Favorite so far
Favorite king pad so far. Feels cool but not cold. Other pads get too warm. It also doesn't slide all over. Does great on inflatable mattresses!
Back support!
This king mattress pad really helps my back. The other brand I had previously was too soft. The ViscoSoft is a huge improvement in support.
both of us are very comfortable.
We bought a new ultra firm mattress for my back, but my wife couldn't sleep on it. After putting the 3' visco soft queen pad on it, both of us are very comfortable.
Just right.
Bought this pad to go over a king mattress that was too hard. The reviews are right, this topper is great. Just the right amount of firmness.I sleep the whole night and wake refreshed.
Quality king mattress pad. Very comfy.
Fits very well and holds firm to the mattress. Doesn't shift around. Going to buy some cooling sheets to go with it. I had the first solid nights sleep in years.
Five Stars
I purchased this based on reviews and I have to say that the reviews were 100% accurate. I've slept on this king pad now for 6 nights and wow improvement from day one. I wake up painless and resume my day pain free.
Absolutely excellent!
I am sleeping much more soundly. I'm 5'4, about 126 lbs and the mattress pad doesn't sink as much as I was concerned it might - more like sleeping on a cloud than in a cocoon.
she looks so comfortable when she is sleeping
I bought the king gel memory pad for my mom. she is not able to walk too much, so most of her time is spent in bed. She absolutely loves it. she looks so comfortable when she is sleeping.

King size for royal comfort
When your bed feels big enough for everyone, mornings just hit differently. A king size mattress pad gives you that kind of space - where couples stretch out freely, and the kids sneak in without waking anyone up. There’s room to roll over, snuggle in, or simply enjoy the quiet before the day begins.
Our king-size memory foam mattress pads are designed to soften every shift and step, so if someone turns over, the other side stays calm. The memory foam inside adapts naturally to your shape, easing pressure while keeping you supported through the night
