Slept in recliner chair for 3 years

After I broke my ankle 3 years ago and was laid up for months, rather than the faff of making my way to my bed, I slept on my recliner instead.

Unfortunately I got so used to it when I was mobile again, I carried on. I’ve tried my bed a few times but end up waking up when I land on my back as I have chronic lumbar pain (probably all the years in the chair didn’t help.)

I don’t know what to do as I’m starting to not sleep well in the recliner either. Any ideas please?
