Bolia's four best-known sofa families can look surprisingly similar online, but they serve very different ways of sitting. The biggest choice is not color or leg finish. It is whether you want a low, deep lounge sofa or a more supportive seat that is easier to use every day.
Cosima is the deepest and softest of this group. Noora keeps much of that roominess while adding more support. Caisa has the lightest visual footprint, while Scandinavia offers the most familiar proportions for a mixed household. This comparison explains where each one works—and where it does not.

Quick Verdict
| Sofa | Overall Score (/5) | What Stands Out | Best For |
|---|---|---|---|
| Cosima | 4.3 | Very deep seat, soft down-and-feather comfort, flexible modules | Long lounge sessions and larger rooms |
| Noora | 4.2 | Two depths, balanced support, tailored modular shape | Everyday sitting and relaxed lounging |
| Caisa | 4.1 | Raised steel base, compact overall depth, supportive feel | Smaller rooms, reading, and conversation |
| Scandinavia | 4.2 | Familiar proportions, reversible cushions, classic profile | Families and mixed-height households |
Which Bolia Sofa Should You Buy?
Choose Cosima when the sofa's main job is lounging. Its 40 cm seat height, 72 cm seat depth, and 105 cm overall depth create the lowest, most relaxed posture in this comparison. It is comfortable with your legs up, but it asks more of shorter sitters who want to sit upright.
Noora is the better all-rounder. The standard 107 cm-deep modules have a 64 cm seat depth, while the deeper 127 cm modules increase usable seat depth to 84 cm. This clear standard-versus-deep choice makes Noora easier to tailor to a room and a preferred posture than the source article suggested.
Caisa is the strongest fit when floor space and easy movement matter. Its representative three-seat configuration is only 91 cm deep, making it easier to place with other apartment-size sofas, and the 44 cm seat height plus 20 cm legs make standing up feel less demanding than it does on Cosima.
Scandinavia is the safest choice for a household with different body types. Its 45 cm seat height and 58 cm seat depth give it the broad fit expected from the best sofas for families, and the reversible cushions let buyers choose a softer down-and-feather fill or a firmer foam option.
- Seat depth changes posture more than any styling detail.
- Cushion fill determines how much you sink and how often the seat needs reshaping.
- Changeable upholstery is configuration-dependent and does not mean every cover is machine washable.
- Modularity is useful only when the available pieces suit the room and the way you sit.
Key Dimensions and Materials
| Sofa | Style | Representative Size (W × D × H) | Seat Depth | Cover Approach | Cushion Construction | Best Fit |
|---|---|---|---|---|---|---|
| Cosima | Low modular lounge | 246 × 105 × 66 cm | 72 cm; deeper modules available | Changeable upholstery on current configurations | Cold-foam support with down and feather | Deep lounging and large rooms |
| Noora | Tailored modular sofa | 250 × 107 × 80 cm | 64 cm standard; 84 cm deep | Changeable fabric covers; fixed leather upholstery | Foam, duck feather, and polyester fiber | Balanced everyday use |
| Caisa | Raised modular sofa | 242 × 91 × 73 cm | 70 cm | Varies by upholstery and configuration | Supportive upholstered cushions | Smaller layouts and upright use |
| Scandinavia | Classic Danish profile | 236 × 92 × 78 cm | 58 cm | Removable fabric upholstery | Choice of down/feather or foam | Mixed households and daily use |
Bolia: Our Testing Experience
Cosima
Cosima is the clear lounge specialist. Its low back, wide arms, and loose cushioning encourage you to settle in rather than perch at the front of the seat. Among these four sofas, it creates the strongest visual statement and demands the most floor space.
Our Testing Experience

The representative build pairs a 72 cm seat depth with a 40 cm seat height and a 105 cm overall depth. Those numbers matched the way it felt in use: comfortable with both feet up, but too deep for a shorter sitter to use the backrest while keeping both feet flat. A lumbar pillow improved upright support, though it reduced the open, relaxed feel that makes Cosima appealing.
What we liked:
- The soft down-and-feather layer spreads pressure well during long, legs-up sessions.
- Two module depths and the flexibility of a modular sofa make corner, chaise, and open-end layouts easy to plan.
- The low 66 cm profile keeps a large configuration from blocking sightlines.

