They would work inside or out and are great as seating beside a table as you can always squeeze an extra person on with a bench.
They also make a useful seat in a hallway; line shoes and wellies underneath and they are somewhere to sit while you pull your boots on. Or use them as a contemporary-feel table against a wall; accessorise with a propped picture, a jar of flowers and a few books.
They come in two sizes: 6ft long and 4ft long, but can be made to a specific length if required.
Made to order, so delivery 7-10 days. 

6ft - length 183cm, height 50cm, depth 22cm
4ft - length 122cm, height 50cm, depth 22cm
