The Stacked Cushion Patent That Redefined Comfort Engineering
Imagine cushions designed to stack perfectly on top of each other without squishing flat or sliding around. This patent covers the specific way cushions and their internal layers can be built and stacked to stay comfortable and stable, even when you pile them up or use them together.
The plain-English version
What it protects
The claim covers stacked cushion configurations and the cushioning elements that make up their internal structure, along with the specific materials and manufacturing processes used to create them. What's protected here is the engineering behind how multiple cushions can be layered, stacked, or combined while maintaining their individual cushioning properties and structural integrity.
Why it matters
Cushioning is fundamental to furniture design, and improving how cushions stack and perform when layered addresses a real practical problem: creating durable, comfortable seating and bedding that doesn't flatten or degrade over time. Better stacking geometry and material engineering can reduce manufacturing costs, extend product lifespan, and improve comfort — all valuable in the competitive furniture market.
Real-world use
Every time you sink into a couch with multiple cushion layers or adjust stacked seat cushions on a dining chair, you're experiencing cushioning engineering covered by patents like this one.
Original USPTO abstract
Stacked cushions, cushioning elements thereof, materials and processes for making the same are disclosed.
