I have the Summit Bushmaster X4... it's similar to the Cobra but doesn't have the back rest or the bar thing? The seat is very comfortable even without the back rest. I'm a pretty big guy... well, wide anyways. I'm about 5'9" 250lbs and this stand fits me perfect.

The side arms on most climbing restrict shots a bit, and the sumit X4 Cobra isn't an exception. This will make a sitting shot very dificult, so stand up early. The seat slides back when you stand and the platform is plenty sturdy and roomy enough to get a good standing shot.

I tried the stand a few times without the foot rest and after installing it, i don't know how i ever lived without one. That little fold out bar makes you feel like you sitting back in a recliner!

I don't think you can go wrong with any climbers in the summit line.

Good luck!
