When we built the Traction Model we had to decide on legs. Most L/O`s are high and parents have to lift the kids up. So we attached the folding legs and made the model table hight. Much the the appreciation of many tired family who can let the kids roam around the model. We also put perplex screen allaround for safty. The legs fold neatly within a 30" +4' table, but may protrude with only 24". Just a thought Andrew.
