It’s so simple! Keep heavy blankets off my feet and enjoy the limited mobility I have! I’d been restricting any ankle movement beforehand! I have a single bed with a double sized duvet- the cage lifts the duvet but there’s still plenty left to drape down the sides so no drafts get in - I need to be kept warm and this cradle is just the best; I’m very warm and I can turn my legs again! Quick delivery and reasonable price though you do need to wait til after delivery to claim your VAT back.
