Recommendations for bed rails for travelling please?

[Lavender14]

Ds is coming 3 and we're going on holiday in a couple of weeks and as he's so big for his age he's not going to fit in the travel cot this time. So I'd like to try him in a single bed against the wall with a bed guard. It'll be a divan bed. Can anyone recommend something that would be light weight for carrying (hotel has no lift and I'll need to juggle him stairs and suitcase on my own) and that works well on a divan and is easy to fit and secure? He moves a lot in his sleep so ideally a longish one would be good!

Thanks in advance!

A pool noodle put under the fitted sheet. Failing that because it’s not always doable to fit a pool noodle in your suitcase, then roll up a large beach towel and you have pretty much the same thing. It works as a barrier to stop them rolling out. Then as an insurance policy, I’ve never had the towel/noodle fail us but just in case, I usually collect up whatever scatter cushions and spare pillows I can find and stick them on the floor next to the bed.

Thanks for the advice! Thankfully this time it's just a staycation so I'll be able to put a bed guard in my car and will just drive to the hotel so no issues with fitting it in a suitcase!
