No worries, I didn't realise that they came in other formats.

Mine, and others I've had, has a central lower half pole with bits/holes for putting the branch clumps in, so there's 4 layers of branches each with their 8 branch clumps which you fluff up, so each layer has spokes of branches so to speak. But you can put as many or as few in as you want, and they don't have to be on their specified layer. I make the bottom of mine oval to fit the gap by just switching this round a bit. The top half is just one big bit that I fluff up.

But it's just a cheap 6 foot (they lie it's nearer 5 foot) Sainsbury's tree.

Hope that's made some kind of sense.

Just don't put some of the branches in on a normal fake tree, so it's 3/4 at the bottom, and once you're half way up, it won't matter that it's a full round again.

Yup, I make mine oval at the bottom to fit the gap it needs to fit in, then can round out once it's past the sofa arm.
