Twin beds with cable ties "mate"
In apartments you will find mostly practical furniture that can be moved and put together individually. Bad luck, when you sleep as a couple in two single beds that always slip apart as soon as you want to get closer.
Cable ties wrapped around the legs of the beds, possibly also around bed posts or other suitable place, keeps the beds together securely and protects against the crash in the visitors. We tried it :-).
Anyone who has reservations can take a few more. Does not take up much space, protects the furniture and is easy to remove with a pocket knife.
