This thesis was rendered for the client HAGS Aneby AB that is a global leader in playground equipment. The goal of this project was to develop a seesaw that is available for children aged 5-12 years; both with and without disabilities. The project has aimed to develop a seesaw that fits everyone in the target group without looking specially adapted.

Children with disabilities have difficulty using today's seesaws because they consist of only a seat and a handle on each side. It requires that the user has strong arms and legs and can sit up without support. HAGS Aneby AB would like to change this.

To gain knowledge of the target group and on the different types of disabilities information was sought for on the internet including the RBU's and UNICEF's websites. During implementation several concepts was developed and screened off to finally get the final result. Methods such as QFD, feasibility assessment and Go/No-Go-screening have been implemented. The instructions in the safety standard EN 1176 has been closely followed in the development of the seesaw.

The final concept shows a broad seat with handles, seat backs and footrests on each side of a central section that is in the form of a U. On the sides of the seats there is a high lateral support, to lean against, and a low lateral support. Entry and exit will happen on the side where the low lateral support is situated. Rubber buds are placed on the back of the seats and on the outside of the high lateral support, so that an assistant could be able to assist with entry and exit and also to provide extra speed in use. A rubber suspension unit, that makes the seesaw move, restricts the movement to ± 30˚. In order to stimulate the senses, such as vision and hearing, a ballgame was placed in the middle part of the platform.
