Toddler Bed/Pillow

[Redruby2020]

Hi all, my DS is 3 early next year, and I am looking at options in terms of a bed going forward, until now he has been in a full size travel cot, several reasons but had a proper mattress and was very comfortable, but obviously as it is not possible to take parts off etc like a cot bed etc, then in due course he will need something else, so any suggestions welcome please.
The other thing is, he has taken a liking to my pillow, and I have been thinking about buying one for him, I have had a look at pillows for his age group, and jumped at some of the what looked great and under a tenner, but then read the reviews and thought no. Obviously I would want to get something decent and supportive, so don't mind spending a bit more.

Mine went straight to a single bed and had a normal quite flat pillow from age 1

DS was in a full single bed from 2 years old. I got one lower to the ground so he found it easier to get in and out and put a bed guard on to stop him falling out

I’ve also given him a full sized pillow - just a fairly flat one as think that’s the main selling point of a toddler pillow

Thank you, as I am not sure if I got notifications telling me I had replies I didn't come back and check.
When I first read single bed I was like woah lol, as I can just imagine my DS lol jumping up and down on his. And yes the side guards would be needed very much so!
