The twin sized topper is too large for a normal twin sized mattress, too small for a queen sized mattress and covers two-thirds of a California King mattress...I'm using it on the left side of my California King...it's comfortable, but a little clingy...when we change our sheets, I will re-position the Marshmallow to make it, possibly, a little more balanced...other adjustments will need to be made as well...so, we'll see how it goes...JR

These mattress toppers are amazing. I bought one for my grandparents house in Virginia tried it out loved it. It was a full-size then I ordered a queen size and I just got my shipment and put it on my bed and I cannot wait to try it out tonight love these mattress toppers they’re worth every penny. Thank you.
