Mantle Jasper 110‘’ Sofa Review

The Jasper earns its 4.1/5 score by doing one job especially well: it provides a long, uninterrupted place to lounge while keeping a crisp, modern shape. The 25-inch seat depth makes it easy to sit cross-legged or stretch out, and the bench cushion avoids the hard seams that can get in the way when two people share the sofa. The frame stayed quiet and steady, and the cushion regained its shape quickly after long sessions.

Buy it for relaxed sitting, not as a substitute for an upright reading chair. Smaller users will probably want a lumbar pillow, and the Classic Velvet on our test unit held more heat than a breathable woven fabric. The 110-inch version currently starts at $3,290 before fabric and cushion upgrades, so the Jasper makes the most sense when its exact combination of length, depth, and tailored styling is what you want.

Who it suits

• Tall or long-legged people who want to stretch out without using a chaise

• Couples who prefer one shared seat instead of divided cushions

• Large living rooms with enough wall length and open walking paths

Who should look elsewhere

• Petite users who prefer a shallow, upright seat

• Anyone who runs hot or plans to place the sofa in a consistently warm room

• Buyers who need a compact sofa or want a softer, sink-in feel

For two workweeks, the Jasper served as the main sofa for movie nights, laptop work, short naps, and everyday sitting. Following our sofa-testing process, we measured the frame and usable seat, checked how far the cushion compressed at the center and edge, timed its recovery, and tracked surface temperature during an hour-long sit. We also watched for frame noise, shifting, uneven wear, and visible nap marks, then vacuumed and spot-cleaned the velvet to see how much routine upkeep it needed. Delivery and value scores reflect the standard white-glove service, the current configuration price, and Mantle's published return and warranty terms.

The Jasper naturally pulled us toward the middle of its bench cushion. Starting upright with a laptop usually turned into a half-reclined position within 30 minutes, which felt comfortable but confirmed that the sofa favors lounging over desk-like posture. Our frame measured 109.8 inches wide, close to the listed 110 inches, and the full 25-inch seat depth left plenty of room to bring both legs up. A small lumbar pillow made a noticeable difference when we wanted to sit straight for more than an hour.

After a 60-minute sit, the cushion compressed 1.4 inches at the center and 0.9 inch near the edge. It recovered about 96% of its original height within five minutes, with no ridge or low spot left across the bench. The frame did not creak or shift, and the center support kept the long seat feeling even when two people sat at opposite ends.

The Classic Velvet upholstery was the more demanding part of the test. Its surface temperature rose 6.7°F during an hour-long gaming session, and the nap showed handprints and pressure marks afterward. A soft upholstery brush reset the surface in a few passes, but this is not a fabric that looks untouched without regular care. By the end of the second week, the cushion remained level and the tailored outline still looked clean.

What we liked

• The continuous bench cushion gives two people room to shift positions without landing on a seam.

• The seat is deep enough for tucked-leg lounging, yet its edges stay supportive when standing up.

• Fast cushion recovery and a quiet frame helped the sofa keep its tailored shape throughout the test.

Who it is best for

• Tall users and anyone who spends more time reclining than sitting bolt upright

• Couples who want a shared lounging surface with no center cushion gap

• Hosts who need substantial seating but still want a clean, composed silhouette

Where it falls short

• The tested velvet built up noticeable warmth during an hour-long sit.

• A 110-inch frame leaves little flexibility in small rooms or around narrow traffic paths.

• The 25-inch depth makes sustained upright work less comfortable without added lumbar support.

• Price: from $3,290 for the 110-inch configuration at the time of verification; fabric, cushion, and add-on choices change the total

• Dimensions: 110" W × 36" D × 31" H

• Seat: 25" deep and 18" high; 24" arm height

• Cushions: one bench seat and three back cushions; center support leg on the 110-inch size

• Tested upholstery: Classic Velvet in Currant; check current swatches and availability before ordering

• Construction: engineered-hardwood frame with 8-way hand-tied springs

• Cushioning: CertiPUR-certified foam wrapped in fiber, with fiber-filled backs

• Delivery: white-glove service; Mantle currently estimates 2–4 weeks for production before transit

• Returns and warranty: standard orders have a limited return window, while sale, Ready-to-Ship, and custom orders are final sale; the frame and spring system are covered for the useful life of the sofa

Start with how you sit. The 25-inch seat works best for curling up, sitting cross-legged, and leaning back for a movie. If you prefer to keep both feet flat on the floor with your back against the cushion, test a similarly deep sofa first or plan to add a lumbar pillow.

Next, tape out the full 110-by-36-inch footprint and leave enough room for the walking path you use every day. Measure doors, elevators, stair turns, and the final approach to the room as carefully as the wall itself because the sofa ships in one piece. Order upholstery swatches, view them in daytime and evening light, and compare their care requirements. Finally, confirm the exact return category on your order: standard pieces have a limited return window, but sale, Ready-to-Ship, and custom orders are final sale.

If you want a medium-depth sofa that supports more upright sitting, the Room & Board Metro is the better all-purpose choice. If a deep bench cushion matters most, the Crate & Barrel Gather Deep Bench is the closer layout match.

Scale is the first constraint. At 110 inches wide, the Jasper can crowd a small room and make a narrow delivery route difficult. The deep seat is also less versatile than it first appears: it is excellent for lounging, but shorter users may need a pillow behind their back for upright sitting. Classic Velvet on our test unit felt warm and showed nap marks after use, so buyers who want a cooler, low-maintenance surface should compare other upholstery options. A bench cushion also needs regular rotation from end to end to spread wear, and Mantle notes that comfort wrinkles can develop over time.

The Jasper stands apart through its combination of a 110-inch frame, a relatively trim 36-inch overall depth, a 25-inch usable seat, and traditional 8-way hand-tied springs. The alternatives below cost less in their current base configurations, but each changes the sitting experience in a meaningful way.

Room & Board Metro

The standard 88-inch Metro is 38 inches deep with a 22-inch seat and currently starts around $2,199 in the displayed fabric. It is shorter, easier to place, and more supportive for upright sitting than the Jasper. Choose the Metro when several people with different body sizes will use the sofa every day; choose the Jasper when uninterrupted lounging space and a bench cushion matter more.

Crate & Barrel Gather Deep Bench

The current 89-inch Gather Deep Bench starts at $2,099 and measures 43 inches deep. Like the Jasper, it offers a continuous seat, but its inner-coil cushion and sinuous-wire suspension create a plusher, more casual feel. It is the closest alternative for bench-seat fans who want a deep sofa, though the Jasper gives you more width, a shallower overall footprint, and a more tailored outline.

Crate & Barrel Lounge Deep

The 93-inch Lounge Deep starts at $2,349 and measures 46 inches deep. It is the clear choice for maximum sink-in comfort and sprawling, but its divided cushions and softer profile look more relaxed. The Jasper is better when you want a deep usable seat without giving nearly four feet of floor depth to the sofa.

• Confirm the entire delivery path, including doorways, hall turns, elevators, and stair landings, before ordering.

• Keep a slim lumbar pillow nearby for laptop work or other upright sitting.

• Use light throws if you run warm, especially with velvet upholstery.

• Vacuum velvet with a soft upholstery attachment and brush the nap in one direction.

• Blot spills promptly and follow the cleaning code for the exact fabric you order.

• Rotate the bench cushion from end to end to distribute compression.

• Pair the sofa with a slim ottoman if you want occasional leg support without adding a permanent chaise.

• Use a stable side table or tray for drinks rather than balancing them on the seat.

• Offer shorter guests a back pillow so they can reduce the usable seat depth.
