We recently switched to adjustable twin beds and needed to replace our 10 year old King duvet. I did my due diligence and settled on the twin classic duvets from Casper. We are delighted with the loft and warmth. I would recommend purchasing duvet covers first before the duvet comes from Casper. They ship fast and you’ll want to put the cover on as soon as possible to prevent coffee spills and dog prints getting on the satin soft duvet material.
