The bedding a baby needs depends on age. Under 12 months: a firm flat mattress, a fitted sheet (sized for your specific cot: 140x70cm standard or 119x65cm compact), and a BS EN 16781:2019 sleeping bag. No duvets, quilts, pillows, or bumpers. From 12 months: a toddler duvet can be introduced.
From school age, children move to a UK single bed with a 90x190cm mattress. Fitted sheets, protectors and sleeping bags for every stage are in the Boori bedding collection, and Boori UK is an online-only store with free delivery to mainland UK.
Good sleep starts with comfort and hygiene. For children, bedding plays a bigger role than we often realise. It supports growing bodies, helps regulate temperature, and creates a clean, calming space that encourages rest. Choosing the right boori kids bedding is not about filling a room with extras. It is about picking pieces that feel soft, fit well, and are easy to care for through everyday life.
In UK homes, children's bedrooms often serve more than one purpose. A cot becomes a toddler bed. A small room becomes a shared space. Bedding needs to adapt without fuss. Boori's bedding range focuses on practical comfort, simple materials, and designs that work quietly in the background. With the right choices, bedtime feels predictable, clean, and relaxed.
What Bedding Does a Baby Need Under 12 Months?
A baby under 12 months needs only a fitted sheet on a firm, flat mattress and a baby sleeping bag, according to The Lullaby Trust.
The Lullaby Trust advises against duvets, quilts, bumpers, pillows and positioners for babies under 12 months, because they increase the risk of overheating and face covering. Keep the nursery at 16–20°C, place your baby on their back to sleep, and use the sleeping bag as the only warm layer.
Boori baby sleeping bags comply with BS EN 16781:2019, the UK safety standard for infant sleeping bags. Check the product label for the tog rating and minimum weight, sleeping bags must not be used with babies below the stated minimum weight.
For a safe sleep space from day one, start with a cot from the cots and cot beds range, then add a fitted sheet and sleeping bag sized for that model.
When Can a Child Have a Duvet?
A child can have a lightweight toddler duvet from 12 months, and a lightweight adult duvet from age 2.
The Lullaby Trust advises that duvets are not appropriate for babies under 12 months. From 12 months, a lightweight toddler duvet (4 tog) can be introduced. Full adult duvets are not appropriate until age 2+.
Never use a heavy adult duvet for a young child.
What Is the Best Mattress Protector for a Cot or Kids Bed?
The best mattress protector for a cot or kids bed is a waterproof one sized to the mattress, used under every fitted sheet.
Use a waterproof mattress protector under every fitted sheet. Keep 2 protectors in rotation. Machine washable at 60°C recommended for hygiene. Replace when the waterproof membrane shows signs of failure (water no longer beads on the surface).
Protectors come in cot and bed sizes: 140x70cm for a standard UK cot bed, 119x65cm for the Boori compact cot and 90x190cm for a UK single bed. Cot protectors and sleeping bags are also listed in the Accessories for Cots & Cot Beds collection.
A boori mattress protector is one of the most useful bedding items in a child's room. It sits between the mattress and the fitted sheet, quietly doing its job without changing how the bed feels.
Most mattress protectors focus on three main needs:
- Protection: They help shield the mattress from spills, sweat, and everyday moisture.
- Breathability: Airflow is important so children do not overheat during sleep.
- Ease of care: Protectors should be simple to remove and wash as part of a normal routine.
In busy households, having more than one protector can help. One can be on the bed while another is in the wash, keeping bedtime routines smooth.
For families browsing the full range of bedding options, the main Bedding collection brings together mattress protectors and fitted sheets designed to work together.
What Bedding Do Kids and Cots Need at Each Age?
Kids and cots need different bedding at each age: a fitted sheet and sleeping bag under 12 months, a toddler duvet from 12 months and a full UK single bedding set from school age.
Bedding by age, complete UK guide:
| Age Stage | Bedding Required | What to Avoid | UK Size |
|---|---|---|---|
| Newborn to 12 months | Fitted sheet + sleeping bag (BS EN 16781:2019) | No duvets, quilts, bumpers, pillows, positioners | Cot: 140x70cm or 119x65cm |
| 12–24 months | Fitted sheet + lightweight toddler duvet (4 tog) | No heavy adult duvets; no pillows until 2+ | Cot bed: 140x70cm |
| 2–5 years | Fitted sheet + duvet (4.5–7.5 tog for UK climate) | No oversized duvets that trap heat | Cot bed to single transition: 140x70cm → 90x190cm |
| 5–11 years (primary school) | Full UK single bedding set, fitted sheet + duvet + pillowcase | N/A | UK single: 90x190cm |
| 11+ years (secondary school) | UK single or double bedding set | N/A | UK single: 90x190cm; UK double: 135x190cm |
Children's bedding needs change with age. What works for a newborn is different from what suits a school-age child. Boori's range is designed to cover each stage without overwhelming the room.
