Dining chair cushions and Office chair cushions are the 2 kinds of seat cushions available. You urgently need a chair pillow if your dining chair isn't soft enough and is uncomfortable to sit on. Put them up against a rigid wooden backrest or on top of a hard seat, and you can eat so much more comfortably. An ergonomically designed and comfy office chair is essential because most people spend hours upon hours sitting on it. Office chair cushions give you a softer surface to sit on and provide immediate pressure to your neck, back, and hips.
