Its specific purpose is for sewing, although it might work as a side table or as a general storage unit. But we'll stick with the description of 1950s midcentury sewing box for this item, which is currently up for auction.
Likely 1950s, possibly early 1960s, but obviously of that general era, with a design that uses three shades of wood, those angled legs and a good amount of storage. Specifically, that's two drawers in each side, a lid with spool holders integrated and a central storage area.
Lots of images on the site, should you want a closer look, with condition described as 'excellent' with only the 'slightest' wear. Right now, the auction price is £9.
