A slight reinvention of a classic, that being the Lillagunga oak swing by Anton Stenfors.
This is a handmade swing out of Finland, described as safe and durable and good for both indoor and outdoor use. It uses a patented mechanism for attaching the ropes and adjusting the height of the seat, which keeps everything nice and simple and the oak seat is oil treated, presumably for longer life.
The rope is offered in seven different shades, with the bottom line price the same no matter which one you choose. That being €149.
