Essential item for bolting routes
For anyone spending extending periods hanging on the wall (eg bolting routes) this item is ESSENTIAL. It removes most of the pressure off the back of your legs and allows you to work at height for much longer periods than any harness. I clip mine in very short to the biner attached to my GriGri which allows easy movement up and down the rope. Worth its weight for sure. If I were to make a any improvement, I would suggest that BD add clip in loops near the top of the triangle part of the seat so users can clip in short directly vs having to use the ratchet straps. That way one could remove them and save even more weight.

Fear hanging belays no longer
Is it a luxury? absolutely. Will you dream about it when you're at a hanging belay and you forgot it in the car? yes. Not only does will this chair save your butt, it will also save your belayshionships when you aren't yelling at your partner to go faster.
Lightweight and Comfy Wall Chair
Turned Misery into Comfort for belaying those long aid pitches where no ledges were available to stand on. I hope BD continues to make niche items like this for climbers approaching all different styles of climbing.
light and relatively inexpensive
You can make your own, but it won't be as light, comfortable or useful. It's really light, fits in my haul bag and offers a great rest when brushing routes. I attached a nylon daisy to keep the tools attached.
This is NOT safe to use as a Bosun Chair
For a brand with credibility to market such an unsafe product , without explaining that you also need to use full climbing harness at the same time is completely irresponsible
Fantastic but wish the back rest was larger
Took this on Final Frontier at Fifi. Absolutely essential and a total game-changer on that route, but the back rest could be a bit larger for comfort reasons
Generally great but needs gear loops
I'd echo everyone's comments and only add this review to emphasize the usefulness of a few gear loops. That would make it about perfect.
Leg saver !
When repairing routes - this is a leg saver! You don’t lose your blood supply to your legs and it is super comfortable and safe.
Chair
Love it but they should had daisy chain on it so you can clip you stuf. I use it to bolt some route hand it way more comfortable
