First off, Furl sofabeds are no in any way inexpensive. You can get a sofa bed for a fraction of the price. However, that is where the comparison ends. The sofa beds from Furl are (in the main) hand made and of very good quality. The actual sofa part is comfortable to sit on and serves well as a sofa (unlike some sofa beds where the cushions 'collapse' when you sit on them. The sofa bed mechanism is superb and one of the best (if not THE best), that I have seen. The action is flawless and easy to operate, even if you don't have huge upper body strength. We had house guests for several weeks sleeping on this and they could not say enough good things about it. We upgraded to a pocket sprung mattress, which provided additional comfort (in my opinion). A superb product that proves (as per my first line), that you do indeed get what you pay for. Also, don't be concerned about unusually narrow doors. The sofa is delivered in component form.. the mechanism is on one piece, but other pieces 'join on' and can be easily removed if moving rooms or house. Assembly was easy, as we paid extra for it, bit it should be possible for someone with basic DIY skills. The delivery crew actually work for Furl, have a Furl branded van, etc. You are buying Furl and it is installed by Furl, so even the delivery and assembly guys have a sense of pride in the company and product. We will certainly buy from Furl again.
