How to Pack Bulky Items Like Coats and Bedding for Moving or Storage

Bulky soft items are the worst thing to move or store efficiently — a single comforter or puffer jacket can fill most of a moving box on its own, mostly with trapped air rather than actual material.

Why bulky items are hard to pack efficiently

Coats, comforters, pillows and winter bedding are lofted on purpose — the air trapped inside the fill is what makes them warm. That same air is what makes them take up so much space in a box or closet. Folding them tighter only helps a little, because folded fabric still holds onto most of its trapped air.

Compression is built for exactly this

Vacuum compression bags remove that trapped air directly, and bulky, air-heavy items are where they make the biggest visible difference — often shrinking down by up to 80% in volume. A single large or jumbo compression bag can hold a full comforter, several pillows, or multiple winter coats that would otherwise need a whole box each.

Packing for a move

• Compress out-of-season clothing and bedding first — anything you won't need to access during the move.
• Label compressed bags clearly, since a flattened bag looks different from its usual bulky shape and can be harder to identify at a glance.
• Stack compressed bags flat in boxes rather than standing them up, so they don't lose their seal under uneven weight.

Packing for seasonal storage

For off-season storage (winter coats in summer, summer bedding in winter), the airtight seal does double duty: it saves closet space and protects against moisture, dust and musty odors while the items sit unused for months. That's a meaningful difference from a regular storage box, which doesn't stop moisture or pests from getting in.

One thing to check first

Make sure everything is completely dry before sealing it — an airtight bag traps whatever moisture is already inside, which can cause mildew over a long storage period. Beyond that, bulky items are the single best use case for compression: it's where the space savings are the most dramatic and the most useful.
