The Lafuma alloy deck chairs are expensive, but superb.
They are really light and travel well in our rear washroom, wrapped up in old duvet covers. They recline enough to be usable for sun bathing, and also double up as good chairs for placing round an outside table at meal times.
Very comfortable, even for my 16 stone!!
We bought two of the larger sized ones with headrests and two standard ones at the NEC a couple of years ago.
Never regretted it.
