Hi Marple,
I'd like a new table/chairs also mainly because I want to get away from mahogony and go for teak!
I know where you are coming from about the chairs. The only point I would make about your solid wood chair is that there are a lot of those around without any upholstering, at all, and it makes them quite uncomfortable.
At Christmas I saw a long, dark table in Dunnes Stores in Stephen's Green Shopping Centre. I'm not too sure if had extending ends but it did appear to be quite reasonable. Certain branches are testing out furniture sales so they might be worth a call. They were selling the chairs that you describe with the all leather covering and I think it makes for too dark an overall appearance.
Came across this [broken link removed] on google and it might be worth a browse.
Might be worth your while to e-mail Richard at furniture.ie as he is has been very helpful to others on AAM and perhaps he might be able to point you in the right direction.
A few of my favourites for furniture are:
[broken link removed] - expensive though
Dublin Furniture Store, Capel St., D/1 (mainly teak tho)
Furniture Designs,Old Bawn rd, Tallaght, Dublin 24, 4515326 - they have a website but I can't find it at the moment.
HTH. P.S. No connection with any of the above companies just a shopaholic
P.P.S. Wouldn't be my choice but what about = €639.95
