From time to tome Aldi have garden furniture, and a couple of years ago I bought a green plastic folding/reclining chair with cushion I think it was £34.95. It is one of the most comfortable light weight chairs. Its sturdy and my wife who is disabled finds its both comfortable and relatively easy to get in and out of.
So much so that when visiting relatives where we know they there won't be enough chairs to go round we take it with us.
Unfortunately, ALdi have not had the same design again, and of course it is a seasonal item- but worth looking out for.
