For anyone that stumbles across this post - I have a full size mattress on top of this Hemnes daybed frame and it works perfectly Have been using this for at least 4 years daily. Dont be afraid to try it There are no weird spaces , as the bed frame can roll out, so you can make it custom to fit exactly the width of the full size mattress.
