Split Top Mattress Pads and sheets are hard to find. We bought the Select Comfort i8 smart bed with split top and this mattress topper fits perfectly. It was easy to put on and held up with no problems. We didn't spill anything on it so can't comment on water resistance, but it seems thick enough to protect the mattress without compromising the feel of the Select Comfort mattress (which is why I bought the bed).
