Re: Balloon Effect and Perforated Leather
Leather does ballon the cushion if there is no “membrane” for the air to escape from. Fabric cushions don’t suffer as much from the ballooning as air can freely pass through most fabrics.
Tricks to removing ballooning in leather cushion.
- Fabric panles, say 1/3 of the lower back cushion or seat cushion in hidden locations.
- Perforation of leather
For your B&B italia sofa there really isn’t a place to hide fabric panels, or even hide perforations… as such the perforations where turned into a surface texture to allow the cushions to breath (smart in my opinion)
Creating these perforations would typically be cut with a CNC drill punch (down to 1/4") or laser (any smaller) fabric cutter. What I would do in your case is have the upholster cut your pattern pieces and then take them to a laser cutting shop to get the holes created.
