Look at what you sit on at home: the sofa, the dining chairs, the armchair by the window. Leather, linen, wool, all chosen with some care. Then there’s the exercise ball, the one seat in the house made of shiny plastic, which is exactly why it gets sat on so rarely. Alama covers it in the natural leather Italian supercars are upholstered in, stitched in panels, 65 cm across. It grips under a bare hand, holds its own next to the sofa, and does what a ball does: keeps your core quietly working while you read, take a call or watch the match. A ball only helps when you’re on it. This is one you’ll want to be on.
