Quick answer: A washable sweater bed is an old jumper stuffed with a removable cushion. Sew or tie the neck closed, stuff the sleeves and curl them round into a bolster, then slip a pillow wrapped in a fabric remnant into the body. Choose a tight knit, trim every loose yarn end, and wash the cover weekly.
An old jumper has most of what a cat bed needs already: soft fabric, a body that forms a pocket, and two sleeves that can become a raised rim. With a few remnants and a spare cushion, it turns into a bed that costs almost nothing and comes apart for the washing machine.
This guide covers which sweaters work, how to make the bed with or without sewing, and the safety points that matter with knitted fabric. If you would rather start from scratch, our DIY cat beds and caves hub gathers other soft builds.
Choosing a Sweater and Remnants
The best sweaters for a bed are machine-washable, tightly knitted and plain. Fine cotton, acrylic and merino-blend knits hold their shape and shed little. Chunky, loosely knitted wool and anything with long fringes or pompoms is a poor choice, because loops catch claws and loose yarn can be pulled out.
Check the jumper for holes and worn cuffs. Small holes can be darned, but a jumper that is already unravelling will keep doing so once a cat kneads it. Remove any buttons, toggles, sequins or beads before you begin.
For the inner cushion, a small pillow, a folded towel or polyester wadding works. Wrap it in a remnant of cotton or fleece so the filling never touches the knit directly and the insert can be washed separately.
| Material | Works well | Skip it |
|---|---|---|
| Sweater | Tight cotton or acrylic knit | Chunky wool, open lace knits |
| Insert | Small pillow, folded towel | Loose beads, foam crumbs |
| Insert cover | Cotton or fleece remnant | Fabric with fringes or ties |
| Closures | Stitching, flat knots | Buttons, ribbons, drawstrings |
Making the Washable Sweater Bed
The basic shape is a cushion in the body with the sleeves wrapped around it. You can sew it in under an hour or make a no-sew version that relies on stuffing and a few flat knots.
- Turn the sweater inside out and stitch the neck opening closed with a straight seam, or gather it and tie it tightly with a flat knot inside.
- Turn it right side out again and stuff each sleeve firmly with wadding or rolled socks until it forms a soft tube.
- Stitch or tie the cuffs closed so no stuffing can escape.
- Draw a line across the chest from armpit to armpit and sew along it, creating a pocket in the lower body.
- Slide the wrapped cushion into the pocket through the waistband.
- Curve the sleeves around the front and stitch the cuffs together to form a ring-shaped bolster.
- Fold the waistband under and tack it so the cushion stays in but can be pulled out for washing.
For a no-sew version, skip the chest seam and pack the body with the wrapped cushion, then fold the sleeves round and tie the cuffs together with a short, flat knot tucked underneath where the cat cannot reach it.
Why the Insert Should Come Out
The removable cushion is what makes the bed practical. Stuffed sleeves can stay in place for most washes, but the main pad picks up hair and dander fastest. Pulling it out lets you wash the sweater shell gently and the insert cover more often.
Keep a second insert cover on hand so the bed never sits empty while one is drying. A quick swap each week keeps the bed fresh without much effort, and cats that like a familiar scent are less likely to abandon it.
If your cat tends to knead heavily, a fleece insert cover on top gives the claws something smoother to grip than the knit, which reduces snags in the sweater itself.
Loose Yarn, Thread and Other Safety Checks
Knitted fabric has one specific risk: loose ends. VCA Animal Hospitals notes that cats are notorious for ingesting thread, wool, paper, rubber bands, plant materials and small toys, and warns that swallowed thread or yarn can become a serious problem. A sweater bed should never have a yarn tail a cat can catch and pull.
- Trim all thread ends close to the knot after sewing
- Darn small holes before they spread
- Remove buttons, toggles and labels with hard edges
- Check cuffs and the neck seam weekly for unravelling
- Retire the bed if the knit starts to ladder or pull apart
- Keep spare wool and sewing thread away from the cat while you work
If you find chewed or missing yarn, take the bed away and watch for vomiting, a reduced appetite or straining. Contact your vet promptly if you think any thread has been swallowed.
Kneading, Claws and Older Cats
Many cats knead soft beds before settling, and a sweater invites it. That is normal behaviour, but claws can catch in the loops. International Cat Care notes that senior cats can struggle with retracting their claws, so they may get caught in furniture and carpets, which applies to knitted beds too.
For older cats, keep the front bolster low so it is easy to step over, and choose a tight knit that claws slide off rather than hook into. Regular claw checks help, and our guide to a safe heated bed cover for older cats explains how to add warmth without cords inside the bed.
If your cat kneads or scratches your own bedding instead, our article on why cats scratch the bed covers the reasons and a few simple redirections.
Washing Routine
Wash the insert cover weekly and the sweater shell every two to four weeks on a gentle cycle. Use an unscented detergent and skip strong fabric conditioners. Reshape the sleeves while damp and let everything dry fully before reassembling, since a damp bed in a cool room can smell musty.
If the sleeves lose their stuffing shape after a few washes, top them up through the cuff before stitching it again. A bed that goes flat is less inviting, and a quick refill keeps it usable for months.
Sizing It to Your Cat
Match the sweater to the cat rather than the other way round. A small adult curls comfortably inside a women's medium jumper, while a large cat or two cats that share usually need a men's large or extra large. Measure your cat curled up asleep from nose to the base of the tail and add a hand-width; that is roughly the inside diameter you want between the sleeves.
If the jumper is too big, fold the waistband under twice before stitching so the pocket is shallower. If it is too small, a sweater bed works better as a cushion than a nest, so drop the bolster and use it flat on a chair.
A bed is for sleeping, not scratching, so many owners place a scratch post nearby for the stretch that follows a nap. Our DIY cat scratcher hub covers simple builds that take that job away from the knit.
Choosing a Spot for the Sweater Bed
International Cat Care describes how cats value high places to sit and plenty of places to disappear from view. A sweater bed is a low option, so place it somewhere quiet but in sight of the room: beside a sofa, under a side table or in a corner away from doorways.
Avoid putting it right next to food bowls or the litter tray. For a cooler alternative in hot months, see our summer cooling bed project, and if cost is the main concern our roundup of a budget cat bed under 40 dollars lists other cheap options.
Sweater Bed FAQs
Can I make a sweater cat bed without sewing?
Yes. Tie the neck closed with a flat knot inside, stuff the sleeves firmly, slide a wrapped cushion into the body and tie the cuffs together underneath. It is less durable than a sewn version, so check the knots and stuffing each time you wash it, and retie anything that has worked loose before returning the bed.
What kind of sweater is safest for a cat bed?
A plain, tightly knitted, machine-washable sweater is safest. Fine cotton and acrylic knits shed little and resist snagging. Avoid chunky or open wool knits, fringes, pompoms, buttons and sequins. Darn small holes before you start, and do not use a jumper that is already unravelling, as loose yarn is a swallowing risk for cats.
How often should a sweater bed be washed?
Wash the removable insert cover about once a week and the sweater shell every two to four weeks, depending on shedding and accidents. Use a gentle cycle and unscented detergent, reshape the sleeves while damp, and let all parts dry completely before putting the bed back together so it does not develop a musty smell.
What should I do if my cat chews the sweater bed?
Remove the bed and check for missing yarn or thread. Watch your cat for vomiting, reduced appetite or straining, and call your vet if you suspect anything was swallowed. Before offering the bed again, trim loose ends, darn damaged areas, or switch to a smoother fabric cover that is harder to pull apart.
