## Customer Reviews

### ⭐⭐⭐⭐⭐ Does what it says!
*by G***R on 29 June 2024*

Important to follow the guidance notes... The individual sections really do 'loft' over the course of 30ish minutes in a warm room.. Then just fit... Note... Give yourself time to do this properly... You have been warned! 😁
