Description from Modernica

The Case Study Fiberglass Rolling Chair is the classic office chair of choice. Modernica updated the vintage 4-star aluminum rolling base, with a contract-approved five-star base. The new five-star base surpasses the original design with an added weight-adjustable, tilt-control feature, which locks your chosen position in place. Also added is a fun to use, gas-lift height adjustment lever, for superfast height adjustments. The height is adjustable up to six-inches and the chair is easily tilted forward or back. The base rotates smoothly 360-degrees. Suitable for any corporate or home office space, this base has a five-year normal-wear guarantee.
