The BK13 Cushion is from Carl Hansen and is intended for use with the BK13 hammock. The cushion is weather-resistant and made of canvas fabric, which can be chosen in two colors. BK13 is an outdoor hammock designed by Bodil Kjær in 1959 for the Danish Carl Hansen & Søn. The hammock is made of untreated teak. Over the years, BK13 will develop a very beautiful patina due to being made of solid wood. The hammock belongs to the original collection designed in 1959 by Bodil Kjær. The collection also includes a sun lounger, table, sofa, and chairs.
