What a clever idea, a pullout dining area when you need it, built right into the kitchen cabinetry and pulling out like drawers. I don't know how they get such a big table into the counter, perhaps there is a fold in it. Leslie Claggett of KBCulture, a very good British kitchen site, writes a cautionary note:
Without casting any aspersions on either the manufacturers involved or on homeowners of a critical mass, I can't stress enough the importance of checking and rechecking the load limits on both hardware and materials for such an installation.
Can't find any more information at Alno, but love the idea.
