Can this fit on the base of a Stokke Tripp Trapp high chair?

HI Mary Kate! Looking at the picture if Stokke Tripp Trapp, I don't think the Upseat will fit. -- The Upseat Team

Can you use this on a stool?

Hi Sarah, thank you for reaching out to us. The Upseat should not be used on a stool. (more information can be found in the manual. https://cdn.shopify.com/s/files/1/2509/9588/files/Upseat_Instruction_Manual.pdf?v=1611762360) It should be used on a chair with a backrest. If you have more questions, please keep it coming. We are happy to help. Jobie The Upseat Team 1-888-977-1129
