If you need to change the bed linens, you'll find fresh ones in the brown sideboard next to the sofa.
The sofa can also be converted into a bed. To do so, unlock the two metal safety latches on the back (they’re brown), fold the sides down, and place the sofa cushions on the unfolded ends. Please make sure to cover the sofa with proper bedding before sleeping on it.
Additional pillows and blankets can be found under or inside the sofa.
