Knoll sofas usually lean architectural—clean lines, expensive materials, and silhouettes that still look current decades later. In this sofa review, we compare four core models using the same rubric—seating geometry, support, breathability, cleaning effort, layout fit, durability signals, and value—so it is easier to match the right sofa to the way you actually sit.

Which Knoll Sofas Are We Comparing?
| Sofa | Overall Score | Pros | Cons | Ideal For | Current Listed Price |
|---|---|---|---|---|---|
| Florence Knoll Sofa | 4.1 | Upright sit, iconic profile, excellent build | Not built for deep lounging; expensive | Design-led rooms, conversation, TV | $18,297.00 |
| Florence Knoll Relaxed Sofa | 4.2 | Deeper seat, softer lounge feel | Depth can crowd smaller rooms | Movie nights, relaxed lounging | $15,101.00 |
| D'Urso Sofa | 3.9 | Deep, low lounge feel | Low seat height; needs space | Sprawling in larger rooms | $16,985.00 |
| Pfister Sofa | 4.0 | Balanced footprint, lower visual mass | Low profile will not suit everyone | Full-size seating in tighter layouts | $7,774.00 |
Testing Team Takeaways
In our hands-on testing, most of the separation came down to seat proportions. Seat height affects how easy a sofa is to get in and out of, while depth and back angle decide whether you perch, lean back, or fully curl up.
The standard Florence Knoll is the most posture-forward. The Relaxed version keeps the same design language but gives you more room to settle in. D’Urso is the low, roomy choice for bigger rooms, and Pfister is the easiest full-size option to place if you want Knoll style without the biggest footprint.

How We Tested These Sofas
We scored each sofa using the same assembly/setup, cooling and breathability, and comfort framework, then weighted durability signals, layout practicality, cleaning effort, and value. Our testing started with published dimensions and construction details, then translated those specs into real-world questions: how the sofa supports different postures, how much floor space it takes, and how much upkeep it is likely to ask for over time.
Knoll: Our Testing Experience
Florence Knoll Sofa
Our Testing Experience
In our testing, the standard Florence Knoll made its priorities clear right away. The 17.5-inch seat height and relatively trim 32.25-inch depth keep you stacked rather than sprawled, so it feels better for conversation, TV, or a laptop session than for all-day lounging.
When Marcus and Carlos tried it, both landed in the same place: it feels composed and supportive, but it does not invite you to disappear into it. If you like a structured perch—or want a room to stay visually open—this is the most disciplined model in the group.
What we liked
-
Supportive, tailored sit that stays upright
-
Smaller footprint than the deeper lounge options
-
Strong material and frame package
Who it is best for
-
Upright sitters for TV, conversation, or laptop use
-
Design-led rooms that need a restrained silhouette
-
Buyers who want the classic Florence profile

Not the one to buy for deep lounging
-
Price is still the biggest barrier
Pros & Cons
| Pros | Cons |
|---|---|
| Tailored posture | Not a deep lounge seat |

Florence Knoll Relaxed Sofa
Our Testing Experience
The Relaxed version keeps the Florence silhouette but softens the sit. At 35 inches deep, it immediately feels more forgiving: you can lean back, pull your feet up, and stay there longer without fighting the sofa.
In our testing, Mia and Jenna kept coming back to the same trade-off. The extra depth is great for movie nights, but shorter users may want a lumbar pillow to avoid sliding forward. In tighter rooms, that added depth also changes the traffic flow fast.
What we liked
-
Deeper seat for longer lounging
-
Same Florence look with a softer feel
-
Premium build stays intact
Who it is best for
-
Loungers, nappers, and long TV sessions
-
Couples sharing the sofa for extended sitting
-
Rooms that can absorb a 35-inch depth
Where it falls short
-
Can feel too deep for petite users
-
Tufting and upholstery still take maintenance
Pros & Cons
| Pros | Cons |
|---|---|
| Deeper lounge geometry | Can feel too deep for shorter legs |
| Softer sit without losing the Florence profile | Larger footprint than the standard version |
| Premium construction | Upholstery maintenance still varies |

D'Urso Sofa
Our Testing Experience
D’Urso is the clear sprawl-first option. The 40.5-inch depth and 15.5-inch seat height give it a low, settled feel, so you naturally end up sitting sideways, pulling your legs up, or treating it more like a landing zone than a formal perch.
In our hands-on testing, Jamal and Marcus both liked the sink-in comfort, but they also flagged the practical downside: the low seat turns frequent stand-ups into work, and the footprint needs real front-to-back clearance.
What we liked
-
Low, lounge-first posture
-
Deep footprint for curling up
-
Best fit for open rooms
Who it is best for
-
Anyone who sprawls or naps on the sofa
-
Taller users who dislike shallow seating
-
Large rooms that can absorb the depth
Where it falls short
-
Low seat height makes stand-ups harder
-
Bulky footprint limits layout flexibility
Pros & Cons
| Pros | Cons |
|---|---|
| Extra-deep lounge feel | Needs real floor depth |
| Comfortable foam-and-fiber build | Low seat height may annoy some users |
| Great for sprawling | Not ideal for upright work |

