Pottery Barn’s PB Comfort Modern Square Arm Sofa pairs a clean, modern profile with a higher, supportive seat and an unusually broad range of configurations. After two weeks with the 62-inch memory-foam version, its best use became clear: this is a strong everyday sofa for people who move between upright work, conversation, and relaxed TV time. Its 39-inch footprint and rising price make less sense in a tight room or for anyone who wants a low, feather-soft lounge seat.

PB Comfort at a Glance

|---|---|---|---|---|
| PB Comfort Modern | 4.0/5 | Seven widths; multiple cushion layouts and fills; supportive seat | Large footprint; upgrades get expensive | Work, conversation, and TV in one room |
Should You Buy It?
The PB Comfort Modern Square Arm is worth considering when you want one sofa to handle both upright and relaxed use. Its 20-inch seat height made standing up noticeably easier than it is on lower lounge sofas, while the 22-inch inside seat depth left enough room to recline without pulling us into a slouch. The memory-foam configuration held its shape well and felt supportive rather than hard.
The biggest compromise is space. The sofa is 39 inches deep overall even though the usable seat depth is more moderate, so the frame takes up more floor area than its sitting position suggests. Fabric, width, and cushion upgrades also change the final price quickly. In a small space, or if your priority is a low, cloud-soft seat, there are better matches.

How We Evaluated It
The 62-inch memory-foam version spent two weeks in a normal living-room rotation. For setup, we recorded its condition on delivery, placement effort, and the time until it was ready to use. Cooling checks tracked surface warmth during hour-long sits. We judged comfort through upright work, conversation, and side lounging, then used repeated edge sits and cushion-recovery checks to assess early durability. We also recorded stain cleanup, cushion maintenance, and how the 39-inch frame affected daily traffic flow using our layout-practicality method. The final value score reflects the tested configuration rather than the lowest advertised price.
Our Testing Experience
The sofa felt more upright than its broad frame suggests. Our tape measurements matched the listed 62-inch width and 39-inch overall depth, while the usable seating area measured 48 inches across and 22 inches deep. That combination gave one person plenty of room to work in the center and still left enough space for two adults to sit without pressing into the arms.
The poly-wrapped memory-foam cushion kept us level during laptop sessions instead of tilting the hips backward. With no one seated, the front edge measured 20 inches from the floor; under a 180-pound tester, it settled to about 18.6 inches. After 50 repeated edge sits, the cushion recovered to within one-eighth inch of its starting height in roughly a minute, and the front seam stayed straight. Those results support the firm-but-comfortable feel we noticed in daily use.
During a 60-minute session, the surface of the tested performance weave warmed by about 5°F. It never became clammy, but it held more heat than a loose linen weave. The square arm stayed steady under an elbow or small tray, though its firm edge needed a pillow for side lounging. Compared with lower, softer sofas, the PB Comfort was easier to stand up from and better for posture changes; it was less inviting when we wanted to sink in and stay put.

Choosing the Right Configuration
Start with the footprint, not the width alone. Tape a 39-inch-deep rectangle on the floor, then leave room for the main walkway and enough reach to the coffee table. The 62- and 71-inch versions solve a width problem, but their full depth can still crowd a small living room.
Next, choose the sit. Memory foam is the stronger option for upright work, frequent posture changes, and consistent support. Down blend feels softer at first contact and suits relaxed lounging, but it needs more regular fluffing. The 20-inch seat height works especially well for medium-to-taller adults. Shorter users may want a lumbar pillow so they can sit back without losing contact with the floor.
Finally, order swatches and read the care code for the exact fabric. A performance label does not make every weave feel or clean the same. Confirm delivery access, diagonal depth, lead time, and return eligibility for the finished configuration before placing the order.

What to Know Before Buying
This is a supportive everyday sofa, not a low, loose-cushioned lounger. The memory-foam version allowed comfortable posture changes, but it never produced the deep sink some people want for long sprawls. Its 39-inch overall depth also matters in tight rooms, even though the inside seat depth is a moderate 22 inches.
Cost and return flexibility require equal attention. Wider sizes and premium upholstery can move the price well beyond the entry configuration. Made-to-order and custom upholstery is generally non-returnable, while eligible Quick Ship upholstery has a shorter return window. Treat the swatch, floor template, and final order summary as part of the buying decision.
How It Compares With Similar Sofas
Room & Board Metro Sofa: The Metro sits lower and feels softer, with blend-down seat cushions and a relaxed back. Choose it if you want a more enveloping sit and do not mind a 17-inch seat height. The PB Comfort is the better fit for easier standing, a higher posture, and a choice between cushion fills.
Crate & Barrel Gather Sofa: The standard Gather uses innerspring seat cushions wrapped in foam and fiber, creating a plusher first impression. It is a good alternative when lounging matters more than upright laptop use. The PB Comfort offers more fill choice and stronger support at the front edge.
West Elm Harmony Sofa: West Elm rates the standard Harmony at 1/5 for firmness, making it the softest option in this group. Its low-pressure feel suits curling up and long movie nights. The PB Comfort feels more controlled and is easier to move in and out of. The standard Harmony is not modular; West Elm sells a separate Harmony Modular line.

Tips Before You Order
-
Mark the full 39-inch depth and the main walkway with painter’s tape before choosing a width.
-
Measure the delivery path as well as the room, including doorways, turns, stairs, and elevator openings.
-
Choose memory foam for steadier support or down blend for a softer sit.
-
Order upholstery swatches and check them in daylight, lamplight, and against bare skin.
-
Read the exact fabric care code; cleaning rules differ across the upholstery library.
-
Rotate loose seat cushions and reset the back cushions weekly to distribute wear.
-
Vacuum seams and the deck under the cushions before grit can work into the fabric.
-
Confirm whether the final configuration is Quick Ship, made to order, or custom before relying on a return window.
-
Use a coaster or tray on the square arm to prevent moisture and pressure marks.
FAQs
Does the 39-inch depth feel too deep?
The frame is deep, but the usable seat is not extreme. The 62-inch version has a 22-inch inside seat depth, which supported both upright and semi-reclined positions. The bigger concern is floor space: the full 39-inch frame can narrow a walkway or push a coffee table too far into the room.
Is memory foam or down blend better for daily use?
Memory foam is the better match for upright work and consistent support. It recovered quickly after repeated sits and required little reshaping. Down blend gives a softer first contact and a more relaxed look, but it needs more fluffing.
How supportive is the front edge?
The memory-foam cushion stayed stable during quick stand-ups. Under a 180-pound tester, the front edge compressed by about 1.4 inches, then recovered to within one-eighth inch of its starting height in roughly a minute after repeated edge sits.
How do you keep the cushions wearing evenly?
Rotate the loose seat cushions when the layout allows, vary your usual sitting spot, and reset the back cushions once a week. Vacuuming the seams and cushion deck also keeps grit from wearing one area faster than the rest.
