I would advise against IKEA, I used the designer, the end product is not good, he made me waste so much money on wasted things, and it is still not finished from months ago, they and the firm they subcontract to, don't want to fix everything, they gloss over most of the issues and only want to fix the odd thing, all they want IKEA and the fitting team is to take your money, they don't care about the quality of the product you are left with, if it is functional, and I have been trippng over spare things for two months now, where they have not made an appointment with me, though someone turned up one day unannounced when it was inconvenient.
My advice hold back the money, and don't sign it off, no matter how much they bully you. I am glad I didn't, as I guess eventually they will want the money and it will be the only way to get functioning drawers that open, and sit properly and the job finihsed, including the decorating in another room due to them smashing in the wall because they didn't use the rails, which are rusting outsie my back door looking untidy, they won't pick up.
I have emailed and spoken to managers at IKEA it is a waste of time and all it does is gives you stress.
They know what the problems are, they just need to organise a date to come back that is convenient and all will be finished, somehow they don't want to do this adn I am not going to waste any more of my time chasing them with emails and phone calls to sort it out.
