I find it hard to believe that the bottom pieces are not folding in from the weight

Its really the simple engineering of the cross sections, makes the whole thing really sturdy

i'm a working dj in nyc and i've had 4 or 5 friends' expedits collapse under the weight of their vinyl.

A lot of my friends use Expedits to stack vinyl and none has collapsed nor have bended lot.

I have Bestå-units to stack my vinyl and few friends use Lundia shelving system.

To JP001, your friends have had the expedit on it's side, not the right way up. No wonder they collapsed...

The side piece should be against the floor, not wall.

all furniture, IKEA or otherwise, have weight limits. Ignore them, assemble it incorrectly, and/or stand it any way than intended, and it will collapse...

granted I dont have a large collection of records, but the IKEA Trissa box is what I use. It holds them perfectly.

Also, those little angles that come with the expedit and are supposed to attach it to the wall? Well, there's a reason for that. With no back on the thing, there's essentially no lateral load tolerance. You could lean on the side of thing and the hardware would pull right out of the cheap particle board. Attach it to the wall, and you've just just increased the lateral strength exponentially.
