Fitting five adults in the 2010 Toyota Matrix is a stretch; it just doesn't have enough shoulder space to fit three people across, but there's decent legroom and plenty of headroom. Edmunds verifies that the bench is actually an "adult-friendly backseat," and Cars.com reports that the "front sport seats and a three-person bench seat give the [2009 Toyota] Matrix room for up to five people."
The Toyota Corolla Matrix "makes good use of its tall design by furnishing generous headroom," according to ConsumerGuide, and the "tilt and telescopic steering column and driver-seat height adjuster are comfort-enhancing standard features." Edmunds agrees with that assessment of the new steering column, reporting "the driving position is vastly improved in the '09 model, with credit going to the new telescoping steering wheel and increased seat-track travel."
Fold either or both portions of the split rear seatback forward and you'll find generous space for stuff, but with the 60/40-split seatbacks up in place, there's not a lot of grocery space. MotherProof does say that the cargo space is "a decent, day-to-day size, and there are grocery hooks in the back," while ConsumerGuide points out that the "front passenger seat folds flat on all but the base model for cargo-carrying versatility." ConsumerGuide finds that the "interior storage consists of a small glovebox, center console, and door pockets." Edmunds states "there are 19.8 cubic feet of luggage capacity behind the rear seats and a seats-down volume of 61.5 cubes."
The look and feel of the materials used in the 2010 Toyota Matrix is a subject of some complaint. ConsumerGuide notes "all Matrix models look built to price" with a "notable lack of padded surfaces." They also say "few materials feel substantial, and the doors close with a tinny clang." Cars.com contends the wrap-around look and surface textures "look rich from any distance," the "gauges and stereo controls have first-rate quality," and "panel fit is generally excellent," but all these positives only serve to accent clunky climate control knobs and a ceiling that's "a vast canopy of mouse fur."
Overall, the Matrix has a good ride, with less of the pitchiness exhibited by the last-generation model; top XRS and AWD S models come with a fully independent rear suspension that may bring an even smoother ride without sacrificing handling. However, across the line, road noise can be an issue; a surprising amount of boominess can enter the cabin from rough pavement. ConsumerGuide reviewers report that the "2.4-liter engine is raspy while accelerating," and "wind rush and road noise rise markedly at highway speeds on all models." Cars.com also notes that "at highway speeds, road and wind noise are considerable."
