actually i have found them better then my last few cars. made a few long drives last summer and did not find myself constantly moving around and shifting like in other cars. but i have heard/read the opposite so depends on body type

 

 

i find them less comfortable than 14/18 way seats found in the Porsche 991 cars......they are simply more stiff and have less padding......are they uncomfortable to me (5'10 athletic)? no. are they as comfortable as the standard c63 seats? i personally don't think so. i love their look though!

 

I found them uncomfortable on a short journey. I test drove one with the performance seats and immediately knew that I'd prefer the regular ones.

 

 

I've got a new C63S and I've had it just over a week. So far I've done just over 400 miles in it.

I'm finding the performance seats really uncomfortable. My back, hips and backside is in pain with these seats. I'm about 18 stone (250 pounds) and after reading these posts, could this be the issue? Being over-weight?
Has anyone got any tips to improve the comfort of performance seats?

BTW, In the UK if you buy a C63S you get performance seats, there is no other choice.

Thanks.

 

I was 260lbs and I don't feel like I was ever that uncomfortable. I would feel pressure from the side bolsters because I was a little wider than the side bolsters would allow for but I don't feel like I ever complained about pain. With that being said, I'm at 235 now and I will admit it is better. I fit in the seat more comfortably. I know it seems silly but double check that both sets of bolsters are in the full relaxed position. I got my car back from the valet one time and the seat had clearly been moved. I hit the memory setting and off I went. About 30 mins into the drive I kept moving around saying something isn't right with this seat. I hit the memory setting again and again with no changes. Started messing with lumbar and bolster settings and sure enough, they weren't in the full relaxed position. The memory doesn't save those settings. My E90 M3 was the same way. So I would check that and I would also try different lumbar settings. Sometimes I feel like having too much lumbar in pushes you out of the seat and makes you sit awkwardly causing other problems. Hope that helps.

 

C63 is a "luxury" coupe but I don't think it's meant to be very comfortable. I have the performance seat and I find it quite acceptable. Too comfortable and I'll fall asleep like in my wife's SUV. Basically it's like complaining to the dealer about jerky shifts. Sure, they will fix the problem, by detuning the crap out of it. C63 are meant to feel "sporty".

 

 

I don't find my Performance Seats uncomfortable at all, rather the opposite. Way better than the ones I had in my Audi S5 and my CLA 45 AMG. I'm 193cm/6ft 3” and about 90kgs/200lbs.

 

 

Maybe father time is catching up with you now?

 

 

I have a friend who flips cars. He bought a MY16 sedan with performance seats. He's kind of on the heavier side and he told me after he drove the car for an hour his back hurt so bad he had to take Advil. I assumed it was because he just didn't fit, but I sat in the car to check it out sometime later and noticed the bolstering was set to the tightest, most inward position. I showed him how to adjust the bolsters using the switches on the side of the seat and he said it got 10x as comfortable, and had no problems after that. I think Mercedes should put those controls somewhere more visible with more context for those who are unfamiliar with the car.

 

 

I do agree they are a bit hard regardless...

 

same here.... 20 minutes and let me out of this test drive.

 

Despite my preconceptions, I find them to be completely comfortable, even on longer drives (3 hour), and I am 6'1" 245 lbs.
I always viewed the car as a performance vehicle, rather than a luxury one, so that perception may color my opinion.

The seats are definitely not cushy, with endless adjustment, but i've never felt discomfort in them and I like the way the bolsters hold you in position when cornering.

 

it's an odd one, on the gla 45 i had, sometimes i messed with the lumbar support and, i just couldnt get comfortable at all and on longer journeys (1 hours +) i would feel a bit iffy with definite back ache. Seems like the problems started when i becan messing with the rear back support. Had AMGs with these sorts of seats now for 18 months. That said, i reckon i'm used to the seats totally. The new car (estate c63s) has given me no problems in terms of discomfort at all no matter how long the journey except the extendable thigh support area which is not the most comfortable. I'm 5'11 and athletic (160ish LB) and dont have much padding on my rear end so tend to get uncomfortable easily. Spent a few hours at an AMG course in similar seats just today and driving like i stole the car, drifting etc. Not one second of discomfort. i suppose my focus was elsewhere (not crashing into a barrier).But on longer journeys i do think these seats are not ideal sometimes and i've thought about getting a thin layer of padding to put onto the back and bottom of the seat which i am sure will do the trick.

Apparently, the s version can be specced to have the standard amg sports seats rather than the performance ones.

 

Justhaving taken delivery of a 2018 S sedan I can tell you " the standard AMG sports seats" are what is standard in the S car, at least here in the USA. The performance seats are an extra cost option.

 

 

 

 

Quite the opposite for me. I'm 5' 7'' and feel they are the most comfortable, aggressively bolstered seats I've sat in... I love them. I was fully expecting to be in pain during long trips, but I've done 5+ hour trips with no problems. My wife finds them extremely comfortable as well, and she has lower back issues.

I used to daily my old B5 S4 with Status Racing Ring Bucket Seats, and those things were insanely bolstered. Carbon fiber shell (weighed around 8-9lbs for the whole leather seat), with memory foam padding. Now THOSE things were uncomfortable! But looked freakin' great. There was no way you could fit in them with a waist larger than a 32''.
