Frequently Asked Questions

At what age is my child ready for a belt-positioning booster like the Tanza?

The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.

Can I install the Tanza without the UAS connectors?

The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.

Is the Tanza allowed on airplanes?

Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues. The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area. One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure. The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly. Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.
