Ever needed that little private space just for an hour, for half a day or even for a week? Or ever needed a meeting room without having to pay a fortune for an hour? If you or your friends had tree houses when you were kids you probably remember the feeling of being able to sneak out from home and spend some time in the tree house. Peace and quiet, safe… and almost a bit magical. Well, you can now enjoy these same feelings at work! With different sized “koja’s” for every need. “Koja” is the Swedish word for tree house, but we decided to spell it Coya instead – so now everyone can pronounce it! Coya is the perfect solution for: - Video meetings when all private rooms at the office are booked. - Calls or work “on the go”, between meetings - Working from home when your partner or kids are too noisy - Meetings with the whole team (up to six persons) - That quick, or long, meeting with a client or co-worker - A full working day with great ergonomics All Coya’s are equipped with free wifi, an external monitor (not in Mini Meet), ergonomic seating, sound insulation and ventilation that changes all air every 60 seconds. You can find and book your Coya in advance or on the go. You unlock it with the tap of your phone and you will be good to go directly! New locations are added constantly so be sure to download the app and explore new spots to spend your nomad or hybrid work day from!
