    The chair can suit anyone from 5'2'' all the way to 6'5'' comfortably. Typically preferred by people that like to feel secure and 'hugged' by the chair.

    The Grandmaster boasts 6 inches more sitting width, and more open wing pattern, and more cold molded foam. They are otherwise the same dimensions.. Grandmaster is more for people that like to sit cross-legged or have a broader frame.

    Yes. The chair has an adjustable 12 degree multi-tilt mechanism that can recline and lock you in place at that angle. Adjustable 4d arm rests to move depending on your sitting style or preferred game. Removable memory foam pillows you can adjust to any position you prefer. Color changing tips you can replace with other colors at your preference.

    The memory foam pillows combined with the option to adjust your arm rests, tilt and height create an optimized setup that can add hours of play time to your set.

    Two layers of foam on top of high grade PU leather creates the softest chair you've ever felt with a high quality of engineering.

      More Bang for your Buck!

      I have tested other gaming chairs and I have to say, so far since I received this chair, it has been the best. Pleasantly cushioned and easy to assemble. Love that it reclines flat. It sits at the right height for me to put my feet on the floor and I don't feel like my behind is going to swallow the seat. The arm wrests having multiple options is awesome. I do wish the arm wrests had just a bit more cushion. My desk is like an inch taller than the arm wrests in height and my elbows start aching. Otherwise, great chair!

      Love this chair

      The chair is very comfortable and the cutomization of overall chair features is amazing. Only issue i had was putting it together, but i had to do it by myself which made it difficult. So i do recommend having a 2nd pair of hands to help with just in case. Other wise fantastic chair.
