TrueDelta Reviews the Seat Room and Comfort of the 2013 Lexus IS

2013 Lexus IS Seat Room and Comfort: Pros
YearComment
2014 Following the Germans' lead, many car makers have been fitting firmer and firmer seats. Cadillac might have once been known for seats you could sink deep into, but those in the ATS are the opposite, with too little give and contours that are far from form-fitting. No fear, Lexus hasn't done the same with the IS. Even the more heavily bolstered seats that are part of the F Sport package lack hard points, which helps them provide a slop-free fit for a wide range of body types. (Oddly, you'll find seats similar to these in some Chrysler people haulers.) Personally, I wouldn't mind a little firmer support, but then I also prefer a firm mattress. Notably, the lumbar support in the Lexus IS is only two-way and the spread of the side bolsters is not adjustable. For four-way lumbar support and adjustable side bolsters (plus somewhat firmer support) you need to step up to the larger Lexus GS. see full Lexus IS review
