Carpet underlay - enough for a large room (Wetherby LS22)

We are going to replace the carpet in our living room with a wooden floor. We are repurposing the actual carpet but will have a large amount of underlay which may come in useful to someone. It appears to be in very good condition. The room measures approximately 4.6 metres by 5.7 metres. The floor fitters are coming on 7th August so the underlay would have to be picked up on Sunday 6th. The room will be empty of furniture but you will have to help to take the underlay up.
