My LEESA Down Alternative Duvet Insert is Goldilocks. It is not too heavy or lightweight but just right!

Duvet insert
Ok so I was looking for a thinner duvet insert,and I found it, this one is good by Leesa,it has a little not annoying noise as you sleep,as you turn,hopefully it goes away but if not I don’t mind,I love the ties by the corner so it can be secure without moving inside too much,I love the materials that’s breathable is a plus,I feel rested which is extremely important,thanks Leesa to make an amazing insert.
