The Tasia Swivel Lounge Chair from Sunpan features an exposed birch wood frame that creates geometric detailing around the upholstered seat. It features a 360-degree swivel, allowing full rotation from a stationary birch base. Solid birch wood forms both the visible frame and the structural foundation, with natural wood grain and color variations appearing throughout. Fabric upholstery wraps the cushioned surfaces, and an included pillow provides additional back support. The exposed frame design reveals the chair's construction while maintaining upholstered comfort, and the swivel mechanism adds functional flexibility within a space.
