Just thought I'd add these in to show how simple a bench seat base can be.
The cushion is a sheet of marine ply soaked in varnish with a closed cell foam pad, and all covered by Mrs Nasher in grey vinyl. There are blocks of timber added to stop it sliding forward.
The enclosed Transom on 'The Nashers Revenge' makes mounting the backrest easy of course.
It's held upright by a couple of straps and clips on the sides near the top.
