Adding to them is the new S300 series from Nitro Concepts. Available in a variety of color options, Nitro Concepts says the S300 is the "best chair we've ever built." >From Nitro Concepts' description (we haven't saddled up in one of these ourselves), the S300 uses high-quality cloth on top of breathable cold foam. The chairs are extra open in design, with the main body measuring 57cm wide and 87cm high. A class 4 gas lift adjusts the seat between 48cm and 61cm.
