Who it fits

Key specs explained for you

Safety Certifications: BIFMA

This chair meets BIFMA safety standards. These guidelines test for stability, durability, and structural integrity under normal use. You get assurance that the frame and mechanisms are built to hold up over time. This certification is a baseline for office furniture quality. It helps you avoid chairs that might wobble or fail during daily sitting. It is a practical check for long-term reliability in your workspace.

Seat Cushion Type: memory foam and ComfortCoils

The seat combines memory foam with ComfortCoils. Memory foam contours to your body shape, reducing pressure points. The coils add support and prevent the foam from bottoming out completely. This mix aims to balance softness with firmness. You benefit from plush comfort that still supports your posture. This is distinct from standard foam or mesh seats, offering a unique feel for long hours.

Upholstery Material: vegan leather

The chair uses vegan leather for its surface. This material mimics the look and feel of traditional leather without using animal products. It is often easier to clean and maintain than fabric. You get a smooth surface that resists spills. This option suits those who prefer a sleek aesthetic or want to avoid animal-derived materials. It is a common choice for modern office environments.

Back Style: High Back

This is a high-back design, meaning the backrest extends above your shoulders. It provides support for your entire spine, including the upper back and neck. You get full coverage rather than just lumbar support. This style is common in executive chairs. It helps maintain proper posture by encouraging your back to rest against the full surface. It is ideal if you need comprehensive support during long work sessions.

Design and build overview

The listing describes the Serta SmartLayers Mosby as a high-back executive chair. It uses vegan leather upholstery. This material offers a smooth, premium look while remaining easier to maintain than animal leather. The surface is perforated to allow air flow, which helps keep you cool during long work sessions. The color scheme combines blue and dark gray tones for a modern aesthetic that fits well in professional environments.

According to the listing, the seat cushion uses a blend of memory foam and ComfortCoils. This combination aims to provide plush support while maintaining structure. The chair also features a padded headrest and horizontal armrests. These elements are designed to support an engaged posture. The AIR Ergonomic Support Technology allows the chair to pivot smoothly as you move, adapting to your shifts in position without resistance.

In terms of physical dimensions, the chair measures 30.8 inches in length, 17.3 inches in width, and 25.5 inches in height. It weighs 54.8 pounds. This substantial weight suggests a sturdy frame capable of supporting regular daily use. The BIFMA certification indicates that the structure meets specific safety and durability standards.

You will assemble this Serta SmartLayers Mosby chair using the included hardware. The listing does not specify the exact tools required, but standard Allen keys are typically provided for high-back office chairs. You will attach the base to the gas lift cylinder, then mount the seat mechanism. The seat cushion integrates memory foam and ComfortCoils. This layered construction requires no special setup beyond standard mechanical assembly. You will connect the armrests to the seat frame. The horizontal armrests are padded to support your forearms. They are fixed in position according to the provided features. There are no adjustable armrest specifications listed. You will position the chair on a flat surface. The chair pivots using AIR Ergonomic Support Technology. This mechanism allows the backrest to move with your body. You do not need to adjust tension manually for this pivot action.

Before You Buy This Chair

Before you add this chair to your setup, check your desk dimensions. The listed width is 17.3 inches and the length is 30.8 inches. Ensure your workspace can accommodate this footprint without crowding other furniture. You should also verify floor compatibility. At 54.8 pounds, the base is sturdy, but hard floors may require a protective mat to prevent scratches during movement. Upholstery care is straightforward. The perforated vegan leather wipes clean with a damp cloth, avoiding harsh chemicals that could damage the material. Since the seat uses memory foam and ComfortCoils, avoid sitting on the armrests or edges, which can compress the foam unevenly over time. This model fits well if you prefer a high-back executive style with breathable support. Compare its BIFMA certification and specific cushioning layers against other options in our guide to see if its weight and size align with your daily needs.

Check before you buy

• Verify your desk width can fit the 17.3-inch armrest span.
• Check floor type for potential scratches from the heavy base.
• Confirm the high-back height suits your monitor viewing angle.
• Ensure you have space for the 30.8-inch total length.
