The idea behind our Tensa4 stand is so simple that inexpensive homemade versions are irresistible. There have been several dozen DIY builds shown online since we showed our prototype in October 2017. They can be hard to find in the ephemeral jumble of social media streams, with their poor search features, and build details are scarce. To help fix this, we present below three builds that seem to us especially good: simple, cheap, and not requiring fancy tools or skills to make.
Dane’s bare bones tensahedron
One of the earliest builds is still startling for low cost, at $21. Poster Daneaustin3 presented it in November 2017:
In his own words:
3/4″ EMT conduit with 220lbs in it. I used steel cable to hold the conduit together.
4x 3/4 conduit cut to 95″ (fits in my 8′ bed truck) $4.25 ea
4x 1′ steel cable $.36 per foot
4x cable clamps $.63 ea.
Total cost $21
Travis’s segmented fence top rail tensahedron
Travis Hodgson (aka fivefreds), wasn’t the first to use fence top rail instead of EMT, but he did put up some good photos. Top rails are heavy and strong. These come typically 10′ long with one end swaged. Chop the pole in half for easier transport, and you can insert the swaged end into the middle to rejoin, securing with a pin. 10′ is more than long enough, so you might chop 3-10″ further off the sections.
Travis’s pole connectors are super elegant: continuous loops of Amsteel rope pushed through grommeted holes drilled in the pole ends, and then looped over the pole ends to secure.
It’s important to assure that the holes in the poles don’t cut the rope used to connect them. Grommets are a good idea, because steel can be hard to de-burr adequately. The coolest grommets I’ve seen are short pieces of copper tubing inserted through the holes and hand peened smooth:
Mike’s telescopic EMT conduit clothes line tensahedron
Mike Jones’ build uses two telescoping sizes of conduit to allow the poles to collapse to about half the full length for easier transport. Multiple stops make the poles adjustable length. The joint is near the middle, the weakest part of the pole, but 1″ steel conduit is pretty strong, and the overlap generous to take up much of the slop between EMT sizes.
In Mike’s words, edited:
Maximum length of each pole is 9’6″ and collapses down to 5’4″. Materials added up to about $50 provided you already have tools, hammock setup, and some 550 paracord.
- Two: 10′ x 3/4″ EMT
- Two: 10′ x 1″ EMT
- 550 paracord (used to attach the two points that touch the ground together. As well as button knots on a loop, like MeyersTech ties, to run though the 3/8″ holes attaching the poles together.) This will likely be replaced by Amsteel or webbing over time.
- One: 1/4″ PEX tubing (I found a 5′ length to buy but I only needed 1.5″ or 2″ per hole in the EMT to create a bushing so the paracord is not cut by the EMT. I had to heat the end of the PEX over a candle to flair it out.)
- Various hammock straps and lines to attach the hammock and tarp
- Eight: Rubber Leg Tips. I used 3/4″ tips for the 3/4″ tubing but I would likely buy 1″ tips if I make it again. Then I used 1-1/8″ tips for the 1″ tubing. Then I placed 1″ and 1-1/4″ fender washers inside the rubber leg tips so the EMT tubing does not cut through.
- Four: 3/8″ x 1-5/8″ Round Wire Locks. These are to secure the telescoping poles at various lengths while in use and in the compact mode for transportation.
I used the 9’6″ set up for my 12′ tarp, and it worked great, but a shorter pole length would also work. If you keep the two poles that touch the ground at 90° to one another, the following table of pole lengths will be a good estimate of ridgeline (hypotenuse) length. There is plenty of wiggle room here, but it gives you a starting point.
Pole Ridgeline 9.5′ 13.4′ 9′ 12.7′ 8.5′ 12.0′ 8′ 11.3′ 7.5′ 10.6′ 5.5′ 7.8′
Want another EMT version that packs even smaller? See US soldier Kamileon’s build.
In addition to steel, DIY tensahedrons have been made from wood, bamboo, fiberglass, aluminum, and carbon fiber.
The pole material determines the necessary diameter for enough strength. For about 300lbs in the hammock, 3/4″ is adequate for most steel including EMT conduit. 1.5″ is likely enough for aluminum. Wood and bamboo can be very beautiful, but as irregular natural materials, it is important to select carefully: 2 inches is a prudent minimum for clear wood (no knots, straight grain) or structurally sound bamboo.
