I've got a few but my favourite is one I got on specials bin in Anaconda for I think $30 about three years ago. I only got one because I thought they were probably crap, being an Anaconda special... I've been looking for another one ever since.
- It has Aluminium tube frame - lightweight, no rust
- Folds flat
- Back support it good and high enough to support shoulders.
- Stainless steel hex bolts on moving parts means some scope for fixing it if it breaks
- Plasticised mesh fabric rather than padding (well one padded section under knees) - still quite comfy, add my own liner (my sleeping bag) when it's cold, water just shakes off if I leave it out and it gets wet rain or due
- Fits nicely upright in the foot well of the rear seat (well room for two of them really)
I've got others - a pair from Rays Outdoors own brand (Wild Country) - also flat, these ones padded and adjustable rake, steel frames, riveted.
