So perfectly soft
Size: King, Style: 2 Dark Gray
My husband was complaining about the mattress, and wants to spend a lot of money on a new one like the ones at the Waldorf. I asked him to give me a chance to try to fix it first. Watched youtube videos about hotel style beds, and landed on the need for a mattress topper.
This one is so... very... comfortable. I thought the grid pattern would bother me, but nope. You don't realize how much heat you soak up from your mattress until you get a nice airy layer in between. I almost completely stopped sweating at night, and he's stopped complaining about hurting as much.
This is another of those items that I'm scared of washing too much, but it's held up with care and caution. If it starts to get a bit too squished, I just fluff it in the dryer and the padding poofs right back up. The sides are deep and my mattress sinks right into the pocket with no pulling. I have bad back pain and I am certain this has been helping support my back a bit better, so I wake up more refreshed. I'm sorta popping out of bed like I used to years ago.
He still plans on a new mattress, but this has saved us money, for now, and when we get the new one, this will layer on top like a dream. I'm glad I took the chance on this, it has really improved our rest, and that's so important.

Cloud like plushness without loss of support
Size: Queen, Style: 1 Green
Cloud like plushness while not losing support. Bought a new high end plush mattress and adjustable bed frame with massage and still wasn’t feeling that cloud like feeling that I like. I don’t like foam toppers because it is too soft and it lacks support. This topper fit perfectly on a 13” tight top mattress over the protector. The topper was exactly what I was looking for. So comfortable, cool, and put me to sleep right away. Massage feature on adjustable base feels the same as it did without the topper, but the bed is just more comfortable and hard to not want to be lazy in it all day now. For the price, this can’t be beat. If you’re looking for a mattress topper to enhance the comfort of what you already have, buy this. You won’t be disappointed!

Very, very soft and cushiony that I can feel even thru the fitted sheet .
Size: King, Style: 1 Green
Very well packaged. Box was very heavy, but once I got thr shrink wrapped package opened, it inflated on its own. It is a perfect fit. Although it isn't thick, it is extremely soft and my back and hip feel better (arthritis and sciatica). I plan on getting a memory foam pad to put underneath, but for now, I am reasonably pleased. The quality was so good, I decided to keep it instead of going thru the trouble of repacking it.

Nice protector cover, quiet and comfy - best for THICK mattresses
Color: 3 Navy Blue, Size: Full
I liked this pad immediately as fabric cover has nice quilting (just slightly puffy), and touch feel and feels substantial enough to hold up over time. I’ve ordered a few different brands of these and they were crappy, insubstantial pads I did not think would hold up to more than a couple washings.
My biggest complaint and it’s due to my own lack of experience buying these in the new world of skillions of mattress thickness choices is that (A) the side panels / elastic pockets are HUGE and will never be secure on anything thinner than a 12” (or thicker!) mattress; and (B) I thought I was buying an ENCASEMENT cover pad which this is not. I’m blaming that on Amazon because I specifically input “encasement” in the search and their F’ing search algorithm does whatever the heck it wants and if you’re not paying nit-picky attention you get stuff you don’t want. (Or you waste time sorting out the ones you didn’t want to see in the first place!)
That said I am seriously considering keeping this (depending on late arrivals of competing covers) as I’m certain this will be comfortable and as quiet as these waterproof covers get. It’s a nice cover.
UPDATE: it’s a couple weeks later and I’m reporting I did keep it and am happy to have done so. It installed more securely than anticipated and is as comfortable as I thought it would be. I’ll try and update again when I have time to resize pics and show how much my cat enjoys it too:)
UPDATE#2: in review I noticed that the 1* reviews were on about nasty liquids leaking through - I haven’t had any large scale events to gauge but I can see how those reviews could be valid. I should report out of EVERY type of these “nice” noiseless “waterproof” pads I’ve got I think every one of them probably could have the same fault. In other words though I use and really like this cover I also purposely use an encasement style mattress protector (you know the put it in a bag w/zipper kind and a pain in the a** to do so kind) to avoid the complaints in the 1* camp. These mattresses are just too costly and spongelike to NOT protect them completely so I appreciate their frustration that things leaked for them. In my choice to keep this I did so because a) it most probably is pretty waterproof & is definitely quiet & comfy; b) it’s pretty easily washable; and c) because most of the encasement protectors are of more “crinkly” material than this (at least the ones I’ve seen so far - maybe the super expensive ones have figured out how to be perfectly waterproof without crinkle) and by using this nice top protector I put a layer on top of the crinklier encasement and everything just ends up much better with no noticeable crinkle. Figured I say this to help detail 1* vs. 5* because right!? how can one thing be so great and when you turn around then be so terrible… just sayin. (& I did not change my 5* rating😎)
