I could never get comfy in a mei tai. My best guess is that it is because I am super tall and it's just harder on shoulders and upper back for a taller person? And also, I could never stand the feeling of the waist strap digging into my soft middle section. I am good in a structured baby carrier and tend to wear the waist strap low, on my hips. And I can teach someone else to use a mei tai and they'll prefer it over a structured baby carrier, so it's all up to individual preference, and the baby carriers too; each brand is so very different and fit can't be generalized!
