John Lewis is currently promoting their collection of beanbags, the best of which undoubtedly being the Sanderson Dandelion Beanbag.
Here a piece of furniture more often associated with the late 1960s and 1970s is mixed with a 1950s style fabric, but I think it works well. The Dandelion fabric is in the “Chaffinch” colourway, which is various shades of green.
The beanbag costs £95 from John Lewis.
