The safest place for your child in any vehicle is in the back seat.  The center of the rear seat is preferable to outboard positions, as long as you can achieve a tight installation, because it is the furthest from a side impact.

Infant Carrier
Restraints manufactured to AS/NZS1754-2004 - When your child's shoulders are level with the top slot of their Infant Carrier it is time to move into a larger seat.
Restraints manufactured to AS/NZS1754-2010/2013 - When your child's shoulders reach the shoulder height marker to change to the next suitable restraint or forward facing mode.

Convertible Car Seat
Restraints manufactured to AS/NZS1754 - 2004 - Your child is too big for a Convertible Car Seat when their shoulders are 25mm above the top harness slot.
Restraints manufactured to AS/NZS1754 - 2010/2013  - When your child's shoulders reaches the shoulder height marker to change to the next suitable restraint or booster mode.

Booster Seat
Restraints manufactured to AS/NZS1754 - 2004 - If your child’s eyes are above the top of the Booster Seat back when seated, this is an indication to move to the next form of seat.
Restraints manufactured to AS/NZS1754 - 2010/2013  - When your child's shoulders reach the upper shoulder height marker to change to the next suitable restraint.

Booster Cushion
Restraints manufactured to AS/NZS1754 - 2004 - If using a Booster Cushion with no back (e.g. Nova) then the child’s eye level must be below the car seat back or headrest when the child is seated.  
The introduction of the AS/NZS1754 - 2010 saw the deletion of Booster Cushions due to their inability to provide side impact protection. Safe-n-Sound ceased manufacturing booster cushions in 2011.

Each child restraint seat has a flame retardant cover which can be removed for cleaning. Cleaning instructions are on the care label attached to the cover. All child restraint seat covers are machine washable (gentle cycle), cold water only, rinse well, dry on flat surface, do not tumble dry, bleach or dry-clean.

Neck pain NO more!
Size: 2.7"H (Queen)
Favorite!!!! Fantastic pillow! It is not real high, so your neck stays in a proper, and comfortable angle to your spine!!! It’s soft, BUT not to the extent that your head sinks down. I have arthritis in my neck, and this pillow is SO COMFORTABLE!! I wake up with no pain in my neck. It is not memory foam, it’s latex, so it remains cool. I normally sleep on my back, or stomach, and either way, it’s great. When I sleep on my side, I add an additional small pillow. Nothing but high marks from me for this quality pillow. I love it! I’ll buy a smaller one for travel.

The Best Pillow I Ever Slept On
Size: 2.7"H (Standard)
I can't say enough about how wonderful this pillow is I am a side sleeper and I have to say since purchasing this pillow I have had the best sleep that I have had in years! The problem I had with most conventional pillows was that they would be so thick and poofy that my eye that was against the pillow would get buried in the pillow Loft and I would wake up the next morning with a dry scratchy eye and it would take hours for that Vision to be completely normal. This may look like it is incredibly thin and it is thin but not too thin if you are a side sleeper it is the perfect thing. The resiliency/bounce of this pillow keeps your eyes from being affected by the pillow Loft perfectly aligns your head neck and spine and it is also incredibly cool to sleep on no more waking up with your face and hair matted in sweat. The only downside of this pillow is that it does have a fairly strong rubbery smell but I found that after about 2 days that pretty much completely goes away. It is so completely worth dealing with that rubbery odor for a couple of days for the amazing comfort that this pillow brings along with a truly great night's sleep I wish I had known about and bought it years ago I will definitely have these on my bed as long as they are available to purchase I highly recommend this to anyone who is a side sleeper and anyone that is looking for a pillow that is tremendously comfortable and cool to sleep on I would give it more than five stars if that were possible!

It Is Slim But Very Firm With Virtually No Give
Size: 2.7"H (Standard)
I bought this pillow hoping that it would lift my head gently but not push it forward. They said in the description that it was soft but it isn't, it's really quite firm and no ones head is going to sink into it hence it just pushes it up. Now if that's what you are looking for, then you've found your pillow. They were very good about the return and it is packed very well and very nicely.

Great toddler pillow
Size: 2.7"H (Standard)
We decided to get this for a toddler pillow for our son. I'm a little intense about what kinds of materials he is exposed to and I feel comfortable with latex. The pillow cover is synthetic and I'm not sure how I feel about that, but it is removable. It seems really comfortable for him--supportive but soft. He loves sleeping on it. And I don't have to worry about him burying his face in an ultra lofty pillow that would be making me nervous all night. I might buy one for myself and my husband at some point too!
