Sturdy and very comfortable, plenty of padding, love how the armrests are made so I can fit under my desk and the seat is large enough for me to comfortably sit cross legged. The massage/heat function is fun but more of targeted vibrations to upper back, lumbar and things, rather than the other massagers you see with the moving balls, still fun though! Only thing is that the back could maybe be a bit higher (thinking of tall people).
