AERIS: the 3D printed saddle that embraces your anatomy without foam

Published on May 15, 2026 | Translated from Spanish

Mahdi Naïm Studio presents AERIS, a bicycle saddle that merges additive manufacturing and French textile craftsmanship from its conception. Its lattice structure printed in elastomeric resin via SLA/DLP is not an ornament: it is the functional skeleton that supports the cyclist's weight. The cover of full-grain vegetable-tanned leather, hand-stitched, completes a design that does away with foams and padding.

Three zones, one purpose: biomimetic optimization printed 🚴

AERIS's lattice varies its density according to a biomechanical logic. The ischial zone features high density to provide firm support when seated. A transition zone with progressive density adapts to postural changes during pedaling. The perineal zone, open, relieves pressure on sensitive areas. The entire design is governed by principles of design for additive manufacturing and biomimetic optimization, discarding any filler material. Craftsmanship envelops the technology.

Your backside deserves a lattice, not a sponge 🪑

AERIS comes to remind us that traditional saddles, with their foam and gel, are like a feather mattress: comfortable until you sink in. There are no half measures here: either you bear the resin lattice or you surrender to artisanal leather. That said, if your backside expects the plush experience of a sofa, better look elsewhere. This saddle is for cyclists who want to feel the road, not float above it.
