Hi Alan,
I’m the owner of DeepSeat. Personally, I weigh about #240 and I’m 5’8″ and use a size 18 DeepSeat. People built like us are exactly who I build these seats for. We ship all over the world, so I can get a seat to you pretty much anywhere. You can reach me by phone at 877-777-8020 or email at tim@kartlift.com.
Thanks.
