Raft 3 seater sofa some damage (SE7)

I bought this sofa from Raft about 8 years ago.
(Cost over £1,600) It's showing some signs of wear, cat has damaged sides, some sun bleaching and a few stains. The seat and back covers are zipped and would benefit from dry cleaning. The sides apparently fold down for ease of moving, but no idea how! The long section can be used left or right side. 3 cushions come with it.
You will need 2 or 3 fairly strong people to collect as it's a first floor flat. I'd really like it gone before June 7th. Measures 88 ins long, 39 ins wide and 23 ins deep basic sofa. The long L shape part adds 25 × 34 ins to total.
