Why oh why don't Ikea do a 2x3 Kallax 


I thought I'd found a solution hacking a 2x2 and a 3x3 into 2 2x3 units. Only to find they don't do a 3x3 in this country 
Does anyone have this Argos/Hygena Cube Storage
Does it fit Ikea sized innards? I don't want canvas boxes, I want Ikea drawers & doors?
Help!
I'm supposed to be taking DC to Ikea tomorrow, I need to know what I'm getting. Other than a crapton of Daim bars
