California King Size 2 Inch Memory Foam Mattress Topper (Gel-Infused) from Capsa Sleep (Made in USA)

Definitely improved my sleep, however it would be better if it were 4-6 inches wider. It reaches from top to bottom, but not side to side (yes I tried rotating it 90 degrees, and then it hung over the sides and was way too short). I sleep alone so it's fine for me. If two people slept in the bed, it wouldn't be so spectacular. The width of the pad is the only reason for the 3 star rating. If it were wider, I would give it 5 stars!

My wife loves it, but I've found that it hurts my back when I sleep on my side (which is most of the time).

I love this gel pad. So soft and comfortable. I sleep so well. Thank you

While it is 2 inches thick it is NOT California king. I have a king size bed and figured I would just cut the difference.... it's a solid 2 inches too short on each side for my king bed.
