Belmont Quolis Q5500

The Belmont Quolis Q5500 Dental Chair is a premium patient chair designed for practices that want refined hydraulic movement, intuitive controls, close clinical access, and a high level of patient comfort. Its slim, contoured backrest, dual-articulating headrest, integrated touchpads, and soft-start/soft-stop hydraulic system provide precise control throughout patient positioning.

Every major adjustment is designed to support an efficient treatment workflow. Controls beneath both armrests remain accessible from either side of the chair, while programmable positions help the dental team move consistently between consultation, treatment, and patient-exit positions.

Smooth, Controlled Movement

The Q5500 uses a soft-start/soft-stop electro-hydraulic system to create smooth transitions between chair positions. The system reduces abrupt starts and stops, helping patients remain relaxed while giving the clinician more controlled movement during positioning.

Programmable presets allow frequently used treatment positions to be stored and recalled. An automatic-return function helps bring the chair back to a patient-entry position, while a safety lockout helps prevent unintended chair movement.

• Soft-start/soft-stop electro-hydraulic movement
• Smooth transitions between upright and treatment positions
• Programmable chair-position presets
• Automatic-return function
• Safety lockout to help prevent unintended movement
• Electronic seat-rotation release

Intuitive Dual-Sided Controls

Membrane touchpads are positioned beneath both armrests, keeping chair adjustments within reach from the doctor or assistant side. The touchpads control seat height, backrest positioning, programmable presets, automatic return, safety lockout, and the electronic seat-swivel release.

By integrating the primary chair controls into both sides of the chair, the Q5500 reduces the need to reach across the patient or move away from the treatment area to make an adjustment.

• Membrane touchpads located beneath both armrests
• Seat-height and backrest controls
• Programmable preset controls
• Automatic-return control
• Safety lockout
• Electronic seat-swivel release

Clinical Access and Working Posture

The Q5500’s slim, contoured backrest allows the dental team to work closer to the patient with less obstruction around the oral cavity. Shortening the working distance can help reduce excessive reaching and support more comfortable positioning during longer procedures.

A dual-articulating headrest rotates forward and backward to support precise positioning for both the upper and lower arches. This allows the clinician to adjust the patient’s head and neck independently of the main backrest, reducing the need for repeated full-chair repositioning.

• Slim, contoured backrest for close operator access
• Dual-articulating headrest with push-button release
• Forward and backward headrest positioning
• Improved access to maxillary and mandibular arches
• Chair profile designed to reduce interference around the treatment area

Patient Comfort and Entry

The chair’s contoured seat and backrest support the patient throughout upright, reclined, and treatment positions. Its smooth hydraulic movement is particularly valuable for patients who may be anxious about sudden motion or uncomfortable with abrupt positional changes.

Rotating armrests open outward to simplify patient entry and exit. This more open approach can assist older patients, children, and patients with limited mobility while giving staff additional room to provide support.

• Ergonomically contoured seat and backrest
• Smooth movement designed to reduce sudden positional changes
• Armrests rotate outward up to 130 degrees
• Open entry path for assisted patient seating
• Multiple upholstery widths and cushioning styles

Upholstery Configurations

The Quolis Q5500 is available in four primary upholstery configurations. Practices can choose a narrow or wide back and select either seamless or plush upholstery depending on the desired balance of clinical access, cushioning, cleaning, and appearance.

• Seamless narrow upholstery
• Plush narrow upholstery
• Seamless wide upholstery
• Plush wide upholstery
• Available in a broad selection of Belmont upholstery colors

A narrow-back configuration prioritizes close doctor and assistant access, while the wide-back option provides broader patient support. Seamless upholstery offers a streamlined, easy-to-maintain surface, while plush upholstery adds cushioning for longer appointments.

Construction and Daily Use

The Q5500 uses a compensating cantilever lift and cast-aluminum base engineered for frequent clinical use. Belmont manufactures its hydraulic components in-house, allowing the chair’s movement, controls, and structural components to operate as an integrated system.

• Compensating cantilever lift mechanism
• Cast-aluminum base
• Belmont-manufactured hydraulic components
• Electronic seat-swivel lock
• Safety stop activated through the chair’s motion-protection system

Is the Quolis Q5500 Right for Your Practice?

The Q5500 is designed for practices that consider chair positioning and operator access central to the treatment-room workflow. Its dual-sided touchpads, programmable controls, smooth hydraulic movement, and expanded upholstery choices make it a strong option for high-use operatories, comprehensive dentistry, longer procedures, and premium practice environments.

Compared with more straightforward chair platforms, the Q5500 places greater emphasis on integrated controls, refined movement, configuration flexibility, and the experience of both the patient and clinical team.
