Interior Define is a strong choice when an off-the-shelf sofa is almost right but the size, depth, fabric, or cushion fill is not. We tested four of the brand’s best-known sofas in everyday living-room use, moving between laptop work, reading, conversation, and long movie sessions. Sloan was the best all-around performer. Jasper favored a laid-back posture, Gaby gave side loungers the most support, and Maxwell was the clear pick for sinking in. The main drawbacks are long lead times, costly returns, and prices that rise quickly as you customize.
Product Overview
| Sofa | Overall Score | Pros | Cons | Best For | Tested Price |
|---|---|---|---|---|---|
| Sloan Sofa | 4.2/5 | Balanced comfort; supportive front edge; versatile proportions | Not modular; upgrades add up quickly | Mixed-use rooms, casual work, and movie nights | $1,912.50 |
| Jasper Sofa | 4.0/5 | Relaxed sit; crisp low profile; easy to stretch out on | Low back needs extra lumbar support for upright sitting | Minimalist rooms, reading, and relaxed TV use | $2,193.75 |
| Gaby Sofa | 4.0/5 | Useful side cushions; tidy shape; stable edge support | Less plush than Maxwell; velvet holds heat | Readers, side loungers, and design-focused rooms | $2,130 |
| Maxwell Sofa | 4.0/5 | Softest sit; low, relaxed posture; excellent for stretching out | Lowest seat; large footprint; warmest tested upholstery | Media rooms, couples, and long movie nights | $1,676.25 |
Testing Team Takeaways
Sloan was the easiest sofa to live with because it handled upright sitting and lounging equally well. Jasper had the lowest back and encouraged us to lean back, while Maxwell had the lowest seat and the softest, most relaxed posture. Gaby landed between them: more contained than Maxwell, but better for curling up than Sloan because its side cushions gave us a natural place to lean. For most homes, we would choose Sloan. For a dedicated media room, Maxwell was more comfortable.

How We Tested It
We put each sofa through the same living-room routine: laptop sessions, reading, conversation, and movie nights. We scored assembly, cooling, comfort, durability, layout practicality, cleaning, and value on a 5-point scale. We also measured each test unit, recorded unloaded seat height, compared center and edge cushion compression, and tracked the change in surface temperature after a 60-minute sit. Comfort scores reflected how well each sofa supported different postures over time, not how soft it felt in the first few minutes.
Delivery, Lead Time, Returns, and Warranty
Interior Define’s made-to-order model gives you far more control than most ready-made sofas, but the order terms deserve close attention. These were the terms shown with the configurations we tested; confirm the final details in your cart because timing, fees, and coverage can change.
-
Delivery: In-home white-glove delivery was available for the tested orders.
-
Estimated lead time: The listings quoted 8–12 weeks, though custom orders can take longer.
-
Returns: Made-to-order upholstered returns initiated within 60 days were subject to a 50% processing fee, with original shipping charges generally nonrefundable.
-
Warranty: A 10-year limited warranty covered qualifying manufacturing defects in the frame and suspension system for the original owner and delivery address.
Interior Define Sofas: Our Testing Experience
Sloan Sofa
Our Testing Experience

Sloan was the sofa we chose most often when the evening included both laptop time and a show. Our test unit measured 91 x 36 x 35 inches, and its 19-inch seat height let most testers keep their feet flat without sitting bolt upright. Under our standard load, the center of the cushion compressed 1.5 inches while the front edge compressed 0.8 inch. That firmer edge made repeated stand-ups noticeably easier than on Maxwell.

The chenille also handled long sessions better than the three velvet test fabrics. Its surface rose 3.4°F after 60 minutes, the smallest increase in the group. Motion still traveled across the shared cushions when a second person shifted, but the seat recovered its shape without constant fluffing. Those results match Sloan’s 4.4/5 comfort and 4.1/5 cooling scores and explain why it earned the highest overall rating.
What we liked

The most natural balance between upright support and relaxed comfort

A firm front edge that helps when standing up frequently

Jasper Sofa
Our Testing Experience

Jasper’s low back looked sharp and kept the 84 x 36 x 28-inch test unit from feeling visually heavy. Its seat was 17 inches high—low, but still one inch higher than Maxwell’s. Once seated, we naturally leaned back. The cushion compressed 1.8 inches at the center and 1.0 inch at the edge, giving it a softer first impression than Sloan without the same sense of sinking.

