Wouldn’t worry about using the base for a next stage seat. There’s a handful you can re-use the bases on but they might not be suitable for your child. Look at Avionaut Sky, Avionaut cosmo and Besafe Beyong for infant carriers. Cybex cloud is very heavy and not all maxi cosi are very supportive
Thank you that’s all really helpful info
Yes as Emily said although there are normally better and safer car seats for next stage for the same price of the compatible next stage seat x
