13cm long and approx 8cm tall. The base is cut from 5mm thick white acrylic legs with a 3mm support that slots into place to hold the two legs up. You then dab a spot of glue or tape on the 5mm legs. The seat and backrest then stick to the legs to form a bench as shown. We used double sided tape which gave it a good strong hold and was super easy to do. Sold as seen with space on the seat for you to add personalisation if you require.
