Is the bugaboo bee 5 carrycot mattress the same shape as the bee 3 one?

[brushlaptop]

Just about to have baby 2 and it's been pointed out that I need to get new mattresses for everything!

We have a bugaboo bee5 buggy, does anyone know if the carrycot for the bee 5 is the same size as the bee 3? I can find loads of mattresses online for the bee 3 but none for the bee 5 so wondering if they are the same size!

I’m not sure sorry but if you struggle to get an answer I would contact bugaboo via email - their helped me with a similar question re car seat adapters from my bee 3 to 5 and were really helpful.

Thank you!
