  • Car Seat Cup Holder

Installation with base: Pay attention to the i-Size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-Size child seats and will therefore not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.

Up to 50% higher safety levels*

Rear-facing is one of the safest ways to travel. In the critical first moments of a front impact, the child's body is pushed against the padded car seat shell, minimizing movement and reducing the force acting on the child's neck. Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for comfortable rear-facing travel until your child weighs 20 kg.​ (*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.)

Quick and easy onboarding

A stress-free start to your journey. Just swivel the car seat to face the car door and get your child onboard. You avoid back strain, while your child stays comfortable in any recline position.

Optimal breathability

Comfort in any season. All-round air ventilation lets air flow through channels in the car seat, carrying away heat and helping avoid a sweaty ride for your little one. The Plus version also includes mesh fabric that increases breathability up to six times compared to regular fabrics.

Side-protection

Integrated Linear Side-impact Protection defends your child against the force of a side impact. Working together with the energy-absorbing shell, the L.S.P. System significantly reduces the effect of impact force on the child.

Always in a comfortable position

Find the ideal recline setting, whether your little one is a newborn or a growing child. Five positions are available in both riding directions – and in the boarding position, too. And when your child falls asleep, you can recline the seat with one hand, letting them dream that little bit longer.

Grows with your child up to 4 years old

As your baby grows, adjust the Sirona Gi i-Size headrest for a comfortable fit at every stage. 12 positions allow a tailored fit to your child, with the harness lengthening automatically with each adjustment - and only one hand is required.

Easy onboarding

When you’re getting your child strapped into the car seat, you need all the help you can get. The Sirona Gi i-Size features ingenious loops designed to keep the harness out of the way as you get your child onboard. Switching from rear to forward-facing is just as easy.

Straightforward installation and anchorage

It only takes moments to set up your Sirona Gi i-Size. Use an ergonomic handle to click the ISOFIX into the vehicle seat and extend the load leg. Both provide stability and extra safety. Visual indicators help you confirm the seat is ready to protect.

Almost perfect, absolutely fit for purpose, and a great value
Size: Standard--black
These are really, really close to being five stars, but because of my OCD tendencies when it comes to things being true and level, I can only go four. The way these mounts are made, speakers rest inside and on the inner surface of the L-shaped adjustable side brackets, and not on the large metal plate between them. Leveling on the fore-and-aft plane can easily be handled via the adjustment nut on the bottom of the bracket. But there is no provision for side-to-side leveling, so if the manufacturing of the side brackets is not within tolerance, you'll wind up with a speaker that's ever-so-slightly wonky...which is the case with ONE of my mounts. The bubble is still between the lines, but it's kissing the left line. Most would not care about this, and I'm not too bummed about it, but I am able to see that much out-of-true with the naked eye. It's not enough to pursue any kind of remediation, because the value on these really is awfully good. They are solidly built, easy to install, and easy to adjust. The manufacturer is apparently improving the product as they go based on feedback, as some issues that have vexed other owners have not been a problem for me, such as the wall plates being or coming loose (the design now ensures they stay put once pushed back to the wall), or the adjustment nut and bolt rotating freely and not staying tight (the ones on mine are great and function as intended). For the price, these are really hard to beat, and I have a feeling all the mounts like this with the different oddly-named brands are made in the same factory. That being the case, get the cheapest ones, and the day I bought mine, these were those.

Solid and easy to install
Size: Standard--black
These are nice, solid wall mounts. They assembled quickly and easily, and they can hold larger bookshelf speakers like my Cambridge Soundworks M60s. Adjusting the plate to match speaker size is pretty easy, and they seem to grip the speaker tight enough that they won't fall off. The tilt option is very useful and a good feature when speakers are mounted high and need to tilt down toward the listener. Just remember to tighten the bolt on the bottom once you've positioned it where you want it. I would definitely recommend these to anyone looking for solid, well priced speaker mounts.

Sturdy solution
Size: Standard--black
I needed a way to mount rear speakers and this was the solution. They're sturdy and adjustable to fit reasonably sized speakers. They also pivot up and down and swivel so really perfect.
