Getting your bed ready for the chilly months ahead isn't difficult and it doesn't have to cost a fortune.

Let Layers Act as Insulation

$219 for queen,

An effective way to trap heat in your bed is to use multiple layers, rather than rely on just one big, fluffy duvet. Several layers create pockets of warm air, insulating your bed. For maximum warmth, top your duvet with a lightweight, yet cozy quilted blanket. Filled with down, this blanket is machine-washable, making it easy to keep clean. Plus, it comes in 12 different colors, so you can choose the hue that best matches your bedroom decor.

Upgrade Your Sheet Set

$119 for queen,

During the warmer months, cool linen or percale is the bed sheet of choice, but in the winter, it's all about flannel for a cozy bed. In general, flannel is thicker, heavier, and retains heat better than your summer linens, so you'll feel noticeable warmer all winter long.

Swap Out Your Duvet Insert

$269 for queen,

If you sleep soundly in the summer with the thinnest, airiest duvet imaginable, it's time to switch out the insert for something with a little more substance. When it comes to warmth that's still breathable (important for those who tend to sweat at night!), down or a down alternative is your best bet. For the warmest, yet most lightweight duvet, look for one labeled "all down" or "100% down." 

Check out the fill power: On the packaging of most down duvets, you'll notice a rating for "fill power," which is essentially a measurement of the down's fluffiness. For winter, you'll want one with a fill power of around 600 to 800.

Pile on the Throw Pillows


Adding lush throw pillows to your bed will not only make it look cozier, but it will also feel warmer—especially if you opt for velvet, faux fur, or knitted pillow covers. While you may not necessarily want to sleep with the pillow pile on your bed, it will make your bed feel snuggly while you read or watch TV.
