The Elements of Upholstered Furniture

The Elements of
Upholstered Furniture

Whether it's a sofa, chair, sectional, or chaise, there's nothing quite like the comfort of beautifully upholstered furniture. But what goes into crafting upholstered furniture, and what sets truly high-quality pieces apart?

The diagram above shows the common elements of any upholstered piece. Most are self-explanatory, but we'll walk you through a few of these terms. The frame is often made of wood and forms the interior shape of the furniture. Think of the frame as the skeleton; it's what provides strength and structure for all that goes on top of it. The decking is the platform that supports the seat cushion, providing comfort and durability. The apron is the layer of separation between the base and the seat cushion. The arm gives upholstered furniture shape and personality.

What's Inside

What's Inside

The construction methods, pitch (the angle of the seat back in relation to the seat), and fill materials determine the level of durability and comfort of any given seat. The interior of any upholstered furniture will often feature a wood frame, at least one layer of padding (typically polyester fiber, polyurethane foam, and/or batting), and a suspension system. We'll dive into this more below.

Strong Frames,
Made for Real Life

The way a frame is made determines how a piece holds up under real life (years of sitting, shifting, and the occasional kid jumping on the cushions). Our frames are built with exceptional care to provide support for decades.

Premium Materials: Kiln-dried hardwoods and engineered hardwoods

Sustainability: Most of the hardwoods we use are FSC® Certified, formaldehyde-free, and sourced from U.S. forests

Durable Joinery: Mortise-and-tenon joints, double-dowel joints, and corner blocks hold everything in place

Furniture That
Holds You

The suspension system is a layer of support
beneath the cushions that supports the weight
placed on the seat.

8-Way Hand-Tied

How it works: Individual coil springs are hand-knotted with twine at eight points on each spring and attached across the seat's frame.

Why you'll love it: Considered the gold standard in suspension methods, this method is beloved for its high quality and longevity, creating heirloom-quality pieces built to last decades.

Sinuous Springs

How it works: Tight S springs made from heavy-gauge steel are attached at even intervals across the frame.

Why you'll love it: Less labor-intensive (and less costly) than eight-way hand-tied, this method provides consistent comfort and lasting durability.

Webbing

How it works: Polypropylene bands are attached across the frame in a crisscrossed pattern.

Why you'll love it: A more affordable suspension method that still offers plenty of durability (and no squeaking, ever). Perfect for smaller pieces like ottomans or modular sectionals.
