2026 Mercedes-Benz GLS Seating and Second-Row Features for Chicagoland Families

If you’re asking what Mercedes-Benz has with three rows and real passenger comfort, the 2026 Mercedes-Benz GLS is the full-size SUV to start with. This guide covers 2026 Mercedes-Benz GLS seating and second-row features in plain terms, so you know what to look for before you visit. When you’re ready to compare, you can browse new GLS SUVs from our Hoffman Estates showroom.

2026 Mercedes-Benz GLS Seating Configurations: Seven-Passenger or Six-Passenger Captain’s Chairs

The 2026 GLS comes as a seven-passenger cabin, with a six-passenger cabin as an option. In the middle row you’ll find either a power bench with room for three or individual captain’s chairs with a walk-through to the third row.

Standard and Available Seating Layouts

The GLS 450 4MATIC®, GLS 580 4MATIC®, and AMG® GLS 63 all offer a 7-seat cabin as standard and a 6-seat cabin as optional. The table also shows where second-row heating and climate zones differ by model.

Which Layout Fits Your Family

Start with who rides in the middle row on a normal week. Here’s the part that surprises people: on the GLS 450 and GLS 580, the captain’s chairs are a no-cost option. You’re not paying for the privilege of six seats instead of seven, so the decision is purely about how your family uses the space.

• The 40/20/40-split power bench seats three across, which suits families who fill every seat regularly and want that middle position for a car seat.

• Captain’s chairs give two passengers their own seats with individual armrests, and leave a permanent walk-through to the third row.

• Six passengers instead of seven trades one seat for easier movement between rows.

Bring your usual passengers and any child seats when you visit. Capacity rarely settles it by itself.

Second-Row Features: Captain’s Chairs, Comfort and Charging

The second row is a full passenger space. Mercedes-Benz offers power adjustment and reclining, along with several comfort options. Keep the layout separate from the comfort equipment in your mind, because they are chosen differently.

Power-Adjustable Captain’s Chairs and Available Bench Seat

Second-row seats power-adjust and recline on every GLS, bench or captain’s chairs. That does two jobs: it settles a passenger comfortably, and it balances space between the second and third rows. Slide the middle row forward a few inches and a teenager in the back stops complaining. Slide it back and the second row becomes the best seat in the vehicle.

Available Heating, Ventilation and Massage for Rear Passengers

The GLS 450 offers heated second-row seats as an option; the GLS 580 and AMG® GLS 63 include them as standard. Beyond heating, the real upgrade is the Executive Rear Seat Package Plus, which bundles second-row wireless charging, a second-row MBUX tablet, and heated, ventilated, multicontour, and massaging second-row seats into a single option. If rear-seat comfort matters to your household, that package is where to look rather than chasing features individually.

Rear Climate Controls, Sunshades and Charging Ports

The GLS 450 has 4-zone automatic climate control as standard, with 5-zone optional. The GLS 580 and AMG® GLS 63 come with 5-zone. That system has separate left and right zones in the first and second rows, plus a fifth zone for the third row. One button synchronizes it as a single cabin zone.

Power second-row sunshades are optional across the lineup, running around $580. Front-cabin wireless charging with NFC pairing is standard; second-row wireless charging arrives with the Executive Rear Seat Package Plus. Third-row passengers get dual USB-C ports along with side armrests, cup holders, and storage trays, so the back row isn’t an afterthought on charging or storage.

Third-Row Access and Power-Folding Seats

The seats are only half of it; getting people into the back counts too. Captain’s chairs leave a walk-through, and the second-row seats adjust and recline to ease third-row access. Power-folding then turns the same space into cargo room.

Easy-Entry Function for Kids and Adults

EASY-ENTRY power second-row seating comes standard, tilting and sliding the second row forward at the press of a button rather than asking anyone to wrestle a lever. With captain’s chairs you also get a permanent center aisle, so nobody has to move a seat at all.

That said, an installed child seat changes the math, and door-opening space in a tight garage or a school pickup lane matters as much as the mechanism. Test access twice when you’re here, once the way a child would climb in and once as an adult, and do it with your car seat installed if you use one.

Power-Folding Controls and Cargo Flexibility

Power-folding 50/50-split third-row seats are standard on all three models. You move between a full passenger setup and a larger cargo area without folding seatbacks by hand. Pack the GLS with your own gear and see how the folded third row handles it.

Third-Row Comfort: Legroom, Climate and Visibility for Passengers

Third-row legroom measures 34.6 inches, which is generous for a full-size luxury SUV and enough for an adult on a real trip rather than a token third row. Because the second-row seats power-adjust and recline, you can also shift space between rows depending on who’s riding where, so that figure is a starting point rather than a ceiling.

Climate is the clearer advantage. With the 5-zone system the third row gets its own zone, and ceiling-integrated air outlets push air where back-row passengers actually sit rather than around their ankles. The whole cabin can also sync to a single zone at the touch of a button when nobody wants to negotiate.

How the 2026 GLS Seating Fits Chicagoland Family Life

Chicagoland families ask a lot of one vehicle. Here is how the layouts play out in common situations, framed as use cases and not measured results.

School Runs, Carpools and Errands

For carpools, the power bench makes the most of every seat. Captain’s chairs make moving between rows easier when kids hop in and out at drop-off. For errands around Schaumburg and nearby suburbs, the 50/50-split third row lets you mix seating and gear. Test a typical week’s load before deciding.

Airport Trips and Drives into Chicago

An O’Hare run is a trade-off between using every seat and leaving room for luggage. Load your usual passengers and bags before you decide. For drives into Chicago with repeated stops, easy third-row access and flexible cargo space help when passengers change from one leg to the next. Every household weighs these things differently.

Winter Comfort and Midwest Road Trips Around Illinois

Illinois winters make rear-seat heat a real consideration, not a luxury. Heated second-row seats are standard on the GLS 580 and optional on the GLS 450, and the third row offers optional seat heating too, which matters on a January morning when the back row takes longest to warm. The 5-zone system lets each part of the cabin settle at its own temperature, so nobody’s fighting over the thermostat between Hoffman Estates and Rockford.
