Revive your Current Life of Riley Bed - Pick a part.
After some time of your dog sleeping on its Life of Riley bed you may think the bed needs a bit of TLC - maybe a bit more fluff in the filling or a new cover to replace the worn one.
A whole new replacement inner has 2 layers of wool inside but you can also buy an inner with 1 layer of wool and add it to your current inner. - It will give the bed just enough extra bounce that it needs to make it like new again.
Instead of buying a whole new bed - pick the part you need and make your old bed look like new again.
