Hi Sally, it is incredibly frustrating when popular furniture items remain out of stock for such long periods, especially when there is no indication when these issues will be resolved.
I am not even certain whether the Toulouse Single Wardrobe will be restocked or not and I doubt anyone at Dunelm will be able to give you an answer since it is their policy not give specific dates in these circumstances...
This is what they say:
Unfortunately, we cannot give back in stock dates on specific items at this time. We often continue to show out of stock products online so that you have access to the product details, for when they are back in stock.

The reason that retailers are so non-committal on re-stocking is that they depend on supply chains that are not 100% reliable.
Sorry I was not able to help you on this occasion but please get back in touch if there is anything else I can do for you.
