As always, let me share the product description as it is listed on Amazon:
300 Thread count.
100% Cotton cover
100% Temperature regulating cell solution / polyester fiber fill.
Deep Pockets. Fits all mattresses up to 20" thick.
100% hypoallergenic polyester fiberfill.
Easy care: Machine washable. By far the best and most affordable cooling mattress pad on the market
This cooling mattress is the best product I have gotten in a very long time. A good night's sleep is crucial for me, being the busy mommy that I am, and having a day that never seems to slow down, so if I am not rested, I just can't get everything done that I need to.
With this wonderful cooling mattress, my body is just the right temperature all night long, and I don't find myself waking up throughout the night to adjust the covers to either warm up or cool down. Now my husband is a lot harder to please than me, as he is always too hot, and he doesn't seem to notice much of a difference. The only time he really noticed a difference was when he laid down on the bed before I put sheets on it, then he could really feel the coolness.
The mattress pad itself is very soft, and I have laundered it, and it washed and dried very nicely, and it still continues to work for me as it did the first night I slept on it.
If it were perfect for us both is would get a perfect 5 Star rating from me.
