The Windsor form has lasted three centuries because the spindle back works, and this set of four keeps that construction rather than imitating it in a moulded panel. Vertical spindles rise into a harp-style top rail, and the height of that back means the natural curve of the spine is supported through a long meal instead of stopping at the shoulder blades. The wood is 100 percent natural rubber wood, chosen because it is dimensionally stable and resists warping, which is what keeps a spindle chair from developing the wobble that eventually loosens every joint. Each chair carries 330 lbs, or 150 kg, so the set holds adults of any size without qualification. The seat measures 17 by 17 in and sits 18 in from the floor, generous enough to shift position during a long sitting, and each chair occupies 17 by 19 by 34.5 in of space. The finish is a sleek black that suits dining rooms, kitchens, cafe shops and offices equally, and the surface is smooth throughout, so wiping a spill away takes one pass rather than working around joints and crevices. Assembly is deliberately simple: the spindles arrive pre-installed in the backrest, leaving only the legs and seat to be joined, and four chairs together weigh 40 lbs on delivery. The result is a set that looks considered and takes daily use.
