Just like his great-grandfather, Daniel Heer sources the horsehair for his mattresses from the Toggenburger horsehair spinnery, in the Swiss town of Marthalen. The hair is delivered to Berlin in tightly tressed braids and unwound using a classic model of the “Universalzupfmachine El-Ba Standard” pulling machine. The resulting curls conform to the sleeper’s spine, fostering restorative sleep. Layer by layer Daniel Heer sculpts the horsehair, and ultimately blankets each side with a cover of untreated pure sheep’s wool. This certified “Laines de France“ is sourced from sheep who graze year-round under the open skies of Provence. Their wool is known for its elastic volume-expansion and, just like horsehair, contains outstanding antiallergenic characteristics. It is permeable to air while regulating moisture and temperature.

 

The resulting filling is enfolded in fabric and sewn together with a saddler’s stitch. All edges are then sewn into a typical roll-form for mattress handling; front and back are identical. Finally, tufts bound by the fabric’s weft thread are used to hold the two sides of the mattress to one another, and the horsehair within. Nothing can shift or be displaced for 100 years—the lifespan of such a mattress. After 20 years Daniel Heer will refurbish the mattress upon request, by opening it and allowing the horsehair to loosen and air out in the sun. The mattress is then as comfortable and beautiful as ever.
