It took me a few nights to get accustomed to it. After 4 nights or so, my body adjusted to the difference mattress and I have slept very well. The split king is great if you enjoy difference settings or if one of you likes to read at night. It is tougher to cuddle in since there is a gap in the middle of the two mattresses but we just put a regular king sheet over, rather than two individuals. The whole package is a great investment. We love the zero gravity option for watching tv or reading. It really feels great on the body.
