This is a small 2-seater sofa-bed (60" wide and 36" deep when closed), and a bit unusual for IKEA it doesn't break down into flat-pack but it`s quite small so would fit easily in an SUV or minivan. It pulls out twice as far as shown in my photo, but I didn't have the space. the seat unfolds to become the mattress, and there is a storage compartment under the wooden slats. It's complete and basically clean, but we have cats so just beware if you have allergies. See the manual at https://www.ikeaddict.com/ikeapedia/en/Product/s69843748/gb-en/hagalund-two...
I also noted when I was searching for the manual that it seems replacement covers are available online from 3rd parties, but we've not tried them and the one it comes with was what we got from IKEA originally.
