5 Contemporary Designs... & my 1st impressions: 1. I'll stick with a traditional papasan, thanks. Less likely to get poked where it hurts. 2. Wishing had pool noodles right now. Or a life sized Gumby. 3. Oh that looks just like my computer chair! Sans the cage. Maybe I need that part so the "chair" stops mysteriously rolling into other rooms. 4. Whaaaat? *reads article's description* Ohhh! 5. No.

Hi Sue! Have a look here in the products section - http://www.houzz.com.au/photos/products/query/swing-egg-chair/nqrwns There's a few swing chairs by some big brands that are in Sydney (Harvey Norman, Mitre 10 etc) !

I really like the idea. But you need to see whether the height of the chairs is in sync with the table for comfort of diners. But great use of opposites.

It's a pretty substantial beam so a 10-12mm hole for a bolt through the flange will have little if any affect. Certainly no worse than cutting holes through the web for running of plumbing and electrical's, which is where the majority of a beams strength is. We secure cabling to steel beams with holes drilled into it so shouldn't be an issue. The difficult part may be drilling the hole (for some). It probably the hardest one to do.... It's overhead and it's steel, so a nice sharp drill bit is definitely needed as is safety glasses, ladder, etc. The swarf (drilled metal) is sharp as hell and usually hot during the drilling so again safety first. Sweep up any remains as it cut's little bare feet like razor blades! I dread drilling overhead with a handheld electric drill and the bigger the drill bit the worse it is as they can grab when almost all the way through the hole.....and I've done it thousand's of times......
