About the team

One weekend, one Impacthon and three consultants passionate about sustainability. That’s how Sleepify was born.

At Sleepify, we believe everyone should have access to a good night’s sleep. We are a B2B circular mattress provider who specialise in producing luxury mattresses, at an affordable price. Through our circular and sustainable approach we have a positive impact on our customers and the planet.


The Impacthon was an action packed 3-day event that enabled us to tackle a sustainable challenge head on in partnership with Greiner. The coaching and resources provided by circle17 have been extremely helpful in supporting Sleepify to take our idea and turn it into an initial start-up. We are excited to continue our journey, working with Greiner to validate our idea!

Specify the problem you are trying to solve: 

In Europe alone, 18 million mattresses go to landfill every year (European Commission). At Sleepify, our mission is to end mattress waste. We want to create a circular model for mattresses to be produced, consumed and then recycled or reused.

Describe your proposed solution:

Overall, our solution aims to create a mattress which is fully recyclable and sustainable. We also aim to provide our customers with high quality mattresses and offer them flexible payment solutions such as a monthly subscription or ‘pay per use’ model. As part of our service, we integrate a ‘take back’ scheme at the end of the mattress life cycle, ensuring mattresses are repurposed or recycled. The end result is a mattress production and consumption process that is fully circular.
