Hi All,

My daughter is getting a hanging chair for her bedroom.Â* It is
essentially made of ropes which end with a single loop at the top to
hang it from.Â* There are no other fittings with it so wondered what
the best way to hang it from the ceiling is?

Assuming I can screw it into a joist where she wants it I have the
following questions
1. What fitting to use?Â* Having had a look in Screwfix was wondering
if something like these would work
https://www.screwfix.com/p/magnodur-...5-x-15mm/527jf
https://www.screwfix.com/p/easyfix-z...-10-pack/15851


or anything better?
2. If I end up with a plate type thing (such as the first link),
assume I will need to cut the plasterboard to ensure it is on the
joist itself to avoid the ceiling cracking?

If I can't get to the joist now what are my options? 3/4" ply screwed
between 2 joists (either on ceiling or between the joists) and then
what fitting?Â* Assume I will need a much broader plate type thing with
several screws to distribute the load?

Sense this is all fraught with danger and the fitting is many times
more complicating than buying the thing in the first place

thanks

Lee.

My view is that joists are not designed to take point loads this way,
the floorboards normally spread the load.Â* Maybe that's over-cautious.

Is there a loft above which you can get to?Â* If so, some 3/4 ply used
atop some joists to spread the load is the way I'd go.


I tend to agree, also it very much depends on the size of joists and how
close to the end you are. In Victorian houses the joists are typically
very much more substantial than required. Is there a habitable room
above? This may well have bigger joists than a loft. If not, and if it
is a modern house (by which I mean less than 50 years old) then I would
definitely be going into the loft and trying to engineer a support plate
spread over two joists. It also has to be said, how heavy is your
daughter (or her friends).

And, at the risk of being over-personal and/or vulgar, might it ever
have multiple occupancy?
