My MX had a bargin basement seat but did have a tension adjustable spring suspension. I bought a TSC seat with single shock absorber and weight suspension, And bolted to the existing kubota suspension. A $99 investment. A great improvement. The seat height did increase about 5 inches which I like, better visibility. The tractor supply seat has its' own fore/aft adjustment. The weight adjustment limit, 260 lbs. Seat back is taller and has mid bolsters.
Cushions angle and recline position is adjustable but not w/ a knob. Must relocate bolts to alternating mount boles so seat isn't quickly modified for multiple operators. Weight adjustment though is quick, turn knob, weight graduations are marked w/ indicator.
