Expert advice

The Cybex Sirona T i-Size is the perfect follow-on car seat once your little one has outgrown their infant carrier like the Cybex Cloud T or Z2. Designed to keep your child rearward-facing for as long as possible (which is the safest position), the Sirona T offers comfort, ventilation, and clever usability features for daily life. The 360° rotation makes strapping in your child a breeze – no awkward bending or twisting needed. If you’re already using the Base T or Base Z2, this seat clicks straight on – making the transition seamless and cost-effective.

It’s a great long-term investment, keeping your child safe and snug from birth up to approx. 4 years old.

What We Also Love..

  • 360° Rotation
    The seat rotates a full 360 degrees when used with the Base T or Base Z2, letting you turn the seat toward the car door for easy access. This makes getting your child in and out of the car much easier – no more straining your back or awkwardly reaching around!

  • Extended Rear-Facing Safety
    The Sirona T allows your child to remain rearward-facing from birth up to approximately 4 years old. Rearward-facing travel is proven to be up to five times safer for young children in the event of a collision, especially for protecting their neck and spine.

  • Superior Ventilation
    All-round air circulation keeps your child cool and comfy year-round. The Plus fabric version steps this up with special 3D mesh panels that increase breathability by up to six times – perfect for long journeys or warmer weather.

  • One-Handed Recline
    Adjust the seat’s recline position with just one hand – ideal when your child dozes off mid-journey. It offers 5 reclining positions when rear-facing and 3 when forward-facing, so you can find the most comfortable position every time.

  • Grows With Your Child
    The 12-position height-adjustable headrest ensures the car seat adapts as your child grows. The harness automatically adjusts with it, so there’s no need for fiddly strap rethreading. It also comes with a soft newborn inlay for the early months, which can be removed once your baby is around 60cm tall.

  • Side-Impact Protection
    The integrated Linear Side-impact Protection (L.S.P.) system, combined with the energy-absorbing shell, reduces side-impact forces by up to 25%. This gives you peace of mind knowing your child is protected from every angle.

  • Travel System Continuity
    If you've already been using the Cybex Base T or Base Z2 with your infant carrier (like the Cloud T), there's no need to buy a new base. The Sirona T clicks right in, saving you both time and money as your child transitions to the next stage.

super - amazing - but not perfect - Denon AVR-X1800H 7.2 Channel AV Receiver
Style: AVR-X1800H
super - amazing - but not perfect - Denon AVR-X1800H 7.2 Channel AV Receiver - 80W/Channel, Wireless Streaming via Built-in HEOS, WiFi, & Bluetooth, Supports Dolby Vision, HDR10+, Dynamic HDR, and Home Automation Systems - There are many aspects of the Denon AVR-X1800H Receiver that are amazing. However, the Denon AVR-X1800H Receiver does exhibit some flaws. Despite the flaws, the Denon AVR line of receivers is probably the most practical option available. - setup - the on screen setup, using HDMI to an HDTV, with speaker testing is amazing! - audyssey - I could not get the Denon Audyssey system to produce anything that approached a reasonable experience. I disabled that feature. With audyssey disabled, I have been able to fine tune a wonderful sonic experience. - HDMI passthrough - as wonderful as this feature ought to be, it turns out that it is terrible. First of all, it demands to try to "upscale" all inputs, to a minimum of 2160p. With several computers that I want to display on my big HDTV, including a home data archival server, running the HDMI output from the computer through the Denon creates a completely distorted looking result. It's visually atrocious. - web interface remote control - this is a GREAT feature. Most importantly, the Denon can be controlled directly from any computer by finding the IP address of the Denon on the LAN and simply pointing to it. This is amazing! - Android / iOS remote control - the control interface via the Android OS app is the best and easiest way to operate, control, and adjust the receiver! - sound quality - super overall - running a 7.1 channel setup, using Monolith brand speaks I also purchased on amazon, the surround sound experience is extraordinary. Using the Android or Web interface, I can adjust the levels of individual speakers to fine tune the sonic experience for each movie. The speakers are: Monolith T5 pair front - Monolith T4 pair rear - Monolith D5 front center - vintage (1984) Klipsch KG4 pair secondary front - ELAC SUB1225 Subwoofer. - note - the Denon AVR-X1800H is actually in the middle of the range or the similar receivers that Denon markets. However at this price level the Denon AVR-X1800H already provides what most people need. The addition AVR-X4800H AVR-X5800H AVR-X6800H provide more channels, and more "power", but they seem to maintain similar features. - Heos - have not used it and do not need it. I play all music via an HTPC dedicated computer running vlc media player, iTunes, Kodi, and so on HDMI erac output into the Denon for audio output. - conclusion - overall, except for the nearly unusable HDMI passthrough feature, the Denon AVR-X1800H is delightful. -

