Recommendations for either compact off the shelf sofa beds or bespoke sofa beds

[gobblygook]

We have a small space for a sofa bed - the extendable length can't be that long, but it needs to be a double.

We want it to be comfy, are willing to spend a bit of money as it will be used, but we're having problems finding compact sofa beds.

Any recommendations?

I recommend the Ikea Lycksele one - it looks weird but is very good for sleeping and OK as a sofa. DH and I have been sleeping on one for 3 months and it is surprisingly good for a sofa bed.

Another important feature of the sofa bed is if the bed can be pulled out smoothly. If it can't, you might as well continue looking for a sofa bed.
