We bought a sofa bed from furl 4-5 years ago. The cushion immediately sagged - we weigh 70 and 57kg respectively, so it can't be that were too fat. The material we used to upholster the sofa - admittedly our own, but from a manufacturer of far higher renown than furl - immediately looked creased. Furl blamed the material issue on the material, and stuff we weighed too much. Eventually they replaced the cushion, which sagged again and which we couldn't be bothered to replace again. So if you weigh more than 125kg as a couple, it's probably best to look elsewhere as we did. The spring mattress was good for a couple of years but again started sagging from occasional use. One star extra given for the fact they reluctantly changed the cushion. To be honest, having used IKEA sofa beds, you'd be better off buying one every few years and changing it - the furl sofa was only marginally better quality.
