4 cushion pads for chairs (Henleaze Ward BS9)

3 are labelled Ritva, from Ikea. All labelled as washable at 40 degrees. 3 of them are 40 x 40 x 7 cm (that's 16 x 16 x 3 inches). The 4th one looks a little bigger. All need a wash and are not in brilliant condition. Please tell me if you want 1 or 2 of them or all 4. I am offering them for someone else so no idea how old they are. Collect from Kellaway/Horfield Common area. Please tell me collection plans when you reply. I've taken a photo of each side of each cushion.
