Annieeg I think the nearest of the Brabantia boards on the Amazon page would be the Titan Oval - it only has these two curved legs, and is especially made so that you can sit down. Sadly though mine does not have the 'well' for putting the steam generator tank in - for some reason back in 2003 this 'well' only came on a cheaper board. Anyway I get around this by standing the steam generator tank on an offcut of some 'floating floor' that is placed right beside me and thus protects the carpet. I have also found that I can buy some ironing board felt in John Lewis (where I bought my board in the first place, and also get replacement covers) - by the way with the replacement covers you get more 'suspenders' with them. So I have a generous layer of felt which goes over the foam that covers the mesh, and then the cover.
I have in the past unpicked the binding that goes around one of the old bought covers, and then used this binding when I have made some smaller covers on my sleeve boards - this particular binding - the way it is made, makes for less bulk when pulling the cover up especially on such a small board. As for my sleeve board, my son made me a super one, really heavy and solid and sturdy, and I have a choice of two sizes of board. Again I covered these with some of the ironing board felt and then some sheeting.
Hope this helps, only other thing I can suggest is that if I charge my camera up and take a photo of the underside of the ironing board - but that will have to be later today as I know the camera needs charging up. But I do think the Titan Oval one is a very good match.
You won't regret having such a big board, makes ironing so much easier, and of course this lives in my sewing room but is folded up against the wall area. For sitting, I using a discarded office chair that has no arms on, but it does have wheels and this is just right and easy to move around.
