We stand with Ukraine Our thoughts remain with those affected

Together with the rest of the world, we are watching the tragic and unprovoked attacks unfold in Ukraine with sadness and disbelief. Our hearts break to see so many people devastated, and the resulting humanitarian crisis.

We have a number of links to Eastern Europe as a business, and through a joint effort between our wider company (the John Cotton Group) and colleagues we have been supporting the humanitarian crisis through the donation of over 5,000 pillows and duvets, as well as collecting essential goods which have been sent in trucks to those displaced to Poland. In addition to this support, the John Cotton Europe business has so far employed 10 Ukrainian refugees which will enable these individuals to start to rebuild their lives.

At Sleepseeker, we believe in the power of many, and we hope many of you reading this find ways to support the Ukrainian people as our thoughts remain with those affected by this crisis.
