Bloom Dining Table - Natural Ash
The Bloom Dining Table in Natural Ash is 125cm across and 76cm high, round on a central base. With nothing at the perimeter, chairs go anywhere around the edge instead of into fixed gaps. It seats four without anyone straddling a leg.
A round table changes how a meal works. Nobody is at the head, everyone can hear everyone, and the extra chair can always be squeezed in. At 125cm across this one seats four comfortably, and crowding it is possible rather than pleasant.
Measure the diagonal of the room rather than the wall. Allow roughly 75cm clear all round for chairs to pull out, which puts the real requirement nearer 2.75 metres in each direction.
The caveat is the height. This one is 76cm, and the range is not consistent across the two sizes, so if you are matching existing chairs measure the gap under the top rather than trusting the nominal figure.