That posture worked well for reading and TV, but it was less convincing for a full laptop session. After about an hour upright, taller testers wanted a small lumbar pillow, which lines up with Jasper’s 3.8/5 back-support score. The performance velvet warmed by 4.7°F over the same hour and showed directional marks where clothing brushed the pile. Neither issue ruined the experience, but both were more noticeable than on Sloan’s chenille.
What we liked
-
A clean, low profile that does not dominate the room
-
Soft cushions that feel comfortable quickly
-
An open seat that makes it easy to recline or stretch out

Who it is best for
-
People who usually read, recline, or watch TV instead of sitting upright
-
Modern or minimalist rooms that suit a low silhouette
-
Households that prefer soft, casual comfort
Where it falls short
-
The low back does not support long, desk-like sitting as well as Sloan
-
Taller users are more likely to need a lumbar pillow
-
Velvet holds more heat and shows brush marks between cleanings

Gaby Sofa
Our Testing Experience

Gaby felt purpose-built for people who sit sideways or curl up with a book. The 88 x 36 x 33-inch test unit had an 18-inch seat height, and its attached side cushions gave our shoulders a steady place to rest without adding a loose pillow. The center compressed 1.4 inches under load and the edge 0.8 inch, so the seat felt controlled and supportive rather than pillowy.

That structure helped the sofa stay tidy after everyday use and supported Gaby’s 4.2/5 comfort and durability scores. The compromise was heat. Its performance vintage velvet rose 4.9°F after 60 minutes, and the pile changed direction where we leaned. We would still choose Gaby over Jasper for side lounging because the built-in support reduced how often we had to adjust our position.
What we liked
-
Side cushions that genuinely help during reading and curled-up sitting
-
Stable center and edge support without a firm, formal feel
-
A tailored shape that stays neater than Maxwell after use

Who it is best for
-
Readers and side loungers who rely on an arm or cushion for support
-
People who want a contained seat instead of a wide-open sprawl
-
Design-focused rooms that still need practical daily comfort
Where it falls short
-
It does not deliver Maxwell’s deep, sink-in feeling
-
The velvet becomes noticeably warmer during long, still sessions
-
Its track arms and side cushions leave less room for unrestricted lounging

Maxwell Sofa
Our Testing Experience

Maxwell gave us the most relaxed posture of the four. Our deep test configuration measured 86 x 42 x 31 inches, and its 16-inch seat was the lowest in the group. The cushion dropped 2.1 inches at the center and 1.2 inches at the edge under load. That softness explains its group-leading 4.5/5 comfort score, but it also made standing up slower than it was on Sloan or Gaby.

The 42-inch overall depth changed the room more than the other sofas did, so we had to protect the walkway in front of it. Once settled, though, Maxwell was the clear favorite for couples and long movie sessions. Its Mod velvet warmed by 5.3°F after an hour, the highest increase we recorded, and laptop use never felt natural because the low, soft seat kept pulling us away from an upright position.
What we liked
-
The softest, most comfortable seat for long viewing sessions
-
Enough room to recline and change positions without feeling boxed in
-
A relaxed shape that works especially well for couples

Who it is best for
-
People who care more about lounging than upright support
-
Media rooms with enough depth to preserve clear walkways
-
Anyone who likes a low seat and noticeable cushion sink
Where it falls short
-
The 16-inch seat is harder to rise from, especially if you stand often
-
The deep configuration takes up considerably more floor space
-
Its velvet held the most heat during our hour-long test

Compare Performance Scores of These Sofas
| Sofa | Overall | Seat Comfort | Back Support | Depth Fit | Cooling | Durability | Repositioning |
|---|---|---|---|---|---|---|---|
| Sloan Sofa | 4.2/5 | 4.4/5 | 4.2/5 | 4.3/5 | 4.1/5 | 4.3/5 | 3.9/5 |
| Jasper Sofa | 4.0/5 | 4.3/5 | 3.8/5 | 4.0/5 | 3.8/5 | 4.1/5 | 4.0/5 |

