Wardrobe interiors

[Simpo Two]

I have a built-in triple wardrobe that's been unchanged for decades and is about the only part of my house I haven't made nicer. It might be time to take out the s/h pine chest of drawers and sheets of white MDF and replace it with something classy-looking, eg walnut/chestnut look with drawers, shelves and rails. Can anyone recommend a place that supplies configurable quality interiors please?

The only place I have found so far who do worthwhile interiors are actually Ikea, I'm just not sure about the quality of the unit itself as I haven't seen one in person yet.
