GLS-Class Car Seat Configuration Overview
The current-generation Mercedes GLS-Class offers seating for seven with its standard configuration, providing multiple options for child seat placement. Through rigorous testing with various car seat types, we've evaluated every potential installation scenario.
Seating Capacity Breakdown
- Second Row: Accommodates two car seats comfortably with dedicated Latch anchors
- Third Row: Fits two car seats with some installation challenges
- Total Capacity: Four car seats maximum (two in each row)
Detailed Latch System Analysis
Mercedes-Benz has equipped the GLS-Class with a comprehensive Latch system, though our testing revealed some practical challenges parents should anticipate.
Latch System Advantages
- Three easily accessible top tether anchors in second row
- Two additional top tether anchors in third row
- Clearly labeled anchors differentiate from cargo hooks
- Sturdy seat belt bases aid booster seat installation

Latch System Challenges
- Recessed lower anchors require extra effort to access
- Rigid connectors struggle with stiff leather cushions
- Third row anchors sit deep in seat bight
- Seat belt buckles sometimes obstruct anchor access
Car Seat Installation Performance
We tested three common car seat types across all seating positions to evaluate real-world usability for families.
Infant Seat Installation
The Graco SnugRide Classic Connect 30 installed effortlessly in the second row using the hook-style Latch connectors. However, front passenger legroom became compromised when properly positioned rear-facing.
Convertible Seat Performance
The Britax Marathon convertible seat presented more challenges, particularly with its rigid Latch connectors. While the forward-facing position worked acceptably in the third row, second-row installation required head restraint adjustment and patience with the deep-set anchors.
Booster Seat Evaluation
The Graco TurboBooster fit adequately but suffered from the GLS-Class's large, non-removable head restraints pushing the seat away from the seatback. This issue was most pronounced in the second row but still noticeable in the third row.

Family-Friendly Features Assessment
Beyond car seat accommodations, we evaluated other aspects that impact family usability.
Third-Row Accessibility
The power-folding second-row bench creates a generous entryway to the third row, earning top marks in this category. The one-touch operation buttons near the head restraints make this process effortless.
Passenger Comfort Considerations
With car seats installed, front passenger space becomes limited. A 5'6" adult had adequate legroom when compromising position, but taller passengers will find the arrangement uncomfortable for extended travel.
Cargo Space With Car Seats
The GLS-Class maintains respectable cargo capacity even with all seating positions occupied. The flat-folding third row and 60/40 split second row provide flexibility for strollers and family gear.
Car Seat Check Rating System
Our standardized evaluation criteria ensure consistent assessment across all vehicles we test.
GLS-Class Overall Rating: B-
The Mercedes-Benz GLS-Class earns a B- rating in our evaluation. While it offers premium materials and sophisticated styling, some practical child seat installation challenges prevent it from ranking among the top luxury three-row SUVs for family use.
Expert Installation Tips for GLS-Class Owners
Based on our testing experience, these professional recommendations can help overcome the Mercedes' installation challenges.
For Second-Row Installation
- Use seat belt installation if rigid Latch connectors prove problematic
- Raise head restraints before attempting installation
- Apply firm pressure to compress stiff leather cushions when accessing lower anchors
For Third-Row Installation
- Consider seat belt installation as primary method for forward-facing seats
- Use a flashlight to properly identify anchors in deep seat bight
- Remove third-row head restraints for booster seats when possible

General Recommendations
- Always check for proper seat tightness (less than 1" of movement)
- Remember the 65-pound Latch system weight limit (child + seat)
- Consult your car seat manual for vehicle-specific guidance

Top-Rated Alternatives
- Volvo XC90: Exceptional safety features and easier Latch access
- Audi Q7: More accommodating second-row configuration
- Lincoln Navigator: Superior space for rear-facing seats
- BMW X7: Comparable luxury with slightly better anchor placement
Final Verdict: Is the GLS-Class Right for Your Family?
The Mercedes-Benz GLS-Class delivers premium luxury and sophisticated styling but presents some practical compromises for families with young children. While certainly usable, the challenging Latch anchor access and space limitations with rear-facing seats may frustrate parents who frequently install and remove car seats.
For families with older children primarily using booster seats or those who don't frequently rearrange seating configurations, the GLS-Class offers sufficient accommodations. However, families with multiple car seats or who prioritize effortless installation may prefer competitors with more thoughtfully designed child safety systems.
Ultimately, we recommend testing your specific car seats in the GLS-Class before purchasing to ensure compatibility with your family's needs.
