Futon - sofa converts to double bed (Stamford PE9)

White futon, converts from sofa to double bed. Wooden frame underneath that folds out. Please note that the mattress has had a few rips that have been repaired with duct tape that has held up fine some time. Also the mattress has some marks / stains. However it doesn’t notice when the canvas cover is on the sofa or bedsheets are used on the mattress. Will give away the blue cushions in the picture too if wanted.
