Are Sofa Beds Comfy To Sit On

I have two sofas that we bought from sofa workshop in 1999.
Are sofa beds comfy to sit on. I m just buying new covers for them because after 9 years they have finally worn out. They are particularly useful for homes that accommodate lots of guests. One is a sofa and the other one is a sofa bed. However it is not pocket sprung.
A decent one should serve you as a settee for entertaining and relaxing a spare bed for guests staying the night. It was rustic but on the ocean. Clic clacs are bed ready in seconds. Read my opinion based on sleeping on quite a few futons whether futons are comfortable as a bed and or a sofa.
Sofa beds for example are a thing. Sofa workshop insists this is for one off guest use and that the everyday sofa bed mechanism has a 10cm thick mattress and wooden slats. Unlike other sofa beds they take up little space but do provide a comfy place to sit and sleep. Our favourite feature of all though are slipcovers.
When we arrived we loved the setting the view and the accommodation. Best sofa beds for smaller rooms and tight spaces clic clacs. Then we went to bed. They have the added advantage of having a flip down mattress which locks into place to form an occasional bed surface.
About 5 years ago we stayed at a cabin. Both are still going strong and comfortable to sit on. A sofa bed promises a cunning space saving solution for all your hosting problems.
