@Natasha388 I have both in my listing: one pullout sofa and one klik klack style futon from Ikea. They don't make the same model anymore, but it's like this:

I have the best mattress option they have available, the pocket coil version, and I find it to be more comfortable than the pullout. The mattress is way thicker. As a back sufferer, I hate most beds: I've never found a pullout or futon I'm really happy with, and most of them are torture. However, I've slept on that same Ikea one at a friend's on a number of occasions, and it's the best I've found. Any pullout I've found just has a really thin mattress: it's impossible to avoid. You could try offering a memory foam topper, but trying to get people to put sheets on the bed, let alone a topper, seems challenging enough.
