Decent little beds for when guests stay. Not comfortable for long-term use unless maybe for a child, but certainly not for an adult.
Mattress is quite small and thin, we found it made for a much more comfortable sleep with an adult when we put our sofa cushions underneath to give it a bit more stability otherwise sometimes when moving you could feel the metal bar in the middle. We are planning to buy either another thing mattress to go on top or something similar.
They do fold away and with the wheels are easy to use, as our spare room is mainly used as a home office, we found these great!

Could maybe do with the mattresses being a bit more sturdy as they are very thing foam.
