Small children may not complain about it but the futon is way too short for me and too uncomfortable. I'm not sure about an overlay. There is a gap where the upper and lower halves meet and it's horribly uncomfortable to sleep on. A sleeping bag, blanket or foam padding stuffed in the gap may help and you can easily store those under the futon.
