Kicki Carlsson, CEO and co-founder of Dröm UK, will take a "step back" from the day to day running of the company, with fellow co-founder Barry Smith set to take over with immediate effect.
Carlsson and Smith co-founded the specialist thermal wellbeing firm in 2002.
Smith will become CEO and will be responsible for project management and sales growth.
Carlsson will become an ambassador for Dröm, continuing to raise the public profile of the company, both in the UK market and abroad, as well as taking an active role as advisor to the management team.
To complete the reshuffle and to support Smith, Erin Lee has been promoted to managing director.
"My decision to step down as CEO took a long time to make and wasn't easy," Carlsson said.
"I love this business and I have seen it grow steadily since the start 16 years ago, with the help of a fantastic team and a lot of hard work.
"I now feel very comfortable handing over the reins to the new management team as they have a wealth of knowledge and a real passion for the company."
