TrueDelta Reviews the Seat Room and Comfort of the 2012 Mercedes-Benz GLK

2012 Mercedes-Benz GLK Seat Room and Comfort: Cons
YearComment
2011 Expect the GLK to grow when it is next fully redesigned. A smaller MLK is on the way to battle the upcoming Audi Q3 and just-arrived BMW X1. For 2013, the GLK's body structure remains essentially the same, so rear seat knee room remains just sufficient for a man of average height sitting behind another such man. (Headroom, on the other hand, is abundant.) Among competitors, only the Infiniti EX37 has a tighter rear seat. The Audi, BMW, and Volvo all offer knees another inch or three. Seat comfort is debatable. To my bottom, the GLK's seats feel overly firm. Cargo space is similarly short of the segment average. The GLK's 54.7 cubic feet isn't far behind the Audi's 57.3 but well below the X3's 63.3. That truncated tail has a downside beyond aesthetics. But do these shortcomings really matter? For most people nearly all of the time, there's enough space. see full Mercedes-Benz GLK review

I have a problem with headroom. So many cars give me less than a half inch from my scalp to the frame on the sunroof. That hurts over bumps, not to mention what my hair looks like when I get out. GLK has over an inch of space for me. see full Mercedes-Benz GLK review

We are a couple with no kids and we rarely have visitors so the cramped rear seating is not a problem. Someone with teenage kids will want to seriously reconsider before getting a GLK. I know my Mom would not appreciate the ingress/egress ease as she has some limited mobility. see full Mercedes-Benz GLK review

If you are 6' plus like me, you will have to adjust the front seat forward if you want passengers to ride with you unless they are quite small. But this is a perfect city hauler for a single or couple. see full Mercedes-Benz GLK review

3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review
