M&S collaborated with furniture brand Ercol to produce the Kimble range, based on 1950's Ercol designs. This coffee table, model no. 1459 is likely based on the classic Ercol coffee table, model no. 459. This table has a similar rounded top and splayed legs. The frame is in traditional beech but the top is ash and the spindle shelf under has 17 spindles running perpendicular to the top rather than in parallel. All the wood is treated in the 'light' colour, soft matt, finish. While not from the original Windsor collection, this is immediately recognisable as Ercol.
