To begin with, the 160 kg (352.74 lb) weight-limit is more than enough. While the Calypso is larger overall than many gaming chairs with a similar weight-limit, there are its contoured edges on both the backrest and seat even I found somewhat confining, and I weigh less than half the stated weight-limit. The remaining space between these raised edges is not enough for a large user, for neither the backrest nor seat. Maybe if the raised edges weren't as tall, more space would be available for use. The combination of a tall backrest and neck-support cushion secured in place with straps going through the cutouts had me ditch the neck-support cushion as it was in turn awkwardly positioned for my height. That having been said, it is dense enough.
The backrest is very stable, which makes it comfortable. As the base of the seat appears to be rather thin, one might suppose that more cushioning should have been used. However, having used the Calypso, cushion density is plenty fine. The cervical support cushion is large, covering most of the pelvis area, and filled with memory foam.
Occasionally, small creases in the embroidery will appear. The armrests keep the arms steady and prevent them from slipping off. You can adjust the armrests using the buttons, and unlike some more expensive chairs we have reviewed, these are not moved easily by accident. Two sets of casters are included in the package, which is a nice touch many users will appreciate. One is wider and quieter on softer surfaces.
