Obaby Zynergi 3Tec Pushchair in Red Includes Chasis & Seat Unit The 3Tec combines all the best in design and engineering whilst keeping all of the benefits of a convertible pushchair and now on three wheels. So what are the benefits of three wheels? Under the seating area is perhaps the most impressive suspension in the business meaning your baby or toddler will always get the smoothest of rides whatever the terrain. The adjustable handles offer lots of options depending on how you like to push and the front wheel swivels and locks for your chosen level of locomotion. The seat unit, carry cot and car seat all fit quickly and easily and can face both ways. The seat unit is suitable from 6 months up to 15kg or 3 years and is made of the same high standards. It has a three position recline and the angle of the backrest provides optimal support for your childs back and spine. There are also comfortably padded shoulder straps and a sturdy padded bumper bar for extra security.
