The seat surface here is contoured to the shape of the hips rather than flat, and at 18 x 17 in it is broad enough to sit on sideways. Elastic sponge under breathable linen keeps it comfortable through a long meal. Each stool swivels a full circle on rubber wood legs braced by a footrest 14.5 in up, and holds 310 lbs. Overall height is 30 in, sized for tables of 40-43 in, on a 20 x 20 in footprint. Each stool weighs 13.5 lbs - light for its size, which makes it easy to reposition around an island. Two stools and a user guide ship together.
