Virgin Galactic had a 'virtual reveal' of the interior design of Spaceplane Two, the passenger cabin designed to safely carry tourists over 50 miles above the Earth for rocket powered suborbital hops. It's not as simple as picking out nice colours and fancy materials, the seats need to secure the passengers through acceleration and aerobraking, which have different orientations. They also need to provide enough room for passengers to make full use of the cabin during zero g, enough windows to observe the earth from far above, and make it easy to get back in when the deceleration starts.
