Removing lower tether straps

[Glystl]

Hello, I've an Avionaut Sky seat with lower tethers. Love it in every way but it's tethered so tight I'm finding it absolutely impossible to loosen the tethers
so i can unclip them and move it to another car (we have a spare set so i can leave the tethers themself in place.) Is there a nack to doing it? Driving me mad! Thanks so much

Can you undo the seatbelt and/or support leg first? That should give you a bit of extra slack.

Thanks so much, have released seatbelt and wiggled as much as can, just struggling to lift the catches that loosen the tethers. Gah at least it means it's firmly in place the rest of the time i guess! 😂
