This Alexander Rose armchair cushion is designed to fit into the seat, providing extra comfort to the ergonomic armchair. This cushion is made using 100% Polyester & is filled with 100% Ultraspring Fibre. It is single piped & comes with ties for securing to the chair. The fabric is resistant to shrinking & staining. We recommend you maintain your cushion in order to prevent the need to deep clean, it is always best to clean any dirt or spills before they become embedded into the fabric. Simply brush off dirt, wipe any spills or spot clean any stains after they occur. We also recommend storing the cushion in a dry environment through the winter months; this will ensure the cushion stays in good condition.