Who it is best for:
- People who regularly curl up, nap, or watch movies with their feet on the sofa.
- Open rooms that can absorb a 105 cm or deeper footprint without narrowing walkways.
- Buyers who prefer a soft, casual seat and do not mind reshaping loose cushions.
Where it falls short:
- The low back and deep seat provide limited upright support without an extra pillow.
- Down-and-feather cushioning needs more frequent fluffing than a firm foam seat.
- The 30 cm arms use substantial width that could otherwise become seating space.

Design and Materials
Cosima uses an FSC-certified wood structure with cold-foam support beneath a channel-sewn down-and-feather layer. The channel construction limits fill migration, but it does not eliminate the need to reshape the cushions. Current configurations offer changeable fabrics and traceable leather choices.
- Representative size: 246 cm W × 105 cm D × 66 cm H
- Seat height: 40 cm
- Seat depth: 72 cm on the representative configuration
- Armrest: 66 cm high and 30 cm wide
- Frame: FSC-certified wood
- Comfort layers: cold foam, down, and feather
- Warranty: 10 years, subject to Bolia's terms

Noora
Noora is the most adaptable sofa in this lineup. It looks tailored but does not feel stiff, and its two available module depths let buyers choose between everyday support and a much deeper lounge seat.
Our Testing Experience

The standard configuration gave us a 64 cm seat depth, 43 cm seat height, and 107 cm overall depth. It was deep enough to relax without forcing an upright sitter to reach for the backrest. The 127 cm modules are meaningfully different: their 84 cm seat depth moves Noora much closer to Cosima territory, so the module depth should be chosen before the fabric.
What we liked:
- The standard depth supports both conversation and feet-up lounging without feeling specialized.
- Foam, feather, and fiber layers provide a softer surface with more control than Cosima's looser fill.
- Two module depths make it easier to match the sofa to a room and a preferred posture.

Who it is best for:
- Households that need one sofa for conversation, reading, and casual lounging.
- People who want a deep seat but find Cosima's 40 cm seat height too low.
- Medium or large rooms where a modular layout will be used rather than simply filling space.
Where it falls short:
- Shorter sitters may still need a lumbar pillow on the 64 cm seat—and will almost certainly need one on the 84 cm version.
- The cushions need periodic reshaping because the construction includes feather and fiber, not foam alone.
- Leather versions do not have the changeable covers offered on fabric configurations.

Design and Materials
Noora combines a solid wood base with a layered seat containing polyurethane and cold foam, duck feather, and polyester fiber. The backrest also mixes foam and feather. That construction explains why it feels softer than a conventional foam sofa while holding the sitter more securely than Cosima.
- Representative size: 250 cm W × 107 cm D × 80 cm H
- Seat height: 43 cm
- Seat depth: 64 cm standard; 84 cm on 127 cm-deep modules
- Armrest: 60 cm high and 25 cm wide on the representative build
- Upholstery: changeable fabric covers; fixed upholstery on leather versions
- Seat construction: foam, duck feather, and polyester fiber
- Warranty: 10 years, subject to Bolia's terms

Caisa
Caisa looks lighter and more architectural than the other modular sofas here. The raised steel base exposes more floor, and its 91 cm overall depth is easier to place in a compact room than Cosima's or Noora's standard configuration.
Our Testing Experience

Caisa's 44 cm seat height and 20 cm legs made repeated sitting and standing easier than on the lower Cosima. Its 70 cm seat depth is not shallow, but the firmer feel and raised frame encourage a more active posture. At 73 cm tall, it stays visually compact even though the usable seat remains generous.
What we liked:
- The 91 cm overall depth is the easiest of these modular designs to fit near a walkway.
- The tall steel base makes the sofa look less bulky and leaves clear access beneath it.
- The supportive seat has the controlled feel people often seek in a firmer sofa, making it useful for reading, conversation, and short work sessions.

Who it is best for:
- People who prefer clear support over a loose, sink-in cushion.
- Smaller rooms that need a full three-seat width without an especially deep frame.
- Reading areas and living rooms where easy entry and exit matter.
Where it falls short:
- The 70 cm seat can still feel deep to shorter users, despite the sofa's compact overall depth.
- It lacks Cosima's enveloping softness and Noora's choice of two standard module depths.
- Buyers who nap often will be happier with a chaise or ottoman than with the straight sofa alone.

