I bought a Horn Quilters Delight a few years ago, as I was struggling to quilt larger size quilts. Extending the back and side flaps helped greatly to support the weight whilst sewing. With smaller projects, using the left side flap (with drawer pulled out) was great to keep all my sewing tools on. When not in use, the whole thing (including the 3 drawer unit) all fitted together neatly into a space 128x52cms. I am quite petite, so never had any problems with leg room or sewing position.
It was very heavy, so couldn’t bring it back to UK from abroad, and had to gift it to a sewing friend
It was expensive, but I thought it was worth it. I would have another one, but my current room doesn’t have enough space
