The Beddows bought their Adirondack chairs unfinished and had them painted to match the roof. Similar ones are available from L.L. Bean (chair $169, footrest $79).
For the table, the couple fitted a 19-inch-high glazed container (similar from $50) with a 20-inch-diameter tempered-glass top ($30; pier1.com). Small silicone pads cushion the glass.
