What padding is best for a cushion?
Other may be the hairs of other birds. About the cushion, the landlord will choose what price. Personally, I think latex is good and it's very comfortable to use. But more expensive, usually used for mattresses (high-density) or pillows.
Just put some better cotton on it! You can sell it where you buy a cross stitch!And it's a cushion that you can see with your own eyes! Will rely on relatively reassuring ah!
