The old has been inspiring the new for ages and retro is still very now. Our current favourite retro-esque sofas are the Arris 2 sofa by Mark Product, £1,500 at John Lewis , and the Avian AV3, £3,440 from TwentyTwentyOne . But if you want the real thing, then have a look at The Modern Warehouse, which has a great selection of authentic designs such as this Rosewood sofa, £1,295