| Maxwell Sofa | 4.0/5 | 4.5/5 | 4.0/5 | 4.0/5 | 3.6/5 | 4.1/5 | 3.7/5 |
Sloan’s 4.2/5 overall score reflects its consistency: it never led by a huge margin, but it created the fewest compromises. Maxwell earned the top comfort score and the lowest cooling score, making it ideal for lounging but less versatile. Jasper’s 3.8/5 back-support result confirms that its low profile works better for reclining than for a workday. Gaby’s strongest results came from comfort, depth fit, and durability, which suits readers who want a stable place to lean.
How to Choose an Interior Define Sofa
Choose the posture before the fabric. If you regularly sit upright for conversation, sports, or laptop use, favor a higher seat, a supportive front edge, and a back that reaches your lower shoulder blades. Sloan was the best match for that routine. If you mostly recline, Maxwell’s low seat and softer cushions are more comfortable, but its tested 42-inch depth needs careful planning.
Your height matters as much as the room. Petite sitters often feel more stable on Gaby because its side support keeps the seating area contained. Taller loungers may prefer Maxwell’s open posture, while taller people who sit upright should be cautious with Jasper’s low back. Before ordering, tape the full width and depth on the floor, then walk the route from the entry door to the final room. Interior Define offers many configurations, but a custom sofa still has to clear every turn along the delivery path.
Limitations
Customization is the reason to buy from Interior Define, but it also makes comparison shopping harder. The dimensions and prices in this review belong to the configurations we tested; changing the width, depth, cushion fill, fabric, or legs can change the price and the way the sofa sits. Lower backs such as Jasper’s are less supportive for long upright sessions, and Maxwell’s low, soft seat is harder to leave quickly. None of these four works like a true modular system, and the 50% return processing fee makes a measurement mistake unusually expensive.
Interior Define Sofas vs. Alternatives
Interior Define makes the most sense when you want a conventional sofa silhouette with unusually specific control over width, depth, fabric, legs, and cushion fill. Sloan and Gaby show the advantage clearly: both look tailored, yet their standard and deep options can accommodate different rooms and sitting habits.
Lovesac Sactionals: Choose Sactionals if you expect to move, rearrange the room often, or need removable machine-washable covers. The system is far more flexible than any sofa in this review, but setup takes longer and the modular seams create a busier look.
Room & Board Metro: Metro is the better alternative for a consistently upright sit. It offers multiple sizes and depths, has a conventional 17-inch seat height, and feels easier to use for conversation or laptop work. Interior Define offers more aesthetic customization, while Metro requires fewer decisions and has a more predictable posture.
Crate & Barrel Lounge Deep: The Lounge Deep 83-inch Sofa is the closest alternative to Maxwell’s relaxed feel. Its 46-inch overall depth is even more demanding, but it delivers a broad, plush seat and is easier to try in a store. Choose Maxwell when custom upholstery and a lower profile matter; choose Lounge Deep when maximum depth and showroom access matter more.
Pro Tips for Interior Define Sofas
-
Mark the full width and depth with painter’s tape, then check the remaining walkway from every doorway.
-
Order fabric swatches and view them in morning, afternoon, and evening light before choosing.
-
If you work from the sofa, plan on a small lumbar pillow for Jasper and Maxwell.
-
Rotate seating positions during the first few weeks so one cushion does not take all the early wear.
-
Brush or vacuum velvet with the pile to even out pressure marks and directional shading.
-
Check the final price after every customization; upholstery and cushion upgrades can change the total more than expected.
-
Save a screenshot of the selected dimensions, lead-time estimate, return terms, and warranty before placing the order.
FAQs
Which Interior Define sofa felt most balanced day to day?
Sloan was the easiest sofa to use for upright sitting, casual work, conversation, and relaxed viewing. Its 19-inch seat and supportive front edge made changing positions and standing up easier than on the lower models.
Which one is best for long movie nights?
Maxwell was the most comfortable for long movie sessions. Its low seat and soft cushions encouraged a relaxed posture, though the deep configuration used more floor space and held more heat.
I’m petite—what’s the safest pick?
Gaby is the safest starting point for petite sitters because its 18-inch seat and side cushions create a more contained, supported position. Sloan is the better alternative if easy stand-ups matter more than curling up.
Which sofa runs warmest in extended sitting?
Maxwell ran warmest in our test, with a 5.3°F surface-temperature increase after 60 minutes. Gaby and Jasper followed closely, while Sloan’s chenille recorded the smallest increase at 3.4°F.