Design and Materials
Caisa uses an FSC-certified wood structure over a slim steel base. Open-end, corner, and chaise modules broaden the layout choices, while the high legs give the series its distinctive floating look. The original capacity figure has been removed because current product listings do not make its application to a complete sofa clear.
- Representative size: 242 cm W × 91 cm D × 73 cm H
- Seat height: 44 cm
- Seat depth: 70 cm
- Leg height: 20 cm
- Base: black-lacquered or brushed steel, depending on configuration
- Frame: FSC-certified wood and other controlled materials
- Warranty: 10 years, subject to Bolia's terms

Scandinavia
Scandinavia has the most conventional proportions in this group, which is precisely why it works for so many households. It supports an upright position without feeling formal, and its separate reversible cushions are easier to rotate than fixed or highly sculpted seats.
Our Testing Experience

The representative sofa combines a 58 cm seat depth, 45 cm seat height, and 92 cm overall depth. That geometry let more sitters use the backrest while keeping their feet planted. It was also the easiest model to leave after a long sit, though people who routinely curl up will find the straight seat less accommodating than Cosima or deep Noora modules.
What we liked:
- The familiar seat height and depth work across a wider range of body types.
- Reversible cushions spread wear and make routine upkeep more useful.
- Buyers can choose down-and-feather cushions for softness or foam for firmer support.

Who it is best for:
- Families with sitters of different heights and different comfort preferences.
- Anyone who wants an easy everyday sofa rather than a low, dedicated lounge platform.
- Buyers who value reversible cushions and removable fabric upholstery.
Where it falls short:
- The 58 cm seat does not leave as much room for curling up as Cosima or deep Noora modules.
- The classic loose-cushion profile looks less minimal than Caisa's raised steel frame.
- Down-filled versions still need regular fluffing; choose foam if low maintenance matters more than softness.

Design and Materials
Scandinavia uses an FSC-certified wood interior structure, removable fabric upholstery, reversible cushions, and a stainless-steel base. Cushion fill is a choice rather than a single series-wide specification: down and feather produce a softer seat, while foam holds a tidier shape.
- Representative size: 236 cm W × 92 cm D × 78 cm H
- Seat height: 45 cm
- Seat depth: 58 cm
- Leg height: 13 cm
- Base: stainless steel
- Comfort choices: down and feather or foam
- Warranty: 10 years, subject to Bolia's terms

How We Compared These Sofas
We used the same evaluation framework for all four sofas so the tradeoffs stayed visible. Published dimensions were checked against the exact representative configurations rather than treated as universal measurements for an entire series.
Each sofa received a score out of five for comfort and ergonomics, cooling and breathability, durability and build, cleaning and maintenance, and value and warranty. The overall score reflects the full experience rather than a simple average.
We also compared how the seat supported upright and relaxed postures, how easily a sitter could stand, how much cushion upkeep the fill required, and how large each configuration felt in a room.
- Comfort and Ergonomics: seat geometry, back support, pressure distribution, and comfort over a long sit.
- Cooling and Breathability: fabric airflow and heat buildup over time.
- Durability and Build: frame stability, seam quality, cushion resilience, and moving parts.
- Cleaning and Maintenance: cover handling, stain visibility, care requirements, and reshaping.
- Value and Warranty: useful customization, warranty terms, and performance for the price tier.
How the Four Sofas Scored
The scores below use one five-point scale. Small differences matter less than the pattern: Cosima leads for soft lounge comfort, Scandinavia for broad everyday usability, Noora for flexibility, and Caisa for a compact, supportive layout.
| Category | Cosima | Noora | Caisa | Scandinavia |
|---|---|---|---|---|
| Comfort and Ergonomics | 4.4 | 4.2 | 4.1 | 4.3 |
| Cooling and Breathability | 4.1 | 4.0 | 4.1 | 4.2 |
| Durability and Build | 4.2 | 4.1 | 4.2 | 4.3 |
| Cleaning and Maintenance | 4.0 | 4.0 | 3.8 | 4.0 |

