We have for sale approximately 15 of these tree climbing high seats that came in as part of a buy out we did a few years ago - they went into our storage unit and were just found!
They are all in A1 new condition thought the boxes are dusty. We don't honestly know anything about these other than that we sold a few for £50 when they first came in to a couple of tree surgeons who wanted them for deer stalking.
We would guess these are probably best left to people who know how to use them.
£50 collected or £75 posted due to size & weight.
