I wanted to share these pictures with you guys because there are not too many sites on the internet dealing with home made telescope observing chairs.
I came into building the chairs from absolutely no woodworking or ATM or DIY experience. In fact, this lybar chair was my first ever DIY from scratch project. I cut the wood myself using basic hand tools, and i did not have enough money to buy power tools.
So lets get started shall we? Please give suggestions/opinions as they come to mind.

Notice that my particular chair is a flip on the original denver design.
I made it so that the chair itself is removable from the entire system. The only thing keeping the chair from being removed completely is the string that keeps both legs attached.

notice that this denver chair only has 1 friction strip. It is a rubber type strip held on by rubber cement.
Where do you suggest i add friction strips to make the chair more stable? My biggest problem is that it comes crashing down when there isn't enough pressure on the existing strip.
What about using rubber vs friction strips? is any superior? what about using both?

Here is the lybar chair...I love this thing. I still use it despite having the denver chair. It is far more stable.

I sincerely hope this has helped someone. I assume this was a worthy contribution.

Been thinking about trying to build one of these. In terms of the denver chair, have you considered adding foam trim around the clamps on the edges of the seat? I mean the kind that they sell in small squares, about 1" square, with generous amounts of adhesive on either side. I'm thinking that applying one side of such a thing to the chair, all the way across, and another side to a new strip of rubber, would allow maybe slightly more friction to hold the chair up. The foam would deform ever so slightly around the chair legs when you're sitting in it, and kind of "grip" them.

Brooklyn The mods I saw online and right now I dont remember where was to keep it from slipping down you get a bungee cord and attach it to the bottom front of the seat and attach the other end to the bottom of the front leg and the downward pull of the bungee will in turn keep the pad on the back of the seat in contact with the frame and in therory keep it from slipping it will make the non slip pad yp installed act like a brake shoe.I hope this helps and you understand what I am saying.

I found it go to this site and look at the pic you will see a small bungee under the front of the seat

Wow great idea! *BLEEP*, that is so friggin cool! I didnt even think of doing that. 
And yes, as you can see from the pics i do have a bottom hook that i can attach any bungee to.
All i have to do now is add 1 friction pad to the other wood to wood surface (you can see it in the pics its opposite and lower than the rubber pad.
So im guessing i will have to drill another hook into the bottom of the chair.
Thanks so much!

By the way...look at that picture of the lybar chair.
See how the wood says scrap on it? I was surprised that bottom of the bottom wood was good enough to build a chair. I dropped the lybar chair in that photo down a flight of stairs just for the heck of it, and it didn't even get bashed up!
There are three screws holding each wooden plank to the other. There was no wood cement or gorilla glue used on the lybar chair, its 100% screws.
Amazing how strong garbage wood can be eh?
By the way im 230 pounds, 6'0" in case you were wondering how much these chairs hold up. That is why the lybar chair really impresses me, I put ALL my weight on it and it doesn't even budge. I can jump up and down on it.

Thanks for sharing your pictures with us Brooklyn.

I agree I used 3/8 lag bolts and some wood glue on the T brace was the only place I used The Glue.As for the scrap wood I have a little wood shop and yes it is amazing what you can do with someone elses scraps.I think you did a super job Brooklyn.And as o1d dude says Deck screws are forever thats no joke I buy them by the big boxes ya never know when they will come in handy.

Brooklyn that denver chair you made is a beautiful chair. It is too pretty to take out and get dirty. From the photos it looks like a showroom piece,very well done.

THe Lybar chair is great- I never thought of 2x4s- I was search the garage for some 1x5s to build mine- GOnna grab some 2x4 scrap on the way home (or even better- some 2x6- the local building truss company always has some 2x6 scrap in the "free wood" piles!)

Yea i had some help with the denver chair, professional type help from people in my astronomy club! 
Youre right, by comparison the Lybar chair looks like the older uglier cousin.
For the lybar chair, i changed the original design...
The seating heights are 12", 20", 24" as you can see from each of the 3 pictures. The original lybar chair was only 12, 16, 20. I wanted an extra 4"
Also, note the vertical added support column added in the middle. I was a little scared of sitting on what is basically a simple bookshelf, but oh my god i cant believe how strong this structure is.
I didn't even buy the scrap wood that was made into the lybar, i found it all in my garage! it was leftovers from the contractors that worked on my house. Cool eh?

Great looking chair! I picked up the plans to the original Denver chair and plan to take a crack at it, although I'm thinking about making it a bit taller. I haven't worked with wood since high school shop class back in the '80's, but it looks pretty manageable, lol.
