Travel bed 7 & 3 year old

[Surviving68]

What do people use... ? We have sleeping bags but they're hopeless on a wooden floor...

We did buy Ready Beds but they can end up as a sweaty mess...

I'm stumped!

Something like this?

wow that looks amazing! 7 year old would probably grow out of it pretty fast though, he's quite long...

I guess I was thinking of something like a Ready Bed - just better!!, less sweaty and more stable. Not sure it exists though...

We use a self inflating mat and sleeping bag for our nearly 4yo but she does slide around a bit when on a polished floor.

Would you recommend your mat Adeline?
