I must say, most garden furniture here is not expensive at all, compared to Europe that is... Teak wood finds it origin here, which makes it very affordable. At all garden centers there is quite some choice to pick from. Upper Thompson Road has a few garden centers, but this weekend I visited one at New Upper Changi Road, after Bedok south avenue 3. Tey have a good range of teak and other tropical hardwood furniture for very good prices.
But for even better deals, just go to Ikea at alexandra road, beats all prices....
