Advice on creating a nest or comfortable sleeping thing for the lounge

[hotpot]

My DS2 has severe reflux and although he is sorted with pharmacy formula he still sleeps on me in the day (a residual behaviour from when I had him propped on me to sleep as he couldn't lie down due to the reflux)
At night he sleeps in his cot (hoorah) at around 5am he wakes and I take him into bed with me. All fine.
I am trying to make a "nest" or comfy place for him to sleep in the lounge so that I am nearby in case he wakes. I can't traipse my pram in because I have steps at the front of my house so would have to trek the pram through my garage, utility, kitchen, dining room and then into the lounge (you can tell a man designed my house!!!)
Can anyone suggest something comfy for him to sleep on. He is 7 months so I can't do a beanbag. I did see this but the company states it is a chair and not to be used as a bed (think it might be to do with regulations)

A friend of mine had one fo those little pop up travel cots for this very purpose tucked in a corner of her lounge - not sure her DD slept in it very often though!

Others used those padded bouncy chairs.

I used a Babybjorn bouncy chair with DS but it was summer.

What about This?
Converts into a chair for toddlers so it will last a while.

i used a travel cot, but that's made room for the christmas tree atm.

This would do but is expensive!

Thank you for your suggestions, Deck the blooming marvellous one looks good but it is costly. Also could he sleep on it without rolling off? It does look comfy though!

I have a 3.6yr old so I need something safe and away from him and his running around.

At what age can I use a beanbag?
