Excellent Protection and Comfort
I recently purchased the “Casper Sleep Waterproof Mattress Protector, Queen, White” and I couldn’t be happier with my decision. This mattress protector has exceeded my expectations in every way. First and foremost, the waterproof feature is outstanding. It effectively protects my mattress from spills and accidents, giving me peace of mind. Despite being waterproof, it remains breathable, ensuring that my mattress stays cool and comfortable throughout the night. The fit is perfect. The unique elastic skirting and 360-degree grip ensure that the protector stays securely in place, even with a lot of movement. It fits my queen-sized Casper mattress like a glove and doesn’t shift or bunch up. One of the best aspects is that it doesn’t affect the feel of my mattress. The protector is quiet and doesn’t create any crinkling noise, which is a common issue with other waterproof protectors. It feels soft and smooth, adding an extra layer of comfort without compromising the original feel of the mattress. Overall, I highly recommend the “Casper Sleep Waterproof Mattress Protector” to anyone looking to protect their mattress without sacrificing comfort. It’s a bit on the pricier side, but the quality and peace of mind it provides are well worth the investment.

Definitely yes!
Second one, the first one lasted close to seven years, great quality, not the cheapest but definitely worth it!

These are the best!
I have had one of these on my Queen size mattress for about 4 years, and another not on my Full size mattress. They don't feel cheap, thin, or plasticky, all reasons I have returned every other cover I have tried. These are extremely well made and high quality, and they are very tight fitting to the mattress. The tight fit around the edges turns any slightly too jelly mattress into a supportive, slightly stiffer mattress with more edge support than without the cover. Like soft cottony feeling pantyhose for your mattress! I really think having it on my queen mattress has extended the comfortable life of the mattress by propping it up on all sides. So I just bought another for the Full size in the guest room. This is not a compensated endorsement, I just love these washable waterproof covers, and I also love my washable Casper pillows. Those unzip to throw the inner pillow into the wash, or just to use the outer pillow if you prefer a thinner pillow. The pillows really perk up with a few minutes in the dryer (each of the two components separately put in the machine). Mine are still perfectly new feeling after 5 years.

mattress topper than finally doesn't move!
This mattress topper stays in place great! I love how it stretches far underneath my mattress so it doesn't move.

Satisfied but Not What I Expected
Let me start by saying I do not own a Casper mattress. I have a regular mattress with a 3" memory foam topper. I have been using a cheap waterproof mattress pad for several months but got tired of waking in a puddle of sweat since it did not breathe. I decided to purchase this premium protector based on the reviews available online. The fit, and thickness of this protector is outstanding! I love the way is holds my mattress topper in place and my bed looks sharp after it is made. The bad news is I did not like sleeping on the surface and it took me one night to figure that out. I didn't sweat so I accomplished the breathing that I wanted but it felt like a hard surface to sleep on so I did not rest well. Next day I purchased the Serta Luxury Knit Mattress Pad from my local Sam's Club to place on top of the mattress protector and I have the softness that I want. Yes, I now have three toppers on my mattress but everything is fitting snug and I did not sweat last night. This protector may feel different on a Casper mattress and you will not need the additional pad. Just be prepared that you might lose you luxury softness when you add this protector alone.

Works Great and Quiet
We have two small kids and we tried several covers. Some made a lot of noise, some did not fit well, some would start leaking after washed a few times. We wash and dry on delicate, sometimes just air dry these on the porch railing. They will eventually leak after many washes, but they are very durable, best we’ve tried. The sides make them fit snug in varying mattress thickness and the tops are soft and quiet. Fantastic buy.

A must have when you buy a new Casper Mattress
I bought my second Casper Mattress and needed a mattress protector to protect it. I made the mistake of buying a cheaper version from a mattress store. It didn’t fit well and was difficult to take on and off to wash and clean it. I didn’t want to make the same mistake so I invested in a Casper brand mattress protector specifically designed to fit well and protect my new mattress. Honestly I can’t rate the “water resistance” because (knock on wood) I haven’t spilled any liquid on the mattress and I hope I didn’t just jinx myself LOL. If you are buying a Casper Mattress then do yourself a favor and invest in a mattress protective cover that is specifically designed to fit and feel good underneath your sheets; buy a Casper Mattress Cover.

You don’t even know it’s there
The greatest feature to me is knowing that our mattress is protected, and you don’t even know the mattress protector is there. You don’t feel it, and you don’t hear any plastic-y crinkle noise. You can’t tell it’s on the mattress at all (also to note, we do have a Casper mattress as well). Overall, very happy with this product. We haven’t had to test the waterproof feature thankfully, so I can’t review anything on the waterproof ability on it, but I think we would buy this mattress protector again if needed.
