This was the most difficult thing to put together--and we have done IKEA products.  The fireplace would not open so had to call for tech help.  Still waiting for a call back.  Meanwhile we were able to open the front of the heater after one and a half hours of trying.  The product size and color looks great--but I never would have ordered it if it had any information about the amount of hours (with 2 competent people) that it takes to put together.  Love the finished product, though.