Do Not Buy Denon Products
Style: AVR-X1800H
In search of a new A/V receiver, I sought recommendations from my friend, a professional custom home theater installer. He strongly suggested a Denon model, citing its exceptional quality and robust customer support. Regrettably, my experience with this receiver has been diametrically opposed. Upon connecting all components and completing the setup instructions, the unit commenced malfunctioning immediately. Subsequently, when all components were shutoff after I finished watching a program, the receiver turned itself back on. Occasionally, it would also turn on the TV too. Fortunately, I was present during these occurrences. I contacted Denon support, providing a comprehensive description of the issue, including the steps I had taken to resolve it, which entailed restoring the unit to its factory settings. Regrettably, the support representative was unable to provide any information regarding the underlying cause of the problem or offer a solution. When I informed him of my option to return the unit until January 31, 2026, his response was that this may be the most appropriate course of action. Upon looking at reviews of this receiver and Denon receivers in general, this has been an ongoing issue for some time. Therefore, I would not recommend purchasing Denon products.

Easy Set Up and Great Sound Distribution
Style: AVR-X3800H
I replaced an old Onkyo 535 with this Denon. It was a significant upgrade. There is zero noise, the Bluetooth is easy to use and provides excellent sound, and the HDMI circuitry is outstanding. The eARC capability is compatible with 2.1 HDMI, and it works seamlessly. Of note, I really like the way it provides the best sound configuration automatically for each source, and I don't have to switch around to find the best sound option. For example, if the source is compatible with Atmos, it provides Atmos. If it's only compatible with Dolby surround, it switches to that. Finally, the distribution of sound is superb. I have a 7.1 speaker configuration of mostly mid-level speakers, and the Denon uses them to their fullest. Rear sounds come clearly from the rear...same with each side, etc. And most of all, I don't have to tweak the system to get that. I just used the provided microphone and ran the set up (which was really easy), and I have really great sound. This unit is a good value.

Expensive, but nice
Style: AVR-X4800H
I previously owned a Denon AVR-2808ci since 2008. That model's remote control didn't work well, and all controls were unnecessarily convoluted, so I was hesitant to buy another Denon. The thing that made me give them another chance is that the sound quality was nice, and I was hoping their engineers learned from their mistakes. I'm glad I gave them the chance. This new model, the AVR-X4800H, also has excellent sound quality; however, unlike the old one I had, the controls on both the receiver itself, and especially on the remote control, are significantly improved. The controls are intuitive, and everything works perfectly. That alone made me happy with the purchase; however, the ability to run 4k @ 120 hz for video gaming, and with extra HDMI ports they have here, all added to that value quite a bit. Then, in addition to that, the old model I had ran super hot. In fact, so hot, from just basic usage, it fried itself three different times in the span of a couple weeks (during the winter time), and it kept being repaired under warranty, until they replaced the top grate with one that allows more ventilation. However, this new model doesn't appear to suffer from that same issue. It gets pretty warm, but nowhere near what the old one did -- and I'm using the same Bose Surround Sound system with the new one. That said, as a precaution, I went ahead and ordered an AC Infinity AirCom to put on top of it, to assist with cooling/ventilation, which has worked wonderfully as well. No the tempts on this Denon AVR have never gone above 87 deg, even on a warm room on the third floor during the late spring / summer time. The other hesitancy I had was the price tag. I only purchased it because it was on a "25% discount", from $2500 down to around $1850. Granted, it was similar when I purchased the other one 15 years ago, but it's just an awful lot of money, in my humble opinion. I would say it was borderline on whether I would buy it for this amount, and if it went up at all, I wouldn't have purchased it. I may not purchase it again for this price, especially if I have one already that is working well -- it was only the wonky one that I already owned, that I just wanted to get rid of, that put more pressure to give them one more chance. With a working device, I probably wouldn't pay these prices again. But, if it were a few hundred dollars cheaper, then I probably would buy it again. Hopefully this helps someone. It's a great device, just a bit expensive. And, if you get it, I would still recommend getting a top cooling fan for it.
