In 1907, Benedikt Heer crafted his first horsehair mattress in Switzerland and established the Heer Saddlery.
In 2007, Daniel Heer brought this traditional craft to Berlin, continuing it into the fourth generation.
In 2015, he introduced the "Schöneberger Zimmer Concept," offering a guest room experience within his Berlin-Schöneberg workshop, where visitors could try out the horsehair mattresses for a night.
In 2022, he initiated the collaborative project "Sleep We Make," bringing together various workshops and designers with the shared goal of exchanging ideas, merging their individual expertise, and collectively designing a collection - everything for a good night's sleep.
