Hippo is a real eye-catcher and the perfect frame made of untreated spruce wood for the Kaya natura and Kangoo baby hammocks (hammock not included). Hippo is very stable and features a swing limiter. The exclusive design makes Hippo a true gem in the home or garden. It can be easily and lightly carried, allowing you to keep your baby close at all times. When treated with non-toxic stains, Hippo withstands any weather.
