Assembling this chair bed was quite challenging with some of the very heavy duty bolts not quite lining up at times. None the less this seems like quite a robust and solid piece of furniture once assembled. For sitting on as a chair I find it quite firm but comfortable. The procedure for folding it out to become a bed could hardly be easier and so far the mechanism is very smooth. It has not been used as a bed yet so can’t comment on whether it’s is comfortable in this respect. All in all I’m pretty impressed and pleased with my purchase. It looks good in my small study bedroom.
