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.

Very comfortable
Size: 36" X 24", Color: Grey, Size: 36" X 24", Color: Grey
Very soft and dries fast. I did the scoot test on them to test the grip and they passed with flying colors. Got them on a limited deal and it was worth every penny. I will be purchasing more in different colors as there are plenty of options. I haven’t washed them yet but if there’s an issue, I will definitely update this review. They are nice and thick and fell good on your feet.

Nice shower mat
Size: 50" X 30", Color: Navy
I have had it for almost a month now and run it through the washer and dryer. Its nice and soft, decent size I did not use a measuring tape to check how precise the sizing is. Absorbs the water when I step out of the shower well and doesn't feel wet or let anything through. Stays in place on the tile floor. Only challenge has been the robot vacuum cleaner gets trapped on it about half the time, but this might just be a testament to its thick nature.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.
