Torso-sized Air-mattress proposal on 04/18/2009 22:49:39 MDT Print View

I have a proposal/challenge:

Who: Anyone who thinks they have the ability and may be interested in a plush, torso-sized (~35") air-mattress.

Why: Because no one makes one that I am aware of and it has the potential of being around 5 oz. to 7 oz. in weight, depending on the pad used.

How: By cutting a Big Agnes Clearview Pad in half and seam welding each of the two halves "open ends" back together with the appropriate chemical bonding agent. The side that lacks a valve will either need to have one attached using a replacement valve kit, or we could try leaving a small hole in a corner, then using a lightweight roll & clamp closure mechanism (to be sourced).

Where: I am willing to purchase a new donor pad and have it shipped to your place so that you can "perform the operation." In exchange, you get to keep one of the pads and we both get to beta test.

When: Whenever we have some time, eh? Actually, the main reason for this post is that I am building a house right now and don't have the time to spare to tinker, so I'm hoping someone else might be interested in undertaking this project.

If anyone has tried something similar and would care to comment, that would be excellent. I am not certain of the feasibility to effort ratio of this and would appreciate any input.

I don't want to sound rude, but I think it's time for you to step away from the scales, and go hiking.......you're trying to save what? 2-4 ounces?

Yes, I hear you and concur.

Unfortunately, it will be a couple of months before I will be able to get out (I promised my wife I would finish building our house first - reasonable enough). So, I have to throw these ideas out there in lieu of the beckoning wilds, or might realize my deprived status. Actually, I really enjoy working on the house and considering our current house is a little to "UL" for a family of 5 (+ one more on the way), we're really looking forward to have a place for both kids & gear.

Then we'll have good reason to celebrate... and maybe some lighter pads too!

"you're trying to save what? 2-4 ounces?"

In a forum focused on lightweight hiking where many cut down toothbrushes to save weight, I don't see this idea as unreasonable, or the idea of saving 2-4 ounces without merit.

I don't know if I'd make one myself, but saving weight and retaining comfort and function sounds good to me.

Also reasonable: when so many of us have already cut the pounds off our packs, ounces are the next logical extension of our work. Taking a few ounces off here and there will eventualy cut a pound. When you get to SUL packweights, that two to four ounces may be a significant percentage of your overall packweight.

Also, take a look at getting a large one of the Neoairs and chopping it off. Then you can have a wide pad, at your desired length, with no weight penalty (hat tip, William Pucket).

I'd give it a go, but I don't have the time right now. I have a full length Neoair that I will be chopping up, but I have a trip planned in a couple of weeks so won't be able to do it until afterwards. I've never seen a clearview but you might try to get someone to just "cut" it in half with a thermal impulse sealer (think packaging machine) that will melt the top and bottom together. Then cut the bottom off and your good to go! Whether or not that effect the baffles/inflation I am not sure.

I think Joe was just making sure that I don't neglect the 'reason' for lightening up. Cheers!

Steven: I'm glad to hear that you're taking the knife to the NeoAir! I ordered the short, but of course, that is where the idea came from and is ultimately intended. Keep us posted on that and good idea on the thermal impulse sealer...any idea where to find one?

His advice is the best so far, go hiking! I can't wait until my schedule clears up enough to get out again. Besides, I've got gear to test! ;)

Aaron, I should first state that I am not sure a thermal impule sealer will work, it was just what comes to mind when I see any type of plastic sealed. Other then packaging companies, I am not sure of where else to find one. You'd have to search/call around. I've got a little one that I plan on testing the neoair fabric with, but I would need to use a big industrial one if it actually worked.

Why? OK, you might need to make several welds along the end, but wouldn't that work?

Roger,
I could probably get a seal, but it may not look too pretty. The problem is that my sealer has a hinged hot bar on it so it may be tough to get the middle seal done. I'd have to see what the length of it is...actually, i think it may be 12 inches or so...that would work, but I won't try until after my next hike. I don't want to buy another pad before I even use this one!

seam sealers on 04/21/2009 06:11:53 MDT Print View

Seam sealers are used to close plastic bags. They are found in packaging supply companies.
