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.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

The most perfect pillow!!!
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I have spent so much money over the years, 14 years to be exact in trying to find the perfect pillow. I have finally achieved that by buying this amazing memory foam pillow. What I've been searching for is this exact pillow. It's firm, but yet soft and so comfortable. It forms to your head and shoulders. I don't constantly wake up in the middle of the night to fluff my pillow, this pillow stays fluffed throughout the night. The price is a steal and bcuz it's been so hard to find this perfect pillow that I first bought 1 set to try it out and ordered another set right away. I have total of 4 of this amazing pillow. Thank God literally, I am finally done buying pillows. Thank you Amazon for the best purchase ever!!!!

Feels amazing
Color: White, Size: Standard (1 Pack)
This pillow has completely transformed my sleep! From the very first night, I noticed how comfortable and supportive it feels. The filling is just right — not too firm, not too soft — and it cradles my head and neck perfectly, helping me wake up without stiffness or discomfort. I’ve tried several pillows over the years, but this one stands out for both comfort and quality. It stays fluffy throughout the night and doesn’t flatten like some others do. The cover is soft and breathable, which keeps things cool and comfortable even on warmer nights. Overall, this pillow offers excellent comfort and support at a great price. Whether you’re a side, back, or stomach sleeper, I’d highly recommend giving this one a try — it’s helped improve my sleep and I’m very happy with it!

Affordable, but lower quality than I expected
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I had an adjustable pillow that came with white, soft, shredded foam with fibers. It was super comfortable. When it came time to replace that one, I specifically chose this OAISZ pillow based on the listing photos that show this has white, soft, shredded foam with fibers. Unfortunately, what I received was low quality blue foam chunks with no fibers. The foam has thick, stiff edges that I can feel. While I was filling the pillow with the foam chunks, I noticed the outer pillowcase had stitching unraveling. The pillowcase feels cool at first, but then it heats up. Overall, these are affordable pillows for a set of two. However, they are low quality. The pillow is comfortable enough to sleep on, but I’m disappointed that the filling is not what is shown in the listing photo. UPDATE: The seller reached out to me after I left the above review and proactively offered a refund which I appreciate. I have revised from 3 stars to 4 stars as a result. The product was not for me, but the customer service was outstanding.
