We got this sofa for our rented apartment and are very happy with this purchase. The bed is very comfy to sit on and we also had to use it why waiting for our mattresse in the bedroom so we did use it quite a lot as a sleeping place. 
I would recommend it to anyone who likes a firm bed. I have back issues and I find it very comfortable. My husband is also 193 cm tall and he could fit on it. It’s a bit narrow for two people but if you are of average height and size you can use it as a sleeping place as well. The material is nice and it would be just perfect for a guest night sleep! Long, comfy and quite a stylish bed. It’s a very good value for money, for sure!!
