Introducing the Grow & Go, Safety 1st’s new 3-in-1 fresh to the market. The Grow & Go can accommodate children rear-facing, forward-facing, and as a booster. We’ve tried it here in all modes and given it our usual thorough treatment!

Safety 1st’s manual, and matching colour coded labeling on the seat, is an excellent first glimpse at what the seat can do. Very clear, very easy to follow along, and a super way to get an overview of the seat and understand how it might work for your family.

Seat Specs:
- Rear facing: 5-40lbs AND between 19-40″ tall AND at least 1″ of head rest above the head
- Forward facing: 22-65lbs AND between 29-49″ AND harness coming from at or above the shoulders AND at least two years old
- Booster: 40-100lbs AND 43-52″ AND at least four years old
- Lowest harness height on infant harness routing (with required body padding): approximately 5.25″
- Lowest harness height on no-rethread harness routing (with optional body padding): approximately 9.5″
- Highest harness height (without optional body padding): approximately 17″
- Maximum seated height while rear-facing: approximately 26″ (chances are the 40″ standing height limit will be reached first however)
- Three crotch buckle positions: approximately 4.75″, 6″, 7.25″
- Highest booster belt guide position: approximately 18.5″
- Ten year expiry period
- Available at Babies R Us for $279.99
Seat features:

- Dual cup holders
- Sleek styling with a grey herringbone fabric
- Lots of leg room rear facing
- Easy to convert between modes of use
- More – see photos below!
Really handy harness holders so you don’t have to dig the buckles out from under your child. Two ways to use them: hook the harness over top (we found this easiest) or pop the buckle tongue into the slot made especially for it.


Colour coded, easy to read labeling on the side of the seat. Blue for rear-facing, red for forward-facing and booster (there is some overlap in instructions with these two modes hence the doubling up of colour). One handed, super-smooth recline adjustment for rear- and forward-facing, and large visible indicator of position.

Easily removable soft goods and seat cover (not an iPod plug-in as I thought when I first glanced at it). The fabric is nice and feels like it would not pill or snag. The padding provides ample body and head support. Most is optional so customize fit to your liking. Harness pads are a new design and are longer on the underside and shorter on the outside. They were easy to position, and removed quickly with velcro.

Rear Facing:
Great news – this seat will fit from birth, and quite easily. The harness tightens fully, the harness is slightly below the doll’s shoulders, and the fit is good. Setting the seat up for newborn use requires re-routing of the harness to both shorten and lower it. Safety 1st has found an ingenious way to make the seat actually fit a newborn through a school-age child. Pay careful attention to the steps in the manual to set the seat up for newborn use (and the reverse when ready to move to the no-rethread “Quick-Fit” harness system). It’s not difficult nor time consuming, but does require manual reading and following the steps as indicated.
Modeling the seat we have a newborn doll, a ten month old, a 25 month old, and just turned 3 year old (the 3 year old in the green sweater is 38″ tall for reference).
Kids liked the dual cup holders, ample leg room, and squishy padding. Parents liked the harness covers, attractive fabric, nicely positioned headwings that provide head support but don’t block the view, and low profile of the seat shell itself that enabled easier loading. One parent noticed that the harness release button is discreetly tucked away to make it just a little bit harder for those Houdini kids to wriggle out.


Forward Facing:
The features that appealed rear-facing also appeal forward! Dual cup holders, easy to adjust no-rethread harness, and squishy comfortable fabric. The crotch buckle pad is optional, as is the body padding and extra head pad. All are easily removable. This seat can not be used forward facing until age two, and should fit most kids in harness mode through at least age five. Shown here is aged 2.5-5, approximately 30lbs through 42lbs, all of whom declared it comfy. Of course all kids come in different sizes and proportions so shorter torsoed kids will fit in harness mode for longer (blond girl in summer attire has always been long in the torso for example).

Booster Mode:
The Grow & Go may be used as a booster once a child reaches the minimums for this mode but we’d recommend you keep kids harnessed as long as they fit, and then ensure they’re mature enough for a booster. If that describes your child, then carry on! Belt fit is quite good on the kids we tried it in but there isn’t much time for booster use (by torso height) beyond when it’s outgrown in harness mode.
At 5.5, 46lbs, and 45″ tall (pink sweater) and 7.75, 55lbs, and 50″ (blue tartan) these two both fit in booster mode. The older child is just squeaking in (her shoulder is grazing the head wing). Lap belt fit on both is excellent. Use of the upper shoulder belt guide is optional if needed to properly position the shoulder belt centered on the shoulder, and on the buckle side both lap and shoulder belt should tuck under the harness storage tab as shown above. The booster weight limit of 100lbs is hugely overstated in our opinion – as you can see height is much more of a limiting factor than weight.

