterproof feature works exactly as advertised. I accidentally spilled water on the bed, and the mattress underneath stayed completely dry. That alone gives us a lot of peace of mind, especially on a boat where protecting bedding is important. Overall, this is a high-quality mattress protector that is comfortable, quiet, easy to install, and truly waterproof. We’re very happy with it and would absolutely recommend it.

Worth the money
There was one review on here that stated his wife's water broke and the mattress was dry. Based on that I ordered it. We have had it for years and with pet accidents and drink spills it has kept our mattress in perfect condition. It has been washed a million times and still works fine. I recently ordered another one to make bed changing easier than having to always wait for the only one to be washed and dried. Great quality and perfect for thicker mattress. It never rolls up or have any problems with it staying put. We have a sleep number bed and it works perfect.

Nice fit on my queen mattress
Nice fit on my queen mattress. If you are going to spend a decent amount of money on a quality mattress then you definitely should invest a little bit on some protection for it. I've had a couple drink spills on it and even though it seeped through my sheets it did not seep through the mattress protecter.

Reliable Waterproofing with Good Durability
The SafeRest Twin waterproof mattress protector has provided effective protection for our child's mattress over the past year, successfully preventing multiple spills and accidents from reaching the mattress. The fitted design with stretchable pockets stays securely in place on the twin mattress without shifting or bunching, even with an active sleeper. What works well is the dependable waterproof barrier that has passed every test - from water spills to bedwetting incidents. The liquid beads up on the surface and wipes away easily without any seepage through to the mattress below. This protection gives genuine peace of mind for preserving our mattress investment while dealing with childhood accidents. The machine washable feature is convenient and the protector holds up well through frequent washing cycles. It dries relatively quickly and maintains its waterproof properties wash after wash. The construction feels durable with reinforced seams that show no signs of wear after many laundry cycles. However, there is some trade-off in sleep comfort compared to premium options. While not as crinkly as cheap plastic protectors, there is a subtle texture difference that's noticeable, especially during the first few weeks of use. The breathability is adequate but not exceptional, occasionally creating slightly warmer sleep conditions. The value proposition is strong for basic waterproof protection. While it doesn't offer the premium comfort of higher-end protectors, it delivers reliable function at a budget-friendly price point that works well for children's beds or guest rooms. Recommend for practical waterproof protection on a budget - delivers reliable function with minor comfort compromises compared to premium alternatives.

4 Years of Protection: A Must-Have for Pet Owners!
Functionality & Protection I purchased this SafeRest protector in 2022 specifically because I have elderly cats. It has saved my mattress from "accidents" more than a few times over the last four years. The feel is excellent; it features a soft cloth top over the waterproof layer, so you don’t feel like you are sleeping on a sheet of crinkly plastic. Performance & Comfort One of the best features is the sweat resistance. Despite the waterproof barrier, I haven't noticed any extra warmth or "hot sleeping" issues that usually come with cheaper covers. It remains breathable while staying 100% functional. Sturdiness & Fit It installs easily and very snugly on my Queen mattress. Even after four years of heavy use, I have noticed the sturdiness of the sides despite their thin material. Note that this is a "fitted sheet" style protector, so there is no zipper quality to worry about—it just slips right on and stays put under your regular sheets. Value for Money While the sides might not last much longer, this protector has more than met my expectations for its life expectancy. For the price, the peace of mind it provides for my mattress is well worth it.

Barely notice this under the sheet. Fits snug on our extra deep pillow top king. I was worried it would make us hot but it hasn't yet. I washed it right out of the box, a bit tricky to dry though, because of the plastic backing. I used no heat for 20 minutes then hung to dry over night, no damage to the plastic barrier and the cotton side was nice and soft. Excellent product.

I had initially bought a (not so cheap) mattress cover at Ikea for my 3-year-old’s new bed, it was useless to say the least and ruined his brand new mattress. After doing lots of research so as to not waste my money again I decided on this mattress protector and am I ever glad I did. It is super soft and comfortable, easy to clean, and most importantly VERY reliable. One night we accidentally forgot to put a diaper on him and despite him usually waking up with a completely soaked diaper not a single drop went through the mattress protector. Will be purchasing the same product again for my 1-year-old when the time comes.
