Hammock in the garden

The idea of lazing in the hammock, at home, appeals to me.
However, my garden has no trees, and there are no strong and suitably spaced fenceposts, either, so I was thinking that one of those free standing hammock frames might be worth a try.

Has anybody done this, and have any advice?
Length between suspension points would seem to be the obvious thing to watch for...

We've got fruit trees so a bit easier, have even bivvied - obviously doesn't count for BAM.

As ever with hammocks Shug Emery on YouTube will have you covered. Here's his channel - https://www.youtube.com/@shugemery. Tensa poles are generally regarded as the best but I'm not sure if there's a UK distributor.

I've got a hammock in the garden - it is indeed a lovely place to be on a sunny afternoon. I've put rings on the uprights of my covered deck to hang it from now, but it came with a stand of sorts: each end has two lengths of wood with an eye bolt through one end so they open out into an A-frame. The hammock hooks to the eye, and it's tensioned by a rope attached to an anchor that screws into the ground (very similar to those dog tethers). It all folds up pretty compactly for packing away. Would be very easy to make one.

Edit: took a little bit of searching to find a picture - they don't seem to be that common

Thanks - I've seen those A frame arrangements, but I don't have the room for the guylines, which is why I was interested in the freestanding frames

Ah, yeah that arrangement does need more space. Is there anything (e.g wall) you could attach one end to?

One problem with attaching to a wall (of any material) is that generally they are intended for a downward force, i.e. gravity acting on whatever mass is above, sticking an anchor into brickwork/blockwork and exerting a horizonal(ish) force on it might not be the best idea.

The recommended angle of a hammock's suspension is 30deg* from the horizontal, doing the maths means that each end has roughly the same force acting on it horizontally as the weight in the hammock. If you weigh 80kg then there'll be 80kg of force at each end pulling horizontally towards the centre point of the system. The shallower the angle of the suspension the greater the force - in theory if your hammock was strung perfectly horizontal there'd be an infinite force acting on the wall :shock:

*for 30deg form a pistol with your index finger and thumb and hold your index finger horizontal, the imaginary line between the tips of your finger and thumb is roughly 30deg.

Thankfully, no - especially considering the post by @whitestone

I’ve got one of these
https://www.amazon.co.uk/gp/product/B00 ... =UTF8&th=1
It’s great, easy to put up and stored in bag so I take it when camping in van.
Really discounted today as well!

I think you might need to check your working there Bob :wink:

But it's a fair point... Although with the right fixings and application, I'd be happy to hang off a brick wall in good condition.

I’ve seen somewhere, a pair of tripods - sort of similar to an easel - that support a long rail in the V’s at the top. The hammock is stretched out but tied to the rail near each end. This means that the tension of the hammock creates a compressing force on the rail, so doesn’t pull the trestles/easels together and doesn’t need further anchors.

The designs I saw used 3x2’s that would fold up for storage. I don’t know how they got around the 10/12ft stretcher pole.

I can’t seem to find a link, sorry.

Head spins in a tangle of vectors.... I think Bob is correct as the horizontal force needed to pull a string enough so that it's horizontal, despite supporting a weight, will tend to infinity.... or something...

I was actually thinking of doing this myself, my thought was my garage wall (well bolted together concrete panels, I just need a suitable anchor,) and a fence strainer post concreted into the ground. Or even a length of scafolding tube.

Sounds like a Turtledog design. Forgive the spelling.
Hammock forum will have plans.
I made one a good few years back out of easily available lumber and hardware. Cost about £20 and folded away when not in use.

Ha! I didn’t imagine it then?

I'd have thought any pair of A frames with a top rail using those 3-way metal sockets would do it. Similar to the 'bike weigh' frame at WRT or pub garden swing/slide type frame.

Very sturdy frame, and seems well made - will be eager to try it, tomorrow.

The one linked to was half the price of the other colours, for some reason - but has now returned to full price, so quite chuffed.

Thanks, v much

So, I've just assembled the hammock and am very impressed.
There are just 4 bolts (with knobs, for hand assembly) required to assemble the frame, and 2 hooked bolts for attaching the actual hammock, so it can be put up or taken down in just few minutes.
The hooked bolts can be attached at various heights to adjust the height/ tension of the hammock.
The hammock has lots of individual cords, so distributes the strain evenly, and the loops that attach to the hooks have reinforcing "thimbles" made of metal.
It all packs away into a very neat canvas bag, with handles that have been attached very well.

Excellent build quality and very comfy - just need to decide if I should allow my (very eager) cocker spaniel to share it
(It may end up that he won't share it with me😉)

Not sure I'd pay the full price, but at 50% off, it was value for money

Glad you managed to get one at that price.

They’re brilliant arent they! Let’s hope we get decent weather this summer so we can use them!

You generally want a hammock to have quite a bit of sag. From hammockforums.net the starting point is to have the "hung length" around 83% of the length of the fabric. This gives you enough sag that you can lie flat on a diagonal. I think I have mine a little less but it's a bit like tyre pressures - there's guidelines and what works for you. Most people attach a ridgeline between the ends of the hammock once they've got the sag dialled in to make setting up easy as you then can't overtighten the hammock.

If you have the hammock too tight you put a lot of tension on the material, again this increases markedly as you approach horizontal. There's one of shug emery's videos where he's talking about sag and sets the hammock at about 15deg and tears the material just getting out of the hammock.

Sounds like a "clew knot" - something that US navy personnel used to use a lot.

Even if you don't get into hammocking it's worth getting a copy of "The Ultimate Hang" as there's lots of tips on getting the best out of a hammock.

Ok, am full of cold, so the maths lessons above are beyond me...

I've got a freestanding frame thing, and a cheap as chips nylon hammock with carabiners.

Tips?
It certainly does if you forget not to park your bottom further in the middle or down towards the foot end than you'd think. Quite amusing that, should be done at least a couple of times a year, especially with a cup of tea or elaborately prepared plate of food in hand :lol:

I find this one doesn't sag quite enough to comfortably sit up to read say or drink the cup of tea (once you have stopped laughing, checked if the neighbours were watching when you fell out, and you've recovered your decorum and got back in), and for reasons above you can't just sit near the top to get that right, but I get around that with a few cushions.

Also mine comes with S hooks each end, which are loose and I lost them during the first winter I had it, so worth taking out and putting somewhere safe if storing away in winter, or else risk bitter disappointment on the first sunny day of spring...

Enjoy

Has a very nice 10 minutes, earlier but have put it way, for now - until the weather becomes more predictable.

We got one of the Amazon hammocks for the back garden a couple of years back now. I’ve spent many an hour in it with a book, often with a kid for company. I think if I was going to spend a night in it though I’d invest in a underquilt
