Down the years I've had quite a few chairs (all I've still got) from the garden fold-away. Used that for years before I bought a purpose built chair. Since then I've had 4 purpose built chairs. First a "no name" with square tube steel adjustable legs with push-in buttons to adjust it.
That fell out of use because of the buttons being fiddly.
Then I bought a JRC Specialist Chair. Bomb proof, great chair, sprung plate adjusters, problem was, it was made from round tube steel and came in at a weight of just under 8K.....To bloody heavy for long walks on the river.
Then came the Fishrite Xtreme Lite, good chair extender legs were a bit to short. This chair was light at 3.5k
Then the current chair I've been using for 5ish years the JRC Specialist X-Lite. Leg about 2 inches longer folded up, giving 4 inch longer when extended than the Fishrite. Can't fault this chair, other than the inherent fault most chairs have, the front legs fold over the back. Allowing them to fall down and hang out when the stiffness of the folding joints work loses.
On the Fishrite chair the back fold down over the front so that problem is eliminated.
Now it's my opinion that for a river chair, even if it's well padded, the price shouldn't exceed 50 notes. And any company asking more are having a laugh and making you pay the rest for their name! Now if you don't mind giving them 30 notes for the privilege of advertising their name, then fine, but it's not for me and seems arse about face. They should be paying us, not the other way about.
Mud feet coming off? Well get the drill out, pull the mud feet off, drill right through both parts of the ball joint, replace and put a nut and bolt through it. Problem solved!
