I just got a 2022 GMC SIERRA Limited SLT with 63000 miles, all the options, heated/cooled/vibrating. Replacing my 2009 sierra denali with 225000 miles and I can't believe how uncomfortable the drivers seat is. GM must have skipped out on the padding to dave a buck. After reading through this post I feel like this is a widespread problem that GM won't address. Has anyone reached out to some aftermarket companies to make a replacement cushion that is bearable to sit on? I've gotten several replacement covers and cushions from www.theseatshop.com and have been very happy with thier quality. Maybe if enough of us request it they will make something for us. Thoughts? I'm willing to make some calls to different vendors.
