You can still buy variations of these new, but when prices can be so cheap for a midcentury basket chair, why would you want to?
There are a few cheap examples on eBay right now, but this one, dating from the 1950s or '60s, is the cheapest of the lot. Details are pretty scarce, but you can see the weaved seating and metal frame, with condition described as 'good'.
Best thing of all? With just a couple of days left, it is still at 99 pence.
