Armchair Engineering?

[SillyOldDufferModerator @sillyoldduffer]

Help! One of those jobs I expected to be easy has gone sour.

My devotion to Armchair Engineering has worn out my single most important tool, a Sedus Office Chair.

Foolishly I thought this would be a simple upholstery job. I've replaced fabric before on a office chair that came apart with no trouble. This one's not obvious because the seat sits in a plastic pan which hides how it's fixed together:

Short of violence I can't see how to take it apart. Most of the holes have nothing underneath. The exception is two holes at the rear of the pan allowing access to a pair of small splined-head bolts (about 4mm diameter). Loosening them has no obvious effect. (I'm nervous of taking them out in case something falls off inside!)

Any advice please?

Ta,

Dave

Hi SOD, maybe its just clipped into place like car door panels are, if so you'll just have to find where they are and maybe make a suitable forked tool to get behind them to pop them out. Just a thought.

I replaced the material on mine which I bought in 1991 for sitting in front of the computer for six years doing an OU degree. I think the original material lasted about ten years and replaced it with some upholstery fabric which still shows no sign of wear.

The base and back plastic covers are actually clipped in place, a b it of brute force and ignorance is required to separate them. I think that they are like most things and not meant to be recycled. I did break some of the clips in taking it apart but it has held together and is used daily for some hours.

Not much help but unless someone has took some photos of one that is all I can offer.

I stripped an old office chair some years ago, the cushion was fixed to a wooden plate which had captive nuts and was removed by undoing four (I think) screws from underneath. The backrest was of very very similar construction.

The wood was hidden under the upholstery, hope I got that right as my knowledge of furniture is minimal to say the least.

Is it worth all the aggravation, bin it and buy a new one.

Select a long(ish) beefy screwdriver and slide it between the plastic pan and the cusion and see if you can lever enough gap to shine a torch to see what holds the two together……

You are clearly in need of a stool softener.

Neil, do you mean 'not so much a repository as a suppository' ?

You are not alone, too many hours on this site has rendered my chair similar.

Looks like Upholstery will need to be added to the short list of skills before too long

Worn out? That's just broken in.

I use this one from Ikea – it's a sort of Gucci swivel tank-gunner's seat.

Roberget chair

It even comes in WW2 German Panzer Grey.

It discourages verbosity 'cause you don't wanna sit on it that long.

Pity it seems to be NLA.

True, but you should see the state of my bottom!

30460 – slip on covers – yes, though the arm-rests make it harder.

Bob Stevernson – 'see if you can lever enough gap to shine a torch ' – good idea, and reminds me I have an endoscope that might fit in.

V8Eng, Howard & Nicholas – the other seat I mended was screwed together as V8Eng describes, but given the lack of access from underneath I think clips are a distinct possibility. I'm confident to try violence now..

Baz – buy a new one – goes against the grain because I'm canny with my money, but I take your point. Depending how unclipping goes, this might be the right answer.

Neil & Meunier – I'm sitting on those ideas!

Thanks

Dave
