A good stroller seat reclines fully, and has adequate width and seat-back height, and is not situated too high off the ground

• Even though most do not recline to a truly flat position, pay attention to the degree of recline given your child's age. Babies should lie flat, and toddlers should sit upright. A reclining seat is much safer for babies and also allows them to sleep more easily

• Stroller Seat height, width, and depth are critical for baby's comfort. It's an issue that most parents 'clue into' only after their stroller purchase. In general, you'll find that most seat-backs are around 20" high, seat-bottoms around 10" long, and knee-to-foot length around 11" - 12"

• Make sure that the stroller you end up buying does not have stroller seat measurements that are significantly smaller than those mentioned. If you neglect this, you could end up with a stroller that won't fit your child or one that your child out-grows very quickly

• Height off the ground affects stability when running. The lower the child sits, the more stable the stroller - but you don't want your child riding too low! For example the attachable back seat of the Phil & Ted e3 Explorer rides very low to the ground when a 25lb child is travelling in the rear. Seat issues must be taken into consideration when you are test-driving the different brands and models.
  

The 5 Point Harness

• A harness is a series of straps that holds the child in the stroller. (Like a fancy seat-belt). The 5-point harness is generally accepted as the safest way to keep your child secure. 5Pt Harness 150 It has (surprise, surprise) 5 straps: two at the shoulders, two at the hips, and one at the crotch

• Look for a harness that is easy for you to lock and unlock, and can be operated with one hand. (It should be tamper proof and difficult for the toddler to unlock!)

• Make sure that straps are well padded and that the adjustable sliders are easy to operate - and easy to operate with one hand. When testing, ensure that the harness is sufficiently adjustable to hold any size toddler snugly.
  

• For those in cold climates, bulky sweaters and snow suits will alter how snugly the child fits. Once again, make sure that the straps can extend far enough to accomodate this.
