Knowing all of the different parts of sofa and couch models will save you time when buying the best sofa for your living room and help you buy the exact one that will meet your needs.

1. Attached Back

The cushions are attached, clipped, or sewn to the back of the sofa. The good thing is that they usually stay nicely in place, and you don’t have to keep moving them or plumping them up regularly.  

2. Pillow Back

The back design has more cushions than the seating area, making it softer. It provides back support and optimal comfort that you can adjust by moving the cushions around. However, this back design requires more maintenance.

3. Tight Back

The tight-back design is upholstered but doesn’t have loose cushions. As a result, the back is strong and can create a clean, fitted, and formal appearance. Besides, the tight-back design is often accompanied by a tight seat.

4. Channel Back

Like a tight back, a channel back design has deep vertical grooves features.

5. Loose Cushion Back

Unlike attached back sofas, loose cushions are separate seat cushions from the sofa back. This makes cleaning easier. Besides, these are cushions that you can move, similar to cushion seats.

6. Camel Back

As the name implies, this type resembles the shape of a camel’s hump, high in the center and sloping down lower at both ends. It often gives off a formal appearance. Think of the type of sofa on which the royal family may sit for an official portrait.

7. Curved Back

A curved-back sofa’s back bends all the way around, forming one piece with the arms that aren’t attached separately.

8. Waterfall Back

The waterfall back usually features two or more vertical layers of gathered and billowing cushions attached to the back.

1. Rolled Arm

The rolled arm design is a standard shape for sofa arms; a rolled arm curves outward. It’s very comfortable for sitting around with a book or a box set. However, though rolled arms are comfortable for lounging and reading, they take up more space.

2. Lawson Arm

A Lawson’s arm is a low-profile, scaled-down model of a rolled arm.

3. English Roll Arm

An English roll arm is low and set back from the seat’s front edge, as seen on classic country design sofas, such as those in comfortable inns next to a blazing fire. English arm designs are low-profile and ideal for taking naps on your sofa. They are also suitable for small places since they do not protrude beyond the sofa’s body.

4. Tuxedo Arm

This is a slightly flared arm with the same height as the sofa seat back, giving an on-trend contemporary aesthetic.

5. Pleated Arm

A pleated sofa arm is similar to Lawson’s but without the fixed front panel. Instead, the arm design comes with pleated fabric on the ends.Also, the front part extends from the inside of the arm.

6. Square Arm

A square arm (also known as a box arm) usually gives the sofa clean straight lines and angles if you like a minimalist appearance. In addition, square arms are handy in the entertainment space since they serve as seats. However, they aren’t as comfortable as rolled arms.

7. Track Arm

The track arm is a sofa arm design with flat parallel sides and a flat top.

What Are the Main Types of Sofa Seats?

1. Cushioned Seat

A cushioned seat is made up of two or three cushions. The seat cushions (referring to the part of the couch you sit on) are often firmer than back cushions since they are designed to sustain the weight of any sitter. On the other hand, the shape of the cushions depends on how many they are on the seat. Plus, they can be either square or rectangular. Besides, the end cushions are sometimes T-shaped to accommodate the arms.

2. Single-Cushion Seat

Some sofa seats (bench seats) usually come with one cushion. Besides, a bench seat gives a neat, simple appearance that can be combined with a pillow back which is more about casual comfort rather than minimalism.

3. Tight Seat

Tight seats are sofas that don’t have separate seat cushions. This design is common on both traditional and modern sofas, as well as those with wood frames. It usually portrays a formal appearance.

What Are the Different Sofa Parts?

i). Frame

The frame has the bones of a sofa which usually determine its shape and quality. For instance, most high-quality sofas feature kiln-dried hardwood frames with sturdy reinforced joints.

ii). Sofa Bed Frame

Some sofas can fold out to act as a sleeping area. For example, a foldable bed frame often rests beneath the seats or cushions of a sofa bed or futon. The spring-loaded bed structure is normally covered by the sofa’s external frame when using it as a seat.

iii). Deck

This is the surface right beneath the seat cushions.

iv). Plinth Base

A plinth base is a box-like base commonly used on modern sofas in place of traditional legs.

v). Down-Proof Ticking

Down-proof ticking is the tightly woven inner lining of a cushion that usually prevents tiny down feathers from getting out of the cushion.

vi). Filling

Filling may be padding, down, or foam to make the sofa cushion comfortable.

vii). Webbing

Webbing comprises interwoven strips of synthetic material fastened to a sofa’s wood frame. It’s commonly used in place of support springs.

viii). Eight-Way Hand-Tied Springs

Hand-tied springs are connected with sturdy twine that goes side to side, front to back, and diagonally in both directions. The springs are interconnected in this structure for durability and consistent support.