The poles must be joined at their ends into a diamond shape, with none of the joints having fixed angles, but instead floppy, permitting the poles to assume any angle, and to rotate at least several degrees. We favor rope loop connectors as simple and field serviceable, but various combinations of hardware and even lashing can also work. Avoid using hardware that can put bending moment on the poles when loaded, such as eye bolts protruding from the sides of the poles: poles should be in pure compression, lines in tension.
Joints along the poles can be points of failure, especially near the middle. Best to use either very strong materials, split into an odd number of segments, or both. (Tensa4 poles are divided into 7 segments, with the largest diameter in the middle).
Why are we telling you this?
As a company, our focus is on products offering value beyond what people can easily make for themselves. Why promote cheap alternatives to buying our stuff?
Apart from us doing all the work, burdening nobody with the task of reading long blog posts, the special value of our Tensa4 stand is how we’ve made it pack so small and light: carry-on airline luggage, easy to pack on a bike with a motor or not, in a subcompact car, Cessna 150, kayak, or even a backpack. We realize that this amount of portability isn’t worth the price to everybody, especially large families seldom far from large vehicles, scout troops, extremely cool small national armies, or people who want only a home solution. We can’t compete with your local hardware store for basic poles if you’re willing to contribute labor. We truly love helping people get off the ground with hammocks, especially where they couldn’t without this design.
Meanwhile, we figure the more people embrace the basic design, the more interest may turn to our packable dialed-in version, in 28 segments of custom made telescoping aluminum, keyed and anodized, not available at Home Depot. Quite a few of our customers, in fact, made one or more stands themselves before buying Tensa4.

Tensa Outdoor, I love you even more!!!! BECAUSE you posted low cost diy options. I reeeeallly want a tensa4. But current finances are restrictive. Our boys are very active in scouting and with an injured back I was afraid I was going to have to give up camping with my kiddos. (Tent/ground sleeping was agony.). Then I discovered hammocking and OMG OMG OMG!!!! I’m back in the saddle again!!!! I. Can. Do. This!!!!!…. except when we don’t have trees!!! Which has happened 2x since we began hammocking!!! You are on top of my wish-list!!!!! Thank y’all for supporting people getting out and active!!!! I’m going to decide which of these will work for me and attack it next week!!
Thanks for sharing all this information. I’ve made recently my own tensahedron, you can check it at https://www.2pe.org/ideas/2019-08-22-tensaedro/
It’s a bit bulky but works. The previous one with slender tubes couldn’t put up with my weight (only 56 kg).
It would love to buy a Tensa 4 but for now isn’t possible, maybe in the future if you start selling in Europe. You’re on my whises list.
Yours is the most elaborate DIY I’ve seen, 5 telescoping segments per pole approaching our 7. Thanks for sharing.
[…] plan is to copy "Dane's Barebone Stand" from the tensa website (which is also shown here on hammock forums). I'm a bit nervous since there's not […]
If I can get a carbon fiber one that is light enough for backpacking, things will get interesting.
My first functional prototype was in carbon fiber. Our present Trekking Treez product is far lighter and less expensive than would be a carbon fiber tensahedron of similar weight capacity. There is a carbon fiber tensahedron made by a German company, optimized for transverse hammocks that put less strain in the poles. Note 153-lb weight limit for gathered-end hammocks: https://crosshammock.com/en/shop/carbon-tree/.
Do you think 1/2″ EMT as top half inserted 12″ into a 3/4″ EMT would be enough strength?
1/2” is smaller than I’ve heard attempted before. I don’t know the answer.

In the comments the author states that he is using those dimensions
Yes. I’ve done it. I weigh 210 lbs.
Well, seeing the work and shopping and designing and building a DIY version has convinced me to go shop your website. I’ve been working on using an insulated pad instead of an underquilt so I could go to ground if there were no trees. But – maybe I don’t have to if I bring my own trees!
Yes. I’ve used it for years
[…] Another version or you can say very similar to the previous stand plan for camping. The similarities while picking up rope, stands, yet in a very geometrical design. Instead of wooden boards like in previous models, depending on the thrive for symmetrical stability which you will use to raise a fabric hammock from the ground, either you can say cradling the hammock. The 4 stands keep it balancing, as well as the suspension with precision, which raises the possibility of drift off except for any fear of falling feeling. […]
