DO NOT BUY! ITS LIKE SLEEPING ON A ROCK
This topper was fine for the first few days. It's definitely not as described. It's paper thin with light stuffing. It's about the equivalent of a very flat pillow with half the stuffing. It kills my back. I bought this in hopes of getting some relief ,but here I am in pain again due to a false description. For those who raved about this product. How!?! Definitely not 5inch thick either

Very comfortable
I was a little unsure of this topper when I received it. It almost had a lot of little bumps all in it and I was afraid that would be uncomfortable when sleeping on it. Well, I was wrong. It is comfortable and you don't feel the bumps. It easily fit on my king size mattress and stays in place. I did not notice any odor, but I did leave it out for the day before I put it on. It does not squish down and become flat after using it, so I guess those little bumps are doing their job without causing any discomfort.

Tight fit. Empty fiber picks lack of support.
We followed directions to the T. We purchased the king/cali. It didnt expand. Some pockets seemed to not have as much fiber in them than some. Its is comfortable. But where i lay its dev e loved a hole or indent in it and my hip does get supported.Size wise it fit tight, if someone has a California King bed I will say sorry now.. IT will be too tight.

SHREDDED CHOPPED UP MEMMORY FOAM NOT SOLID PIECE
The memory foam in in chopped up pieces inside the covering NOT SOLID MEMORY FOAM ....I DEFINITELY didn't expect that! DOES NOT expand to the 5 inches thick I wanted or expected!

Not as I had hoped for
What I received looks nothing like this photo. I was expecting it to be more plush and springy but instead it’s clumps of shredded foam so some areas have more fill and other areas have very little. I tried moving it around but it didn’t really work. Also, this comes vacuum sealed so it would be pretty impossible to return it. Disappointed

Looks can be deceiving
I have tried two other name brand mattress toppers costing about 400 dollars each. Both were memory foam and very uncomfortable. The whatsbedding topper looks lumpy but I am experiencing a great nights sleep. The topper hugs the body but still makes position changes easy, no holes to roll out of.
