Does it work for big butt/high butt people?

It depends on how big is but normally works.

let me get this straight -- i need the chair AND i need the cover? Whats the difference b/t sitting crosslegged, on top of a small cushion and this?

The cover is not necessary but we recommend to who want a little more cushioning. The difference b/t Curble Chair and a kneeling chair is that Curble Chair helps you to sit up straight by supporting your back while providing the comfort of your legs.

Where do find the size chart?

Please refer to the video. Curble Grand is W16.5 x D12.7 x H13.6 inch which is a suitable size for adults. We also have other smaller models for petite, teenagers, and kids.

Where can I purchase replacement cushions and stops? How much more cushion does the cover provide? Thank you.

We are working on the replacement cushion to launch it on Amazon within 2023. We highly recommend the cover because you can use Curble Chair more comfortably since it covers all the edges of the Curble Chair and provide good ventilation with air mesh material.
