Installed DESERT DOES IT Seatjackers (with Multimount Panel... set was on sale) on driver's seat of my 2021 Tundra. Bottom line: I am very satisfied with the high quality of the parts, and the effect on driver seating position and comfort!
I was a little leery because I am six four (with 32 inseam... long torso), so every inch of headroom and legroom matters, even in a spacious vehicle like my Tundra.
After installing, positioning seat, driving, and tweaking seat position, I can say that...
* Yes, the seating position is significantly different in ways I find more comfortable. I feel like I am sitting IN the seat as opposed to ON the seat, if that makes sense.
* Headroom and legroom are fine... In fact, strangely better than before! I find I can pull the drivers seat 1 click closer to steering wheel and still be comfortable. That means more legroom for anyone seated behind the driver. Also, ease of getting in and out of the vehicle is the same or slightly improved. Honestly, I am not sure why! I realize some of my reaction is subjective but there is definitely a different and preferable new geometry to the driving position that was worth the price.
The only constructive criticism I would offer is that the installation instructions could be improved. Pictures would be very helpful. As a writer of technical documents, I would argue for step by step photos (with a few more clearer instructions) to help those installing for the first time. My case was a little easier because my Work Truck Package doesn't come from the factory with any pesky carpeting.
Based on these results, I purchased a 2nd Seatjacker set for passenger seat!
