Shencot House in Rustington is now home to a Red Arrows themed childrens bedroom.
It features Airfix Red Arrows Hawks in flying formation, Airfix coasters, books and Corgi die-cast Red Arrows.
Airfix also supplied the beds, bedding, curtains and furniture as well as a Scalextric set and a Hornby trains set.
Shencot House is used exclusively by serving RAF families who are in need of an affordable getaway.
"We are delighted to be able to provide products and equipment for such an important project," said Darrell Burge, marketing manager for Airfix.
"It is essential that RAF families feel that Shencot House is a second home and we hope that our Airfix models and other Hornby toys will go some way to help achieve that goal."
Shirley Steeples, general manager of the house said: "I would like to thank all the people who have contributed so much to help us complete Shencot House in good time, both financially and practically. Among those who have shown their support are the RAF Charitable Trust, members of the local community, local businesses, corporate supporters like Airfix and Howden’s Joinery, and serving RAF personnel.
"We enjoy wonderful support from all those who appreciate the magnificent work the RAF does in defence of our freedom, and we continue to be surprised and delighted by their generosity. Shencot House will make a big difference to hard pressed RAF families, and also help cement the special relationship the Littlehampton area has developed with the RAF."
