Midcentury-style Scope sofa and chair discounted at Joss & Main
You'll need to sign up to the Joss & Main website to get the discount and to take advantage of their curated sales which normally last for three days. This sofa, and its matching chair, are taken from a collection called 'In Retrospect', well worth checking out if you like colourful retro style.
One downside is that you're a bit more limited when it comes to colour: this sofa is only available in turquoise, and the chair in grey, for example.
If you can cope with that, you can order the chair for £617.95 and the sofa for £850.95 (and remember to order before the sale closes in a couple of days!).
