HKM-036115
Ergonomic Adjustable High Back Leather Recliner
Precision-crafted for exceptional comfort, superior support, and effortless mobility — engineered for the modern workspace.
Designed Around You
Every element of the HKM-036115 has been thoughtfully engineered to deliver an unparalleled seating experience. From the premium upholstery to the adaptive ergonomics, this chair transforms how you sit, work, and recharge.
Premium Leather Upholstery
High-quality leather delivers a refined aesthetic while offering exceptional durability and a soft, supple feel that improves with time.
High Back Spinal Alignment
The extended backrest cradles your upper body, promoting natural spinal curvature and reducing cumulative strain during extended sessions.
Adjustable Recline Mechanism
Fine-tune the seat angle and height to match your body's preferences. One intuitive control lets you shift from focused work to relaxed recline.
360° Swivel Base
Effortless rotation keeps you agile in dynamic environments. Reach across your desk, collaborate with colleagues, or pivot to a new view without strain.
Refined Leather, Lasting Impression
The leather upholstery on the HKM-036115 is selected for its balance of luxury and resilience. Unlike fabric alternatives that can pill or fade, quality leather develops a distinguished patina over time, telling the story of your work while maintaining a consistently professional look. The surface is also easy to clean — a simple wipe with a damp cloth keeps it looking pristine, making it an ideal choice for both home offices and corporate settings where presentation matters.
Timeless Durability: Leather outlasts most fabric upholstery by a factor of 3–4× in high-use environments, making it a sound long-term investment.
The Science of Supportive Sitting
Prolonged sitting in poorly designed chairs contributes to musculoskeletal discomfort, reduced circulation, and cumulative fatigue. The HKM-036115 addresses these challenges head-on with a high back structure that mirrors the natural S-curve of the human spine. By distributing body weight evenly across the backrest, pressure points are minimized, and the lumbar region receives consistent, gentle reinforcement. Studies in occupational health consistently highlight that chairs promoting neutral spine posture can reduce reported back discomfort by up to 30% during an 8-hour workday when compared to non-ergonomic alternatives.
Upper Body Focus: The high back supports the thoracic and cervical spine, reducing shoulder hunch and neck forward-tilt — common issues in screen-based work.
Pressure Distribution: The contoured backrest disperses body mass across a wider surface area, alleviating concentrated stress on the lower back discs.
Personalized Precision Adjustment
No two bodies are alike, which is why the HKM-036115 puts customization at your fingertips. The seat height adjusts smoothly across a generous range — approximately 17.7–21.7 in (45–55 cm) from the floor — accommodating users of varying statures. Meanwhile, the recline tension can be set to your preferred resistance level, allowing you to lean back comfortably without feeling unsupported. Whether you prefer an upright, task-focused posture or a gently reclined angle for contemplative reading, this chair adapts instantly.
Smooth Height Adjustment: A Class-4 gas lift cylinder — the industry benchmark for reliability — ensures fluid, quiet height transitions rated for over 100,000 cycles of daily use.
Effortless 360° Mobility
The swivel base transforms your workspace into a fluid, responsive environment. In fast-paced office settings, the ability to rotate without repositioning your entire chair saves time and reduces micro-interruptions. The base is constructed from reinforced nylon with a wide 27.6 in (70 cm) diameter footprint that provides exceptional stability — even when fully reclined. Smooth-rolling casters glide across hardwood, tile, and low-pile carpet, while their scratch-resistant coating protects delicate flooring surfaces.
Floor-Friendly Casters: Dual-wheel nylon casters with a soft polyurethane tread ensure silent rolling and protect hardwood, laminate, and tile from scuffs and scratches.

Investing in Your Daily Well-Being
Modern knowledge workers spend an average of 6.5 hours per day seated — and that figure climbs higher for remote professionals and executives. Over a career spanning decades, the cumulative impact of suboptimal seating can manifest as chronic back pain, reduced mobility, and even circulatory concerns. The HKM-036115 is designed not as a mere piece of office furniture but as a proactive wellness tool. By supporting the body's natural alignment, it helps mitigate the long-term risks associated with sedentary work patterns. When paired with regular movement breaks and a height-appropriate desk, this chair becomes a cornerstone of a healthier, more sustainable work routine.
Ergonomic Certification Standards: The design aligns with guidelines established by occupational health authorities, including recommended seat depth-to-thigh clearance ratios and lumbar curvature support benchmarks.
Frequently Asked Questions
What type of leather is used in the HKM-036115?
The HKM-036115 features premium bonded leather upholstery that combines genuine leather fibers with a durable polyurethane backing. This construction offers the look and feel of traditional leather at a more accessible price point while providing enhanced resistance to peeling and cracking. The surface is treated with a protective coating that repels minor spills and resists UV fading, making it suitable for bright office environments.
How does the recline mechanism work, and what is the maximum recline angle?
The chair utilizes a tilt-tension mechanism located beneath the seat pan. By rotating the tension knob clockwise, you increase the resistance required to recline; counterclockwise rotation decreases it. The backrest reclines to a maximum angle of approximately 135 degrees relative to the seat, allowing for a comfortable reclined position without compromising stability. The seat angle remains relatively stable during recline, which helps maintain proper thigh support.
Is the chair suitable for users taller than 6 ft (183 cm)?
Yes. The high back design — measuring approximately 29.5 in (75 cm) from the seat surface to the top edge — provides ample support for users up to approximately 6 ft 4 in (193 cm). The adjustable seat height range of 17.7–21.7 in (45–55 cm) accommodates a wide variety of leg lengths. For users at the upper end of this range, we recommend pairing the chair with a footrest if the desk height cannot be adjusted to maintain a 90-degree knee angle.
What tools are required for assembly?
The HKM-036115 ships with all necessary hardware and a detailed illustrated manual. Assembly requires only the included hex key — no power tools or additional equipment are needed. Most users complete the process in approximately 20–30 minutes. The package includes pre-installed components where possible to minimize assembly steps, and all bolts feature pre-applied thread-locking compound to prevent loosening over time.
Can the swivel base be locked in a fixed position?
The swivel function is permanently enabled to maximize flexibility and ease of movement. This design choice reflects the chair's intended use in dynamic work environments where frequent rotation is beneficial. If you require a fixed-position chair for specific tasks, we recommend considering a stationary-base model. However, the swivel action is smooth and controlled — it will not spin freely without intentional user input.
How should I maintain and clean the leather upholstery?
Routine maintenance is straightforward. Wipe the leather surface weekly with a clean, slightly damp microfiber cloth to remove dust and light soiling. For deeper cleaning, use a pH-neutral leather cleaner applied to a cloth — never directly onto the leather — and gently buff in circular motions. Avoid harsh chemical cleaners, saddle soaps, or abrasive pads, as these can damage the protective topcoat. Conditioning every 4–6 months with a water-based leather conditioner helps preserve suppleness and sheen.
