Ivar v Hejne

I've moved house 6 or so times in the past two years. When I was moving first, I needed to buy shelving. I knew that it was likely I'd be moving again so the shelves I bought had to be capable of moving with me! And boy, was I right about moving again...!
I dismissed the idea of buying Ikea Billy shelving - bookshelf units that seemed permanent once built. And bulky to move.
So I narrowed the choice down to Ikea Ivar or Ikea Hejne.

Hejne was sooo much cheaper. And they won me over. I bought three Hejne units and 1 Ivar (for testing purposes!). And what am I left with? 0 Hejne + many more Ivars that I've bought over the years.
I didn't like Hejne at all. They were flimsy and cheap. No choice in height. Supposed to be adjustable but really the adjustable heights were so wide apart that the options were limited. I think there was a deep/narrow shelf depth option. I used them both in my utility room and in my sitting room. They didn't look well in the sitting room, the books were never the right scale on the shelves. The utility room was a bit scary cos the shelves didn't feel sturdy enough for all the paint and tools piled on, but then I didn't attach the shelves to a wall which would have provided sturdiness. I thought it would be handy to have four stand-alone posts at the corners that could be used on narrow or deep shelf depths but I think the stand-alone posts caused some of the wobbliness and lack in firmness.

Whereas, Ivar, I love. Very easy to deconstruct and reconstruct. Easy to move (well, with a big car for the super-tall side posts!).
In order to change the shelf heights of Hejne, the unit had to be moved away from the wall to access the allen key screws at the back (and an allen key had to be located) whereas with Ivar, the pins can be pulled out of the holes and the shelf heights adjusted without moving the shelving unit.
Dunno if I'll have them forever and ever, if they'll last *that* long. But they've lastest the 6 moves so far and there's more moves on the horizon.
