The Double Cab is slightly roomier than the other Tundra models. It offers an inch more front headroom and a fraction more front-seat hip and leg room.
The 60/40 split-bench cloth seats that are standard in most models are welcoming and supportive. Double Cabs come with bucket seats up front, rather than the split bench.
Climbing in is easy, though the two-wheel-drive model seems to sit higher off the ground than other two-wheel-drive pickups. The Tundra feels tall in the saddle, giving the driver a commanding view over shorter vehicles.
Accessory switches are concentrated in the center cluster for easy operation. The fake wood on the dash is dreadful, but the instruments are straightforward, with a big tachometer on all but base models. A center console with four nice, big cup holders; dual map pockets; and covered storage is shared with the Toyota Sequoia SUV. Its lid holds a pad for note-taking, but it felt flimsy when we tried to use it. Double sun visors with extenders are useful at sunrise and sunset.
Access Cabs add interior storage space and the ability to carry two more passengers. If those passengers are adults, however, the rear seat is a short-term affair. The Tundra does not have nearly as much space in the rear compartment of its extended cab as the other full-size pickups. And the rear seatback is vertical, forcing occupants to sit bolt upright, uncomfortable for traveling any farther than the neighborhood restaurant. A far better use for the extended cab is carrying dry cleaning, groceries, briefcases, outdoor gear, or anything else that should be shielded from the elements. Unfortunately, the rear seat takes up a fair amount of room. The seat bottom on the split bench can be flipped up, but the seat doesn't fold completely out of the way, nor can it be easily removed. Some of the domestic extended cabs offer much better versatility.
Double Cabs, on the other hand, provide genuinely useful space for adult passengers in the back seats. Its 37.5 inches of rear-seat legroom make for comfortable accommodations, though Tundra's back seat still doesn't have as much space as in the Nissan Titan, Ford F-150, Chevrolet Silverado or GMC Sierra. But Tundra's rear seatback reclines at an angle of 24 degrees, adding to comfort. Each rear seating position has a headrest and three-point safety belt. Rear-seat passengers also enjoy their own heating and air conditioning outlets, and optional audio and DVD entertainment systems. Tundra Double Cab also offers the segment's first vertical power-sliding rear window. At 750 square inches, the Double Cab's rear window offers more than four times the open area of the manual sliding rear windows in the Regular Cab and Access Cab models, making it easier to access the bed especially important with a canopy. When the Double Cab's 60/40 split rear seat isn't occupied, it folds and tumbles to provide lockable, weather-tight storage space inside the cab.
Safety features for all Tundra models include seatbelt pre-tensioners and force limiters, along with the required dual front airbags. The passenger-side airbag can be switched off with the key when babies or children occupy the front passenger seat. A tire-pressure monitor is now standard.
