I have the Horn Eclipse, seen
here. I think Koala do a similar model. Best money I ever spent. I don't use the lift up table at the back a lot, but when I need it, it's invaluable. I keep a small iron and pad on the area to the right.
They've just taken out a newer model to accommodate larger machines that need a deeper lift, although my Pfaff QE4 fits the insert fine. I negotiated for a blank plastic insert when I purchased mine, so I'm able to use it as a light box by putting a couple of small lights on top of my machine when it's in the 'down' position.
It's also easy to get spares for (my chair 'ran' away with me and I didn't realise I'd caught the lever on the plastic storage bin until I pulled it away - with me on it. Gonna have to get on that diet
). Happy shopping!
