Have a Rossmore dining table that extends and find it great for a large family dinner. No problems with it jamming when opening or closing but yes you do need to be very carefull with the little fingers. I find the ends can slide together a bit too quick at times so you need to be vigilant !!I'm considering buying an oak dining table that extends from about 180cm to 240cm. Just wondering if anyone has had problems with extendable tables - do they jam, fall apart, can kids catch fingers in them etc. Thanks.
