Forest 3900 Hydraulic Chair

The Forest 3900 Hydraulic Chair pairs premium patient comfort with the durable construction, flexible positioning, and extensive finish options Forest Dental is known for. It is designed for practices that want a highly configurable treatment chair with a thin-back profile, supportive upholstery, programmable positioning, and a smooth hydraulic cantilever system.

A wide back supports the patient at the elbows and tapers toward the shoulders to help the clinician work closer to the oral cavity. The double-articulating headrest, full recline, swing-down armrests, and right- or left-side access support efficient positioning across routine and longer procedures. Standard Ultraleather® upholstery gives the chair a soft, professional finish while standing up to daily clinical use.

Forest 3900 Chair Features

• Thin back with full lumbar support: Balances patient support with closer clinician access around the head of the chair.
• Double-articulating headrest: Adjusts for a range of patient heights and treatment positions and can be reversed for supported wheelchair positioning.
• Plush Ultraleather upholstery: Provides a soft, durable patient surface in a wide selection of standard colors.
• Smooth hydraulic cantilever: Delivers quiet, stable movement with adjustable base and back positioning.
• Four programmable positions: Stores commonly used treatment and patient-exit positions while retaining manual base and back control.
• Flexible control placement: Controls can be configured at the chair, delivery unit, or foot control to match the operatory workflow.
• Swing-down locking armrests: Provide easier patient entry and exit without swinging outward into the treatment room.
• 30-degree swivel with lock: Adds positioning flexibility while allowing the chair to be secured for treatment.

Comfort and Customization

The 3900 can be configured with wide-back, narrow-back, or narrow-back-with-slings upholstery profiles, depending on the needs of the practice. Plush upholstery is a strong everyday choice, while available seamless and Memory Comfort options give practices additional ways to balance cleanability and long-procedure comfort.

Forest’s Designer Friendly® options extend beyond upholstery. Available selections may include dual-color upholstery, contrast stitching, multiple powder-coat finishes, and coordinated delivery-equipment finishes. Optional neck and knee pillows, a pediatric booster, and a Soft Touch back-massage system can further tailor the patient experience. The massage option is not compatible with the Memory Comfort upholstery configuration.
