The Wing Skid Polypropylene seat shell is styled with a castellated edge detail that flares out towards the top of the back for added support. The horizontal lines running across the seat & back accentuate the contours. The seat sits atop a chrome steel skid frame that allows this version of Wing to stack 4 high. The chrome frame has black feet along the bottom edge to protect any floor surface the stool sits on. There are 9 seat colours to choose from or why not try a mix of colours to brighten a neutral interior. There is also a matching high stool.
