I've got loads of the stuff in the kids bedrooms.

You should have got a number of metel pegs with the shelving. If you
haven't
got these, then Ikea can supply them separately.

These go into the holes in the side pieces. If you look under the shelves,
there is a metal "slot" in each corner, which fits over the metal pegs. In
its simplest form, you have two side panels with the pegs pointing
inwards -
4 for each shelf, all at the same height. This can be expanded as far as
you
like, with more side panels and shelves (you only need to add 1 side panel
for another "column" of shelves - ie 2 shelf width = 3 side panels, 4
shelf
width = 5 panels and so on.

I've screwed the side panels to the wall with one screw at the top of each
side panel. Once the shelves are in place, this arrangement is rock solid.
I've also cut out at the bottom rear for the skirting board.

Note that Tony has screwed the side thingies (like a ladder) to the wall.
If you just put up IVAR shelving, with the cross brace (metal folding cross)
screwed to the back to provide some rigidity, there is still quite a bit of
wobble, and getting everything vertical can be a problem.
The strategy of resting the shelf ends on pegs does not provide a rigid
structure!
Not an issue for bookshelves etc, but not so good for built in cupboards.
I tend to add additional bracing of some sort.
For tall shelving, there is also a strap which should be screwed to the top
of the 'ladder' and to the wall as an 'anti-topple' device.
