"My Bighorn has changed everything... I don't even give stairs a second thought anymore! Before there was so much planning ahead to avoid stairs in the errands I had to run and plans my husband and I made. And I can go to the beach whenever I want! Even if a friend asks last minute."

-Erika, Sarasota FL


"Most chairs have their limits as to what you can do with them...where you can go. Not the Bighorn. This thing goes anywhere and does anything." 

-Drew, Tacoma WA
