Is this cushion worth it?

If your seat is firm or you get sore on long drives, the memory foam adds real relief for a modest price. If you mainly want cooling or heating, this is not the product for that.

Will it fit my car seat?

It is a universal-fit cushion sized for standard car and truck seats, so it should work in most vehicles. Very narrow bucket seats or seats with heavy side bolsters may fit less well.

Does it make the seat too high?

It adds noticeable height because of the 6.6 lb memory foam fill. In cars with low roofs or a already-high seating position, check headroom before buying.

Can I use it on an office chair?

Yes. The universal fit and flat base work on most desk and dining chairs as well as car seats.

Does it have straps to keep it in place?

No straps or non-slip base are listed. On leather or vinyl seats it may shift, so reposition it after getting in.

Seat cushions like this tend to dip during back-to-school and holiday sales and in late summer. Its latest best price is already near the low end of its recent range.
