When you buy a design as an investment piece, it's nice to know it will last – and that's the case with the Vitra EA108 swivel chair by Charles and Ray Eames, which comes with a 30-year guarantee.
Yes, this 1950s chair (specifically dating back to 1958) will be fixed (or replaced) by Vitra at any point in the next 30 years. Which means you can swivel round as much as you like without the worry of seeing your investment fall apart before your very eyes.
Oh yes – and it's a design classic too – perfect for an easy or office chair, complete with a die-cast aluminium frame and a choice of hopsak, leather or netweave in a variety of colours for the finish. Prices start at £1,256.
