COMFORTABLE AND WORTH THE MONEY
Size: Queen
Excellent mattress topper. Its thick and paired with my matress provides a high end hotel feel. I have had it for a few months and it has not lost its shape and stays in place. Worth the money. You are definitely getting what you paid for.

Wow!!!
Size: King
I couldn’t be happier with this mattress cover—it completely transformed my sleep.
I had one of the best nights of sleep I’ve had in a long time—no tossing and turning, just pure comfort. It stays in place nicely and feels high-quality and well-made. Fluffy without the bulk.
If you’re looking to upgrade your sleep without buying a whole new mattress, this is absolutely worth it. Highly recommend!

Best sleep matress topper
Size: Queen
Ordered after running out of options to get a good night's rest. Placed Q sized mattress topper on a tempur pedic matress and 1st night slept like a baby on a cloud. Ever since then I have knocked out after sleeping and moved less at night. Restful sleep has blessed out house again. It feels like a hotel comfy mattress. Totally recommend.

It’s like a nice hug.
Size: Queen
I find this mattress pad very comfortable to sleep on. I originally bought it because my mattress was too hard. The mattress pad solved the problem. It’s nicely quilted making it very cushy. I’m very happy with it.