| Overall Score | 4.3 | 4.2 | 4.1 | 4.2 |
What Should You Look For?
Start with seat and overall depth. Cosima's 72 cm seat is designed around reclining, while Noora lets you choose between 64 and 84 cm. Caisa has a generous 70 cm seat inside a compact 91 cm frame, and Scandinavia's 58 cm seat best supports a conventional upright posture.
Next, decide how much cushion maintenance you will tolerate. The choice between down and foam sofa cushions changes both softness and upkeep: down and feather need reshaping, while foam holds a cleaner outline. Mixed constructions such as Noora sit between those extremes.
Finally, check the exact upholstery and layout. A removable cover is useful only if its care instructions suit your routine, and knowing how to choose a modular sofa helps ensure the pieces support the room's traffic pattern.
- Seat depth: match it to upright sitting, feet-up lounging, or both.
- Cushion fill: choose soft down, structured foam, or a mixed construction.
- Cover system: verify removability and care for the exact upholstery.
- Room fit: measure the complete configuration, not one module or a catalog photograph.
- Daily use: prioritize the posture and activity the sofa will support most often.
How Bolia Compares With Similar Sofas
HAY Mags Soft is the closest alternative to Cosima. Both are low, deep, and modular, but Mags Soft uses a high-density foam structure with extra padding, giving it a more controlled surface. Cosima feels looser and softer because of its down-and-feather comfort layer. Choose HAY for a cleaner foam feel; choose Cosima for a softer seat and more casual cushion shape.
Muuto Outline suits the buyer drawn to Caisa's or Scandinavia's cleaner posture. It wraps a deep cold-foam seat in a slim architectural shell, and the Studio versions reduce overall depth for tighter rooms. Outline looks sharper and more formal than Noora or Cosima, but it offers less of their loose, sink-in character.
Room & Board Metro is a practical U.S.-market comparison. The 88-inch version has a 38-inch overall depth, 22-inch seat depth, and 17-inch seat height, close to familiar American living-room proportions. It offers many sizes and fabrics, but its appeal is broad everyday comfort rather than Bolia's distinctly low European modular look.
What Changes by Configuration?
Every dimension in this guide belongs to a representative configuration. Module choice can change width, overall depth, usable seat depth, arm placement, and the way a sofa fits a room, which is why it helps to measure a sectional layout as a complete unit. Noora shows why this matters: its standard and deep modules have 64 cm and 84 cm seat depths, respectively.
Upholstery also changes the experience. A dense wool, open weave, velvet, and leather can feel different in temperature, grip, and firmness on the same cushion. A removable or changeable cover does not guarantee machine washing, and Noora's leather versions do not use its changeable fabric-cover system.
- Confirm every dimension for the exact module plan before ordering.
- Use a fabric sample to judge color, texture, and surface warmth in the room.
- Read the care label for the chosen upholstery instead of relying on the series description.
Before You Order a Bolia Sofa
A few checks will prevent most expensive surprises:
- View fabric samples in daylight and evening light before choosing a color.
- Mark the complete width and depth on the floor, including open ends and chaises.
- Plan delivery and setup around doorway, stair, elevator, and module dimensions, and measure the delivery path before ordering.
- Check care instructions for the exact fabric; removable does not always mean washable.
- Choose the seat depth around the shortest regular sitter, then add an ottoman if deeper lounging is occasional.
FAQs
Are Bolia sofas easy to assemble?
Setup is generally straightforward, and several Noora configurations arrive without assembly. The harder part is moving large or heavy modules into position. Compare package dimensions with doors, stairs, and elevators before delivery.
Do Bolia sofas have removable covers?
Many current fabric configurations use removable or changeable upholstery, but the system and care instructions vary. Noora's leather versions do not have changeable covers. Confirm the exact upholstery specification before ordering.
Are Bolia sofas worth the price?
They make the strongest case for buyers who will use the customization, distinctive proportions, and 10-year warranty. If you want a standard-size sofa in a basic fabric, a less specialized brand can deliver similar everyday comfort for less.
How long should a Bolia sofa last?
There is no honest single lifespan because use, fill, and upholstery matter. Bolia's current 10-year warranty covers material and workmanship defects under its terms, not normal wear or improper care. Reversible cushions, changeable fabric covers, and routine maintenance can extend useful life.
Which Bolia sofa is best for a small apartment?
Caisa is the easiest modular option to place because the representative configuration is 91 cm deep and stands on 20 cm legs. Scandinavia is also manageable at 92 cm deep. Cosima and Noora can work among other apartment sofas, but their deeper modules need careful floor planning.
