Whether it's Winter, Summer, Spring or Fall -- strolling is a breeze with the Sonar Seasons Stroller by Baby Trend. This unique stroller can convert from a traditional backrest to a breathable, mesh backrest by rolling the seat back up. Once it is rolled up, the seat back can be used as a pillow or it can be stored behind the stroller seat. The Sonar Seasons has a large basket that has both front and rear access, as well as a parent tray and child tray with cup holders and storage.
