video-lamzac lounger This looks pretty easy and fun- I might have to make a small on - chair size - just to see if I can. Lamzac lounger

Very cool! Easy on a tent floor too. I could see me pulling it out of my ruck halfway through a travel day and taking a nap! I wanna make one too!

Portage Keeper - if you have a plan - let me know - I have a couple of ideas and want to think it through before sewing but it should not be too hard - a big "dry" bag with roll top.

Silnylon or heavier, webbing and clip. Make very long cylinder, fold in half and close both ends with roll and click?

Keep me posted as you figure it out. Even if I don't make one, I am interested in how they made it.

I was thinking on those same lines. I'm thinking that where they fold together the two would need to be adhered to each other - glue in an hour glass shape to create a depressed center. Not sure what they did there otherwise. Two open ends that meet and roll closed as one(?) I'm not going to invest in this. If I have enough fabric for a test run then I'll attempt it. I have some blue w/urethane coating. Because the coating has a strong smell to it I seldom use it for anything else. If that would work then I'd invest in some silnylon and try for the final product. Full width fabric would make roughly a 19" tube. At 7'plus long - 5 linear yds X 1.66 yd width - 8.3 sq yd X 1.3 oz = 11 oz. Maybe better with 1.9 oz fabric (cheaper too) @ 18 oz total?

Other things it could be used for...
Sleeping mat, a huge gravity filter ;), a spare water craft/raft, to float around on the lake...

I was hoping to figure out a chair of some kind.

We could start a new fad and put the Helinox guys out of business if we could figure out a light weight comfortable chair that is not too hard to get in and out of. Might also need a flame retardant.

Bean bag - air chairs. Have a pouch to put weight (sand or small rocks) in to weight the bottom so you don't fall over and it doesn't fly away when you get up to refill your coffee cup.

I was going to try some left over rip-stop and make a small one as a trial. My engineering hurdle is trying to "shape" the tube to bend where I want it and not put too many needle holes/seams to have air escape while under pressure of sitting.

Keep thinking - this may just turn into a mind game diversion but interesting.

OH, new idea - from your "sleeping mat" statement.

Make one long cylinder a little more than the width of a sleeping pad and twice as ling - put flat insulation layer in one half (thin light weight batting) and do the same fill, roll, click idea but sleep on the flat top not the dent between the font and back sections. Sort of like a DIY Exped.

I might actually have to try this. Air tight fabric could be a problem.

Looks like I won't be making one of these anytime soon. Don't have enough of the fabric that I was willing to waste. Plenty of 1.1 oz sil and poly, but I don't think that 1.1 oz is the way to go. I'll keep it in the back of my mind.

I doubt the fabrics you are suggesting (1.1 sil nylon, or your typical
urethane coated nylon)will hold air once a person is on it. Drybag heat sealable nylon would be my first thought of what would work.

I had doubts about that as well. It's one thing to hold out water and another to hold air pressure. I would want something that would hold air for an hour or two and not really serious about sleeping on one overnight. If the right fabric comes along, I might pursue this but at this point it's not on the top of my list.

Ok, you have convinced me - back to knitting and sewing fleece hats for the homeless shelter. Better use of my time.

Though - I do think that Dan Cooke needs to have a weekend class in wilderness sewing and materials.

A guy over on hammock forums did a diy one of these, there were some hurdles to overcome but in the end it worked pretty well by his report, so it is possible.

That's a cool item ! But I'd have a hard time getting it into my REI half dome !
I'd love to try one out ! Might even make a great emergency canoe !
