About this item

  • 【LUMBAR SUPPORT THAT MOVES WITH YOU】 Your posture never stays the same—and your lumbar support shouldn't either. The B300 PRO ergonomic office chair features a spring-assisted 4-way lumbar system with independent height adjustment, forward glide, and adaptive flex that follows every movement of your lower back. Whether you're tackling deep-focus projects, switching between virtual meetings, or stretching back to relax, it delivers continuous support that helps reduce pressure and keeps your spine comfortably aligned throughout the day.
  • 【A BACKREST BUILT AROUND YOU】 A truly ergonomic chair adapts to your body—not the other way around. The independently height-adjustable backrest lets users of different heights position lumbar support exactly where it's needed, encouraging natural posture and consistent full-back contact. From productive work sessions to moments of relaxation, every adjustment creates balanced support that feels customized, effortless, and comfortable.
  • 【SIT DEEPER. STRETCH FARTHER.】 Long hours deserve more than just a comfortable seat—they deserve room to fully unwind. The adjustable seat depth provides personalized thigh support for different leg lengths, while the retractable footrest lets you elevate your legs and relieve pressure whenever it's time to recharge. Whether you're working, reading, gaming, or taking a well-earned break, the breathable mesh seat keeps you cool, supported, and comfortable from start to finish.
  • 【RECLINE INTO TOTAL RELAXATION】 Switching from work mode to relaxation should feel effortless. The smart weight-sensing recline automatically adapts to your body weight, delivering smooth, balanced resistance without manual adjustments. Pair it with the retractable footrest to stretch out, reduce leg fatigue, and enjoy a more weightless reclining experience—whether you're taking a quick break, watching a movie, or simply resetting between tasks.
  • 【FULL-BODY SUPPORT FROM HEAD TO TOE】 Comfort isn't limited to your back—it's a full-body experience. The oversized 3D headrest supports your neck through long work sessions and relaxed reclining, while the 6D armrests adjust in every direction to keep your shoulders and arms comfortably aligned. Complete the experience with the retractable footrest, giving your legs the support they need so your entire body can relax in perfect balance.
  • 【ENGINEERED TO LAST ＆ SUPPORTED WITH CONFIDENCE】 Built with premium-quality materials and rigorously tested to meet BIFMA, SGS, and TÜV standards, the B300 PRO is designed for years of dependable ergonomic comfort. Every chair is backed by a 3-year warranty and a 30-day hassle-free return policy, while our dedicated customer support team responds within 24 hours to deliver fast, reliable assistance whenever you need it. Invest with confidence—and enjoy lasting comfort every day.

How can I check whether a product will fit my workspace?

Please review the dimensions, weight capacity, mounting requirements, and available clearance listed on the product page. For desks, chairs, cabinets, and mounted accessories, we recommend measuring your room, doorway, desk surface, and installation area before ordering.

How do I know whether an electronic accessory is compatible with my device?

Check the product page for supported device models, port types, operating systems, voltage, plug type, monitor size, weight limits, or printer compatibility. Contact us before purchasing if you are uncertain about compatibility.

Do office furniture products require assembly?

Many desks, chairs, cabinets, stands, and shelving products require some assembly. Assembly requirements and included hardware vary by product, so please review the individual product description and instructions before purchase and use.

How much does shipping cost?

Why did only part of my order arrive?

Products may be stored in different warehouses or shipped in multiple boxes. As a result, items and furniture components may arrive separately with different tracking numbers. Please review all shipping confirmation emails before reporting an incomplete delivery.

Can I change or cancel my order?

Please contact us as soon as possible after placing your order. We will make a reasonable effort to update or cancel an order that has not entered processing or shipment, but changes and cancellations cannot be guaranteed once fulfillment has begun.

What is your return policy?

Eligible products may generally be returned within 30 calendar days of delivery, subject to our Return & Refund Policy. Items should be unused, unassembled, uninstalled, and returned with their original packaging, hardware, manuals, and accessories. Contact us for authorization before sending a return.

What should I do if my product arrives damaged, defective, or incomplete?
