Pleasantly surprised!
Size: Queen, Style: 2 Dark Gray
I had been searching for a quality mattress topper in hopes of extending the life of our mattress. I compared a few options and kept coming back to this one. I have to admit I was skeptical because the price point was lower than many options. This topper is SO comfortable and soft! I left it laying out for a couple hours and then followed the instructions to put it in the dryer. Worked like a charm. I’ve been going through issues with hip pain and this has made a difference in my sleep and I’m waking up in less pain. So happy I tried this out. The padding is so comfortable and fit on the mattress using the same sheet we had.

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.