Pfister Sofa
Our Testing Experience
Pfister feels like the easiest everyday compromise in the lineup. At 33 inches deep and 26 inches high, it stays low-profile and unmistakably Knoll, but it does not swallow the room the way D’Urso can.
Carlos and Jenna both found it easier to live with from one posture to the next. You can sit upright, then relax back without the sofa forcing either extreme. The trade-off is the usual low-profile one: if you prefer a higher, more chair-like perch, it may still feel a little low.
What we liked
-
Full-size sofa with manageable depth
-
Flexible posture for mixed use
-
Best value in this group
Who it is best for
-
Buyers who want a full sofa in tighter rooms
-
People who switch between upright sitting and relaxing
-
Anyone who wants Knoll style without the highest buy-in
Where it falls short
-
Low profile will not suit everyone for frequent stand-ups
-
Less dramatic lounge feel than D’Urso or the Relaxed Florence
Pros & Cons
| Pros | Cons |
|---|---|
| Space-efficient full-sofa proportions | Low profile can feel too loungey |
| Flexible sit | Less dramatic than the deepest picks |
| Better value than its peers | Upholstery still drives upkeep |

How Do the Scores Compare?
| Sofa | Overall Score | Seat Comfort | Back Support | Seat Depth Fit | Cooling / Breathability | Durability | Layout Practicality |
|---|---|---|---|---|---|---|---|
| Florence Knoll Sofa | 4.1 | 4.1 | 4.2 | 4.0 | 3.7 | 4.6 | 4.1 |
| Florence Knoll Relaxed Sofa | 4.2 | 4.4 | 4.1 | 3.8 | 3.6 | 4.5 | 3.7 |
| D'Urso Sofa | 3.9 | 4.4 | 3.8 | 4.2 | 3.5 | 4.2 | 3.2 |
| Pfister Sofa | 4.0 | 4.0 | 4.0 | 3.7 | 3.6 | 4.1 | 4.3 |
The same pattern held in our scoring. The Relaxed version wins on comfort if you have the room for it, the standard Florence stays the best upright option, D’Urso is the most lounge-biased, and Pfister is the balanced option—the easiest full-size sofa here to place and live with day to day.
How to Choose Between These Knoll Sofas
Start with how you sit, then confirm your room depth. If you spend most of your time upright—conversation, TV, or occasional laptop use—the standard Florence is the most structured choice. If you need the smallest footprint overall, the two-seat Florence Knoll is also the most compact piece here.
If you want the same visual language with a softer, deeper sit, the Relaxed version is the better match if your room can spare the extra depth. If you want the biggest lounge feel, D’Urso is the clear sprawl-first pick. If you want a more manageable depth in a full-size sofa, Pfister is easier to place. For petite users, deeper seats usually work better with a lumbar pillow so your feet can stay planted and your back stays supported.
Limitations
These are premium, design-led sofas, and the trade-offs stay real: high prices, upkeep that changes with upholstery choice, and dimensions that can feel unforgiving when they do not match your body or room. The deeper models eat floor space quickly, and the lowest seats are not ideal if you are getting up often. If you want a low-fuss family couch first and a design icon second, this lineup may feel demanding.
Knoll Sofas vs. Alternatives
-
Why you’d pick these models
-
You want modern classics with long-lived proportions and strong brand provenance
-
You care about frame and cushion construction that is designed for longevity
-
You want more upholstery and finish choice than a fixed-configuration sofa gives you
-
-
Alternatives worth considering
-
Herman Miller: similar MillerKnoll design language with strong materials
-
Room & Board: better value and easier everyday upholstery
-
West Elm: more accessible pricing with broader performance-fabric availability
-
Practical Tips Before You Buy
-
Measure front-to-back clearance before anything else; deep sofas erase walkways fast.
-
If you go deep, plan on a lumbar pillow to keep your lower back supported.
-
If you run warm, choose breathable weaves over plush, dense surfaces.
-
Light upholstery looks sharp, but it benefits from throws, covers, and stricter snack rules.
-
Low seats can feel great for lounging; just make sure getting up still feels easy.
-
If pets share the room, avoid loose weaves that catch claws.
-
Rotate removable cushions to spread wear more evenly.
-
Match the posture to your habits—TV and work usually reward a more upright sit.
-
Keep cleaning tools nearby so spills get handled quickly.
FAQs
Which Knoll sofa is best for lounging and napping?
For full sprawl lounging, the D’Urso Sofa is the best fit. If you want a softer sit without committing to D’Urso’s footprint, the Florence Knoll Relaxed Sofa is the better middle ground.
Which option works best in a smaller living room?
If you need the smallest overall footprint, the two-seat Florence Knoll is the easiest fit. If you want a full-size sofa that still stays relatively manageable front to back, Pfister is the safer choice.
Are these sofas good for upright back support during long TV sessions?
The standard Florence Knoll Sofa is the most upright and posture-controlled option, so it works best for longer TV sessions when you want to avoid slouching.
Which one is easiest to keep looking clean?
Upholstery choice matters more than model, but simpler surfaces are easier than tufted ones. If low upkeep is the priority, darker, tighter weaves are the safest route.
