We would like to thank Caseking for supplying the review sample.

Nitro Concepts made its appearance in 2015 and has since introduced plenty of gaming chairs that won't empty your pockets. The German design team behind Nitro Concepts claims to have realized that gaming chairs can be of good quality while offering the anticipated comfort and costing less than high-priced top-end models. User feedback is also taken into consideration before the team starts designing a new chair with one goal in mind: a modern gaming chair that will cover the needs of any gamer. In this review, we set out to see if true or just another marketing statement.

The S300 EX Series uses a bucket-seat design and features the basic ergonomics any gaming chair with a reasonable price of $299.99 (€269.90) would. The cold foam upholstery is covered in soft PU (Polyurethane) available in four different color combinations. If one prefers something else, there is the S300 line covered in fabric and available in four additional color options. The steel frame and class-4 gas lift allow for the S300 EX to support anyone with a weight of up to 135 kg (297.62 lb).
