The Razer RZ38-03710100-R3G1 gaming chair combines premium materials and ergonomic design for extended sitting sessions. Upholstered with Alcantara on the seat base and backrest and trimmed with durable leatherette on the outer edges, it delivers a balance of soft touch and resilience. The chair features a 21" ultrawide seat base, a built-in lumbar arch, a dual-density cushioned backrest and a magnetic memory foam head cushion. Its mechanism supports reactive seat tilt and up to 152° recline, and the frame supports a maximum user weight of 136 kg.

Advantages

Alcantara upholstery provides a premium soft touch while leatherette edges improve durability. The dual-density backrest offers firmer support at the edges and softer cushioning in the centre for targeted back comfort. A built-in lumbar curve encourages neutral posture, and the ultrawide 21" seat with 110° extended shoulder arches helps distribute weight evenly for long sessions. The magnetic memory foam head cushion is adjustable and stays securely in place. The tilt mechanism automatically responds to weight and also allows manual adjustment up to 152° recline.

Suitable for

• PC and console gamers who sit for long sessions
• Users needing extra lumbar support and wider seat base
• People up to 136 kg seeking a sturdy, premium-feel chair
• Those who value adjustable head and recline positions

How to use

Adjust the magnetic memory foam head cushion to a comfortable height by attaching it to the backrest where it supports the base of your skull and neck. Sit with your hips as far back as possible to align with the built-in lumbar arch for neutral spinal support. Use the tilt mechanism to find a natural seating angle; the mechanism responds to body weight, and the recline dial permits precise adjustment up to 152°. Ensure the seat base is centered and your feet rest flat on the floor or on a footrest for optimal posture.

Usage recommendations

For prolonged comfort, periodically change sitting posture, take short breaks every 45–60 minutes, and adjust the lumbar support and head cushion to maintain a neutral spine. Clean Alcantara and leatherette surfaces according to manufacturer care instructions to preserve appearance and durability.
