What are the dimensions of this cushion?

Our seat cushion is in XL size, with dimensions of 19x17x4 inches.

Why does this cushion feel uncomfortable when you first start using it?

Because it's designed to improve your posture and reduce pressure points. Most custormers find they adapt to the new support system within 1-2weeks, enjoying significantly improved comfort and long-term benefits.

Why does the cushion feel so firm when I just received it?

Cold weather during shipping can temporarily harden the sponge. To restore its softness try 2 methods 1.Let the cushion sit at 20°C(68°F) room temperature for 4h. 2.Place it near a gentle heat source （like a fireplace) at 70°C(158°F) for 35 mins.