UAS and tether are not to be used while the seat is in booster mode – follow storage instructions, and teach your child to rebuckle the empty booster when it’s not occupied so it doesn’t become a projectile in a crash. It is a very simple process, however, to switch between harness and booster mode. No unthreading of the harness necessary – tuck it behind the red plate as shown in the photo. Then a quick removal of the crotch buckle, tuck the tail of the harness adjuster under the seat pad, and remove all padding and accessories. Our tip: stow it all together in a labeled Ziploc bag so you don’t forget what seat it belongs to.

Fit to Vehicle:
The Grow & Go installed quite nicely in our test vehicles. Two important aspects to note for rear-facing however: the red bracket shown below, and the rear facing level line. Both of these elements are shown in the following installation pictures but they are important enough to highlight here so they aren’t missed later on.

Our representative small sedan is a 2012 Honda Civic. A centre installation allows a decent amount of leg room up front – enough for an average driver – but those requiring the seat all the way back are going to want to use an outboard position (more on that shortly). Installing centre means a seat belt must be used (most vehicles do not allow the use of UAS in the centre, check your vehicle manual to know if yours does).

The single recline line rear-facing means that this is how it will fit for the entire time spent rear facing. Make sure this setup suits your family; there will be ample room in medium-large vehicle interiors. If your vehicle seat is too sloped to achieve the needed recline a small tightly rolled towel or chunk of foam pool noodle cut to length can be placed at the seat bight to further recline the Grow & Go. The base of this seat is nice and slim, and at 9″ wide should fit easily between the plastic hinges present in many vehicle interiors.
Note the proper belt routing here relative to the red brackets. Slide only the lap portion through – it’s easily accessible and the webbing slides freely to tighten, but must be routed through the red guides for proper installation.

For comparison here is an outboard installation with UAS. Driver’s seat is all the way back, with dazzling pink running tights showing off the resulting front passenger room for a leggy 5’8″ person when the seat is properly installed behind it. It is important to note that the UAS strap (when used) also routes through the red guides on both sides.

Forward facing installation is very straightforward – quick and easy whether you are using UAS or seat belt. The adjustable head rest sits slightly forward of the seat shell and will limit interference with forward-leaning head restraints in vehicles. Always check your vehicle owner’s manual for proper tether routing (under, over, or around a vehicle head restraint). The belt path is high enough that installation should be simple in most vehicles.

Overall Impressions:
For families wanting to buy one seat for use from birth through to the high back booster stage this is a very attractive option. Those of you with medium-large vehicle interiors should have no trouble attaining the required recline rear-facing through that use of the seat. High five to Safety 1st for blazing the trail to require a minimum age of two to use the seat forward-facing. This seat should reasonably last for most kids through age 6 if not longer, depending on proportions. If you have one of those immensely long torsoed children — something you won’t obviously know if you are shopping while still pregnant! — you can always cross that bridge when you come to it. At a minimum you will need a backless booster to last your child through age 10-12 when their boostering days are over and they pass the Five Step Test for seat belt fit.
The finishing is nice, the features are easy to use and clearly labeled, and kids and parents alike find it comfortable and user-friendly. It has to be rather difficult to design a seat that truly will fit a newborn AND a 6 year old well – but Safety 1st has done it.

UPDATE Nov 2022: The Dimensions was discontinued some time ago, but this favourite seat lives on in its Contender version, which is now sometimes also called the Graco Admiral.













Updated March 2019. Note for all photos: Dorel is updating the angle at which a rear-facing seat may be installed. Newer versions of the seat may not be permitted to go so upright. Read your manual carefully, and follow the one that came with your seat.


The NEXT has a line on the side that must be parallel to the ground for children who can not sit up unassisted – this is to protect the child’s airway and enables them to keep their heads properly tilted back.













Properly introducing the Evenflo SecureKid! It has had a place on our 









It’s not very often that a new seat blows me away…but that honour goes to to 










Seat belt installations and UAS were both successful. Pro tip: most seats have some way of exposing the belt path. Doing so will make installing infinitely easier. On the Defender this can be accomplished by separating the cover at the lower outside corner and peeling it back. Tighten the belt from the inside of the seat – this works for the UAS strap as well as the belt. Clever body positioning means you can get maximum leverage without requiring herculean strength to tighten.






Updated 2019. The Monterey as described in this article has been discontinued, which makes us super sad because we loved it so very much.













The Monterey also worked exceptionally well in most seating positions and vehicles that we tried. It does have UAS hooks to latch the booster into the vehicle with an up-front adjustment mechanism to tighten and loosen each connector. This does not provide any extra safety to the booster rider, but does mean that the booster seat isn’t a projectile when not in use, and is a convenience feature that we find, well, convenient! Use of UAS is an optional feature, and if you don’t have UAS in the position you use the booster in we always recommend buckling the booster in when not in use.
Sometimes with high-back boosters the shoulder belt won’t always retract properly through the belt guide. This is not ideal as the belt won’t be in a good position to keep a child restrained properly if, for instance, the child has leaned forward (hopefully while the car is not in motion!) or if you have had to brake suddenly. Compared to previous versions of the Diono and Sunshine Kids Monterey this revamped Diono Monterey has a redesigned belt guide that tends to be very friendly with most shoulder belts. We found it worked very well in most of the vehicles/seating positions that we tried, including one position where the belt comes at an awkward angle that generally doesn’t work with high back boosters. We did find one seating position in one vehicle where the belt didn’t retract, but in general the Monterey would be an excellent bet.




