Product Features

  • UP TO 50% HIGHER SAFETY LEVELS - The Sirona T i-Size provides superior protection in both travelling directions in the case of an accident. When in the rear-facing position it reduces the risk of an injury to the child’s neck and head, resulting in 50% higher safety levels*. In the case of an accident, the child is pushed towards the seat shell, where forces get distributed over the entire surface therefore reducing the impact. Legally a child must stay rear-facing until at least 15 months and 76 cm in height but we recommend using it for longer, up to four years if possible. The Sirona T i-Size’s versatility allows for forward-facing positioning once the child has grown, offering freedom of choice that suits you and your child.
  • ALL-ROUND AIR VENTILATION SYSTEM - COMFORT FABRIC - The Sirona T i-Size breathable materials keep your little one cool.
  • 360° ROTATION - EFFORTLESS ON & OFF BOARDING - With the Sirona T i-Size, you can effortlessly on and off-board your child, thanks to its 360° rotation that smoothly rotates towards the car door. This feature minimizes any potential strain on your back during the boarding process. Legally a child must stay rear-facing until at least 15 months and 76 cm but we recommend using it for longer, up to four years if possible. Once your child has grown, you can easily choose between the rear or forward-facing position. It’s so simple, using just one hand, the seat can be smoothly rotated and reclined, ensuring that even the youngest passenger is comfortably boarded.
  • FROM BIRTH TO APPROX. 4 YEARS - Thanks to its height-adjustable headrest, the safety of the Sirona T i-Size evolves with your child, accommodating their rapid growth. With its 12 different positions, the car seat adapts to your child’s size during the first four years, providing steady protection throughout this time. When adjusting the headrest height the harness adjusts automatically to ensure a comfortable fit.
  • 25% MORE SIDE IMPACT PROTECTION - The Sirona T i-Size is equipped with the proven Linear Side-impact Protection System (L.S.P.) which enhances safety in the event of an accident. Activate the L.S.P on the side of the car seat nearest the door, together with the energy-absorbing shell of the seat, the extended side protection reduces the initial impact forces by up to 25%**. If needed, the L.S.P. System can be easily stored away in the case of limited space in the car.
  • INTUTITIVE ISOFIX BASE T - The ISOFIX Base T serves as a secure base for the Sirona T i-Size seat unit. It is equipped with ISOFIX and a load leg for easy and secure installation. The ISOFIX release buttons are user-friendly and intuitive, visual indicators confirm the correct setup on both the ISOFIX buttons and Load Leg. With these features, setting up the Sirona T i-Size is as easy as it gets, reassuring parents and providing a safe and comfortable ride.
  • COMFORTABLE SLEEPING POSITION - The five recline positions of Sirona T i-Size can be easily adjusted with just one hand, freeing up your other hand for different tasks. This feature works in both rear and forward-facing positions, providing additional comfort for your sleeping child while travelling.
  • HARNESS MAGNETICS - Small magnets located on either side of the Sirona T i-Size, allow you to attach the metal parts of the harness, keeping the straps out of the way for a simpler the onboarding.
  • NEWBORN INLAY - SUPPORT FOR SMALLER BABIES - The Sirona T i-Size includes a removable newborn inlay which provides a near-flat lying position, allowing for the use of the car seat from birth in the rear-facing position. The inlay helps keep the baby’s head in the most ergonomic position, especially while sleeping, to avoid breathing complications. To accommodate your baby as it grows, the newborn inlay should be removed once your child is taller than 60cm.
  • COMPATIBILITY - The Sirona T i-Size is compatible with the CYBEX Base T and Base Z2.

Soft, Warm and Cozy
I have no idea how these stay up, probably magic. I'm tall so it's challenging to find boot style slippers that are long enough. If support or thick soles aren't an issue, these are the best I've ever found! My ankles and calves have never BEEN so warm; these are my go-to's in the evening. They're easier to walk in with socks but, without, they're floppy and loose. I'd hesitate to size down because it's more the lack of structure in the foot, not length. They wash well (air dry); still soft, warm and cozy. Inserts could probably be added to help with support. I tried them because I found them at a fantastic sale price but I'm buying another pair now, for winter. I'm a slipper person and I definitely notice the quality of materials in Acorns, when I compare them with other slippers.

My year round footwear
Size: 6.5-7.5, Color: Sunset Cable Knit
I literally LIVE in these "slippers". Inside, summer, winter, outside when I can. I have hardwood floors, so even summertime, they protect my feet. They give me enough cush, but not like structured slippers that feel more like shoes. I go through about 2-3 a year, but well worth it.

Weird sizing
Size: 5-6, Color: Charcoal
Weird sizing/ fit! It says that they run large in length, so I got one group-size down (5-6). (The sizes are in ranges rather than specific individual shoe size numbers). I liked the concept of the suede reinforced toe & heel for longevity. My heel and toes cleared the length/width comfortably/well and the overall width was more than adequate, yet I found them to be rigid-stiff- tight (to the point of cutting off circulation) specifically in the toe. Ok, I knew that was a possibility BUT……while the toe area was tight the ankle and calf were HUGE and would not stay up unless I wore over pants, defeating the purpose of a slipper-sock. The inside cushioning was soft and comfortable. When I walked, my heel would slip out over the sued area, into the wool sock parentheses, making it awkward to walk. Returning…No point in changing sixes, as if I get a larger foot size, the tow may fit better, but the ankle will be beyond too big. Sigh. Unfortunate, as the concept is sound….the manufacturing/sizing is bizarre. BTW : I have normal width feet (not wide or narrow) and my ankles and calves are on the thinner side. The fit may be better suited to people with wider ankles/calves????

So cute
Size: 8-9, Color: Charcoal Faux Fur
These boot slippers are super cute and comfy warm. Fit true to size. Inside is real soft and warm. No, they do not offer support....they are slippers after all. The fur does not go all the way around the back. The back is just the woven sweater material but I imagine they would have zero stretch if the fur went all the way around. It may not be as cute without fur all the way but they probably wouldn't stay up if they didn't have the stretch material in the back so your only choice would be to let them slouch. I can pull them all the way up and they stay, I can do any degree of slouch and they stay so I see this feature as purely functional. Love the 2 tone with the suede around the toe and bottom but this is where my only complaint comes in is the sweater material right above the suede toe looks puffy so that part looks a little silly but otherwise they are absolutely adorable, comfy, warm and as functional as a pair of slippers can be. I wore them out in light rain and my feet stayed dry. The bottoms are like a rubberized fabric so they may soak through if you're in constant wet. Traction is surprisingly good even though it doesn't have a lot of tread. Overall i love them.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
