I like the support of the back of this seat. I wish it adjusted more by moving the backrest further back, but it is very supportive and assist me in wanted to ride my bike more often.
Great addition to my bike rebuild project, looks good, however if your bike is 26&#34; or more and for males (center bar) the back on the seat makes mounting and dismounting a real challenge.

Very heavy in weight. Nice quality. Back support  is adjustable will make for a very comfortable ride....very good buy. Thanks.
