I bought this car seat as I started suffering from back pain from carrying the baby in &out the car in the maxi cosi. It's a great car seat, easy to install and to use. I wanted a chair with a 360 spin, and after doing a lot of research, I decided to buy the Jane Gravity. I have not regretted it. The seat it is a bit bulky, but it has an amazing reclining and my baby is sooo comfortable.
We recently acquired the Jane Gravity i-Size for our growing baby and this has proven an excellent choice. Baby happy, the chair reclines just enough so he can sleep comfortably without head falling forwards. Easy to manoeuvre which really helps with getting child in and out of the chair. Secure and sturdy. Very pleased.
This car seat is incredibly easy both to install and use. It’s stylish, roomy and has lots of useful features such as the 360° rotation and the no-nonsense adjustable straps and headrest. But you do need to have ISOFIX in your car and it is pretty heavy so it’s not a car seat you can take out and about.
I'm trying to establish if it would fit in a Ford Fiesta Zetec (2010) and a Volkswagen Passat (2008). Both cars have ISOFIX available. I've looked at the official list of compatible cars but there are very few cars listed and I have to assume it will fit many more than that. Could you please help?

Hi, Gravity is compatible with both your cars, the list you saw was the original list at time of launch but it is increasing as more are tested.
Kind regards

Hi there, can you tell me where I can find you car compatibility checker? We have a 2010 Citroen C3 Picasso and I need to know if it fits.
Thanks
Johnston Prams Replies:
Hi Matt, the fitting list is available to download from our GRAVITY PAGE on our website, scroll down the page further.
It is a downloadable PDF file with the current list, of which your car is on and confirms the Gravity fits ok.
Hope this helps.

Is this car seat compatible with a 2003 VW GOLF? Thanks
Johnston Prams Replies:
The 2003 VW Golf Hatchback is on the pre-tested list of cars and the Gravity will fit fine.

The PDF download of the fitting list is available on this page which you can refer to and see OPEL listed.
Hope this helps.

We have two cars but don't want to buy two car seats. Is it possible to buy only a base for the Jane Gravity (iSize)?
Johnston Prams Replies:
Hi Lizzie, sorry but no, as the car seat swivels the base is built into the whole system to maximise its strength. It usually only infant car seats which have carry handles that have a separate base so they can be removed to be used outside the car on a chassis as a travel system. Bigger seats, the child would be too heavy and therefor car seats for older children tend to stay in the car.
ElizabethfromUnited Kingdomasks
We're very happy with our Gravity (iSize) car seat. Do you sell separately the anchor brackets which attach to the car's Isofix fittings?
Johnston Prams Replies:
Good afternoon
The anchor brackets are a fixed part of the seat and are not available separately.
Kind regards

How wide is the car seat?
I need to fit and an adult in the back seat and so need a narrow size 1 car seat.
Thanks
Johnston Prams Replies:
Good morning
The widest part (the arm rest area) is 44 cm in width across.
Kind regards

Are Jane interchangeable eg can a crosswalk seat go on a trider base?
Johnston Prams Replies:
No, Each pushchair seat unit is designed for their particular chassis. This is so they can fold with the chassis and are also stable, as some chassis and pushchair on the Jane range are higher off the ground than others.
The Jane car seats can go on different jane chassis or pushchair, but not the pushchair seat units.
hope this helps.

Will this car seat fit in a Seat Ibiza?
Johnston Prams Replies:
Yes your car has been tested with the Gravity iSize car seat and fits perfectly well.
In fact the Gravity will fit all modern cars that have ISOFIX and the only things to check for, as with all car seats, is that any AIRBAGS are switched off on that seat position, and that the floor in which the support leg is placed onto is solid; no underfloor compartments.
If it does have a compartment, then you need to speak to your car dealer for a filler, or check that the support leg can extend to the solid floor of the compartment.
GrantfromUnited Kingdomasks
Hi, I can't see Lexus on your list of approved cars for this product. I know we have isofix in it - it's a 2007 GS300.
Do you know if it's compatible?
Johnston Prams Replies:
Unfortunately Jané have not got round to physically trying the Gravity in your model of vehicle yet. However the Gravity will fit all modern cars that have ISOFIX and the only things to check for, as with all car seats, is that any AIRBAGS are switched off on that seat position, and that the floor in which the support leg is placed onto is solid; no underfloor compartments. If it does have a compartment, then you need to speak to your car dealer for a filler, or check that the support leg can extend to the solid floor of the compartment.
