@Sandyriver Glad I was of help with the frames. Mine are all hinged doors I'm afraid so I can't help with the sliding doors. If your Ikea is as close as mine is (a mere few miles away) the staff are always really helpful. Or ring them.
But yes, straining not good so wise to leave it.
@MissCherryCakeyBun when you lay the sides down to start the whole process, once you have put in the wall fixing L plates and the cam screw things, if you have any drawers or shelves put the fittings in now rather than squeezing inside the damn thing when it is upright.
Always remember to think about where the door hinges go, this prevents you using certain fittings at the very top or bottom. Some things have fittings underneath and some at the top ie the wooden drawer runner is underneath and the wire basket is at the top.
Ikea tend to have amazing photos of their filled wardrobes but they are open, no doors, so they don't have to consider the hinges.
If you don't know where the door hinges are going to go, before you put any of it together, lie the side piece down, lie the door next to it and line up the top edges, not the bottom as it has that little panel piece (which is why the bottom cam screws are 3 holes up and the top ones are at the edge) then you can see where the hinges will go and won't use those holes.
I actually love putting Pax together.
