Frequently Asked Questions:

How is this different from a $200 office chair?

Budget chairs use lower-quality materials, limited adjustability, and generic sizing that doesn't fit most bodies properly. The FORMA offers professional-grade construction, comprehensive adjustments, proper sizing options, and durability that lasts 10+ years vs. 1-2 years for budget chairs. The difference in comfort, support, and longevity justifies the investment.

Will this help my back pain?

Proper ergonomic seating is essential for preventing and reducing back pain. The FORMA's adjustable lumbar support, seat depth adjustment, and proper sizing ensure your spine maintains its natural alignment, reducing the muscle strain and disc pressure that cause pain. However, consult your healthcare provider for medical advice about existing conditions.

How do I know which size to choose?

Size selection is based primarily on your height. Small for 5'0"-5'6", Medium for 5'6"-6'0", Large for 6'0"-6'6". If you're between sizes or have questions, our ergonomic specialists can help you choose based on your specific measurements and needs.

Is assembly difficult?

Assembly is straightforward and takes 30-45 minutes with the included tools and instructions. Most users can complete it themselves. Professional assembly services are available if preferred.

What's the warranty?

The FORMA includes Sitmatic's manufacturer warranty covering defects in materials and workmanship. Contact us for specific warranty details and coverage information.

Can I try it before buying?

While we don't offer in-store trials, our return policy allows you to experience the chair in your own workspace. We recommend giving yourself 1-2 weeks to adjust to proper ergonomic seating, as there's often an adaptation period when transitioning from poor to proper support.
