i purchased this for a full size bed but, after ordering, i was concerned about the fit because i have to get deep pocket sheets for the mattress and thought maybe i should have ordered a queen size. To my surprise it fit perfectly over the mattress and down the sides; a queen would have been too large. very pleased with the product !!

First my toddlers twin size deep mattress perfectly. It doesn't leave the mattress feeling like you are laying on a plastic bedcover and still protects the mattress from overnight accidents. I wash it in hot water, but only air dry it to make it last longer.