If there is too much space between baby’s crotch and the crotch buckle, allowing baby to slouch down and potentially compromising the airway, try using a crotch roll (small rolled cloth or receiving blanket) to fill the space. Ensure first that the harness is adjusted tightly to pass the 


























Here’s what you need to properly use an Infant Thingy:











This 6 month old (from our original
UPDATE (summer 2016): the Argos has been discontinued by Graco, and replaced with an updated Nautilus that merges the best features of both! Check for it in stores!
The Argos is a forward-facing only seat that later converts to a booster — important to note that it does not rear-face. The Argos’ grey cover is smooth and silky with an added accent of beige polka-dotted trim. It’s comfy and well-padded, more so than an older Nautilus in our collection. The memory foam is sure to make any child’s derriere happy! It comes with harness covers, a crotch buckle cover and an optional body support cushion that must be removed by 35lbs. We did find the crotch buckle cover slightly fussy as it has a minimal amount of velcro on it, and didn’t stay attached as a child was removed. The built in cup holder and cubbies are perfect for snacks and small, soft toys in the car. The smooth bottom of the seat plays nicely with upholstery, leather included.

Height & Weight Limits:











Fllo scores high marks for aesthetics, and the new fabric on this seat is called Thunder — and it’s beautiful! “Thunder” is grey on a black frame (also available on a white frame for Foonf and called “Cloud”), and has a look like a linen suit but feels more like thick k-way (pretty sure I just dated myself there with that reference). Very sleek and classy looking, and will coordinate nicely in grey or black interiors. Easy to clean up as well as it is a Crypton fabric. Four year old girl child cried that it wasn’t pink, but sometimes mom or dad gets to pick.
Fllo has one manual recline position in each mode – accomplished by swinging the flip foot and then locking it into place. How it then sits in the vehicle will depend largely on the contours and compressibility of the vehicle seat, as well as your installation technique.

First editions of Foonf came with a single length crotch buckle, but later versions came standard with a 

























The Rainier comes out of the box set up for a larger forward-facing child – adding an unnecessary and potentially misuse-inducing element to parents who largely purchase this seat for its impressive rear-facing capabilities. If it were up to us it would come with the harness on the lowest setting, and the crotch buckle on the innermost position. READ YOUR MANUAL when you pull it out of the box to ensure the seat is set up properly for your child.
Let’s talk about width now, the biggest visual difference between the Radians and the Rainier/Pacifica/Olympia. Based on the Radian shell, the new seats ARE wider at the top. Peel back the cover and you’ll see the extra shell width and depth is due to this black plastic add-on. Adding approximately 3″ in width at that point it could mean the difference between a Rainier/Pacifica/Olympia fitting or not. Still nice and narrow at the base though, so WHERE that width is situated in your vehicle will matter very much.
When seats are in alternating directions the extra width won’t matter much: forward-facing Olympia (looks tippy but isn’t, just the camera angle), rear-facing Rainier with approved
The extra width could be the deal-breaker if the seats are all in the same direction. Not a chance of fitting another Rainier/Pacifica/Olympia into the middle spot, but the skinny-minny purple Radian RXT fit with a millimetre to spare. Note that in this particular vehicle you CAN have three forward-facing harnessed seats across the 3rd row as there are
How about fit to vehicle from a front-to-back perspective? Like the Radians, it is a large (and heavy!) seat when rear-facing, weighing in at approximately 26lbs. No noodles or rolled towels are permitted to make the seat

The shape of the ‘boot’ required for rear-facing can create some challenges or incompatibilities when installing rear-facing.
One aspect we love about these seats is the low profile, enabling easy loading of kids in and out, whether you are doing the hoisting or kiddo is climbing in and out themselves. However, that low profile — and low belt path — can also be problematic in vehicles with long buckle stalks. You MUST be able to install the seat safely and correctly with 1″ or less of movement at the belt path, and if the buckle stalk is going to run up into the belt path that could mean an incompatibility. With the high rear-facing weight limit of 50lbs, ensure that you CAN install with the belt in your car both rear- and forward-facing, as lower anchors (UAS, LATCH) come with a weight limit. Discontinue use of lower anchors at the weight indicated by your vehicle; if you don’t know what weight limit your vehicle states, switch to a seat belt installation when your child weighs 40lbs.

Teeny tiny! At about 8lbs this wee one fit beautifully with the included infant padding. The lowest harness position was approximately 1″ below her shoulders, meaning she could have been that much shorter in the torso and still fit.
4 months old and about 15lbs. Another nice fit!
