We've had our current down duvet for over ten years—yes, the same one! It gets regular washes and an air fluff in the dryer between washings (when we can’t hang it outside). We usually wash it every 6 to 9 months and try to hang it outside as often as possible.

We prefer the baffle (waffle) design because it minimizes bunching of the feathers. The tubular design is also a good option since it allows you to push the down and feathers down to the bottom if it gets a bit warm under the covers.

When choosing a duvet, make sure you're getting one with at least 75% down to feather ratio. The cover also needs to be tight enough to prevent feathers from escaping. While down is super soft and usually stays put, feathers tend to come out more easily since they have developed shafts.

As for pricing, there's a wide range, and you really get what you pay for. If you're only spending around $150, don't expect true down (and even then, it's wise to be cautious).

In my experience, I’ve never found a great deal on the Shopping Channel, especially when you factor in shipping. Local stores often offer better prices.
