I've had two lovely walnut-coloured solid timber wardrobes installed by Impressive, and am in the processes of obtaining a third one. Our home is a 100+ year old victorian building so the floors are not quite level. The walls, ceiling and floor of the rooms don't quite meet at 90 degrees and some of the walls are even curved. The ceiling is also unusually high. We were skeptical that wardrobes could be snugly fitted, but they did it! The installer showed up on the day and cut the timber to fit the walls that had warped with age. Both wardrobes were installed in one day which was fantastic. They sales rep themselves are exceptional with the fine details, e.g. colour matching hardware to the materials, colour matching existing colour schemes in your home, adjusting sliding doors to suit a non-level floor so they don't slide open, etc. While you can get an accurate quote from them in store if you supply your measurements, they will always insist in visiting your home to ensure that nothing is overlooked. As you'll be able to see behind their showroom, they actually make their joinery on site so our detailed sliding doors were custom fit.
I will post follow-up review once we get our 3rd wardrobe in, and we'll also see how easy it is to get one of the doors adjusted under warranty at no cost (it has a preference for sliding leftwards unless pushed firmly closed).
