The Akura Bench is purposed most often as a Hall Bench or Coffee table ergo we make it with a flat wood seat. If you want a bench to place around a dining table see the "Cove Bench". Its' scooped seat is made for serious sitting at a table with a handy to store bench. Height is 18".
A variety of lengths is available in the drop-down options above. If using as a bench first consider the distance between dining table legs, then assume each person will need at least 24" or more. People can be crowded into less than 24" per person if they are not big, and it also helps greatly if they are glad to be at your house and like their neighbor.
Below the "backless" benches on the Bench page you will see our Pacific and Kyoto benches with backs and scooped seats which are made for hours of sitting.
