Phantom 3 Premium Gaming Chair | Optimus Prime Edition | L

The AndaSeat Phantom 3 Optimus Prime Edition combines an official Transformers Autobot design with the cushioned Phantom 3 platform. A deep black Premium PVC synthetic leather exterior, embroidered Optimus Prime artwork and the Transformers logo give it a bold character-led identity.

The L-size chair includes an 11 cm, 60 kg/m³ moulded foam seat, external lumbar and head pillows, adjustable armrest height, deep recline and rocking. The official character design changes the appearance, not the core Phantom 3 functions.

The Optimus Prime Phantom 3 is listed in L. AndaSeat's current Phantom 3 guidance recommends this size for people approximately 150 to 185 cm tall and under 100 kg.

• Seat: approximately 50 cm deep and 52 cm wide overall, including the side supports.
• Seat height: adjusts from approximately 45.5 to 55.5 cm.
• Backrest: approximately 84 cm high and 55 cm wide at the shoulders.

If you are close to the recommended limits, compare the chair dimensions with your body, desk height and available recline space before ordering. Use our gaming chair size guide.

Choose the Optimus Prime Phantom 3 if official Autobot artwork belongs at the centre of your gaming, streaming or creator setup.

The deep black exterior keeps the character design focused, while removable support pillows and straightforward adjustment make the chair useful for both play and desk-based work.

The Optimus Prime Phantom 3 uses the Phantom 3 support and adjustment system:

• Cushioning: 11 cm thick, 60 kg/m³ moulded foam creates a substantial seat base.
• Removable support: an external lumbar pillow and soft head pillow let you change the backrest feel.
• Armrests: padded armrests adjust in height to help align your forearms with the desk.
• Movement: a deep backrest recline and up to 15 degrees of rocking support different sitting positions.
• Foundation: a steel frame, BIFMA-tested tilt mechanism, SGS-certified Class 4 gas lift, reinforced nylon base and floor-protective castors support the chair.

The Optimus Prime Edition uses deep black Premium PVC synthetic leather with embroidered Optimus Prime artwork, the Transformers logo and Autobot association.

The smooth synthetic surface helps the character panels stay clearly defined. The edition-specific difference is the official character design, not a claimed functional upgrade.
