Pair of folding cinema/theatre seats (Rowde SN10)

This is a restoration re upholstery project ! The chairs join together are complete , really nice curved wooden backs the seats are sprung but all the original covers are perished but there to get pattern from . I was told they came from a theatre or cinema in pewsey ??? I have held on to them for years intending to re upholster myself but I never have had time so if anyone wants a project for 2024 ???
