The Tetra allows for the use of a six point harness from birth through to a large four year old (approximately). The Tetra offers exceptional features and the highest level of safety at an affordable price. As an A4 rear facing restraint, allowing for extended rear facing through to a large 30 month old (approximately), and then front facing through to a large four year old (approximately).

The Tetra is nice and compact at 44 cm across the widest point. As a result of its compact size this child restraint is perfect for three across installations and small cars.

Belt Path:
The Tetra features an easy to use single belt path, making installation a breeze whether in rear or front facing modes. This means your child restraint can be installed in under a minute, perfect for if you frequently move it between vehicles.

Recline Positions:
The five shoulder harness slot heights and nine recline positions allow for an extremely broad range of children.

Air Cocoon Technology™ (A.C.T):
The Tetra features Air Cocoon Technology™ (A.C.T.) to enhance side impact protection through blow moulding design which dramatically reduces the impact forces during a crash. The blow moulded shell greatly reduces the forces on a child’s head and body in a side impact accident. Your child is quite literally cradled in a cocoon of air, offering a true 180 degrees of protection to your child’s vital organs.

Covers & Inserts:
We designed the covers and inserts for the Tetra so they could be easily removed with press stud attachments. As a result, cleaning is now easier than ever before. Our covers are made with plush and soft fabrics that are breathable and perfect for keeping your little one comfortable.

    Transition Swaddle

    This swaddle has been great now my daughter has her arms out. She still knows it's bedtime once it gets put on.

    Maxi-Cosi Vela AP Convertible Car Seat

    Fantastic carseat. Fits my little 6month old neice great (without the insert). I didn't realise it needed the tether strap and the isofix while rear facing, which is a bit fiddly. Length is smaller than other Maxi Cosi carseats we have which is a bonus if the front passengers want to have a little more leg room. Over all rating 8/10.

    Fantastic customer service

    The Nuna stroller is top quality.
    Winkalotts customer service has kept me up -to-date with my order and has helped out extensively with advice and alternative options when one or more items that I had ordered were not available on time due to shipping delays.
    Compliments for a fantastic customer service.

    Very Good

    Very happy with the scales, they’re super easy to use and accurate. They have easy to read digital screen, are easy to clean and easy to pack away when not using. We have been having feeding issues so it’s good being able to weigh baby at home (peace of mind that she’s gaining weight between plunket visits). I like the added bonus of having measurements in the bowl though I zero it with a small blanket in it so it’s not as cold/hard for baby but handy to have.

    Package arrived very quickly, very well packed. Communication was excellent. Thanks very much. :)

    Want more space? Get these

    We bought 2 of these for Mr 3 and Mr 4 and wow, we have a tonne more space in our car now. Boys love them. The harness is secure and they are comfortable for the kids to keep on and keep safe. Highly recommend A++++
