Beige 225cm long, 105cm deep and 86 cm high. It's a few years old.
seat cushion is in great condition and still firm, but there is staining of various inks etc. back cushions just need a fluff. When it opens out to bed form, there's a part that needs reinforcing, but otherwise still good to us and I put a mattress topper on top anyway. Friends have said it was the best bed they've ever slept on lol. Just getting a different sofa.

they don't sell my colour anymore but it's here:

Located on 6th floor with lift but it should fit no problem,
