Foam Cushion (West Bridgford NG2)

As advertised on TV. It is a cushion that comprises two foam bloks that are glued together (memory foam/standard foam?). Bought by my mother (90) but she didn't like it. It can be used on a firm seat to make it more comfortable or under knees when gardening. It like new as it has had little use. Mother thinks it was about £25 when she bought it.
