Has anyone ever found a sofa bed that’s actually comfortable as a bed?

Hi.
In an attempt to make some more living space we’re thinking about turning our downstairs spare bedroom into another seating area. But still need to be able to put guests up.
Has anyone ever got a sofa bed that is actually comfortable both as a sofa and a bed? It won’t be used as a bed more than 5 or 6 times a year, but elderly parents need to be comfy!
Thanks for any advice.

Also agree with Furl, have only sat on one never slept on one but they have excellent reviews. ££££ though.

The other thing we're considering is a Murphy type bed (a wall bed) as they use a standard mattress so literally the same as whatever you'd have on your normal bed, and then a normal sofa but appreciate this might not be a solution for you.

We have a Futon company one, which is designed to be a daily use bed (though we use just for guests) - the mattress is fab, really comfy (and firm which I like). It makes a big sofa too as it is the length of a double bed and the mattress forms the back and seat (no arms)

I'm looking for a sofa bed for my daughters room. It fits a small double bed in but little else. She's 12 and spends half the week with me
