The lounge sofa turns into a double bed in a few simply and easy to do steps, the short video by the manufacturer (IKEA) demonstrates how to do this.

Bedding for those sleeping on the sofa bed can be found in the storage compartment (the seats by the window).

To pull out the sofa, simply pull from under the seats facing the TV, and once the lower section is out using the pull handles to lift up the bed section level with the sofa. 

For your comfort, we have provided a mattress topper, for the sofa bed. This can be found in the long back cushion, simply unzip the cushion to access the mattress topper.

Please ensure the pillows are placed at the end nearest the kitchen area, as this is the side of the sofa that is designed to take the body weight when sleeping.  (Besides far nicer to wake up facing the window than the kitchen!)