Cot and Early Sleep Stages
For babies and toddlers, boori cot bedding focuses on simple, breathable layers that fit snugly and safely. Fitted sheets and protectors are designed to stay in place, supporting safe sleep routines.
Cot bedding works best when matched to the cot size and mattress depth. Families using convertible sleep furniture often find it helpful to plan bedding that can transition smoothly as the cot changes. If you are setting up a cot that will later convert, exploring options alongside Convertible Cots can help you plan bedding that lasts through more than one stage.
Compact spaces are also common in UK homes. For smaller nurseries, boori nursery bedding designed for compact sleep setups offers the same comfort in a scaled-down fit. These options work well with furniture from the Compact Cot range, keeping the room open and uncluttered.
Bedding for Growing Kids
As children grow, bedding becomes part of their personal space. Patterns, textures, and colours start to matter more. At the same time, parents still need practical fabrics that wash well and hold their shape.
Boori kids bedding for older children often includes fitted sheets, quilt covers, and protectors made from soft cotton materials. These are easy to layer and simple to change, which helps maintain routines on busy school mornings.
Many families also combine bedding with other boori kids bed accessories, such as mattress protectors or additional fitted sheets, to make laundry days easier. Having a spare set on hand means bedtime stays calm even when accidents or spills happen.
What Size Bedding Fits a UK Cot or Cot Bed?
A standard UK cot bed takes bedding sized 140x70cm, and the Boori compact cot takes bedding sized 119x65cm.
Cot bed fitted sheets and mattress protectors are sized to fit specific cot models. Standard UK cot bed: 140x70cm. Boori compact cot: 119x65cm. Always order the bedding sized for your specific cot, wrong-sized bedding is a safety risk.
A sheet that is too big will not lie flat, and loose fabric is a risk in a baby's sleep space. If you own a cot from the convertible cots range, the same 140x70cm bedding usually carries on into the toddler bed stage, because the mattress stays in place.
Compact cots need their own bedding. A standard cot bed sheet will not fit a 119x65cm mattress, so check the product page in the compact cot range.
What Size Bedding Fits a UK Single Kids Bed?
A UK single kids bed takes bedding sized 90x190cm.
From school age, children move to a UK single bed with a 90x190cm mattress. Fitted sheets, mattress protectors, and duvets must be sized for the UK single, European and US single sizes differ.
When your child moves from a cot bed to a single bed, all the bedding needs replacing, because cot bed sheets will not fit. Check the mattress size for your frame in the kids beds range before ordering, and keep 3 fitted sheets and 2 protectors in rotation.
What Tog Sleeping Bag or Duvet Does a Child Need in the UK?
The tog a child needs in the UK depends on the room temperature: a lighter tog in summer and a heavier tog in winter, for both baby sleeping bags and children's duvets.
Tog guide for UK climate:
| UK Room Temperature | Season | Recommended Sleeping Bag / Duvet Tog |
|---|---|---|
| Above 24°C | Summer | 0.5–1 tog sleeping bag (baby); 4.5 tog duvet (child) |
| 16–20°C | Spring / Autumn | 2.5 tog sleeping bag (baby); 7.5–10.5 tog duvet (child) |
| Below 16°C | Winter | 3.5 tog sleeping bag (baby); 10.5–13.5 tog duvet (child) |
| Target room temperature | All year | 16–20°C (Lullaby Trust recommendation for under-12 months) |
For babies, all Boori sleeping bags comply with BS EN 16781:2019. Use a room thermometer, and change the tog rather than adding blankets. For full UK safe sleep guidance, visit lullabytrust.org.uk.
How Does Bedding Support Comfort and Hygiene?
Clean bedding supports better sleep. Regular washing removes dust, allergens, and everyday dirt that builds up over time. Using the right layers makes this process easier.
A mattress protector acts as the first line of defence. It absorbs moisture and prevents stains from reaching the mattress. Sheets and covers can then be washed more frequently without worrying about deeper damage.
Choosing boori kids bedding made from breathable materials also helps regulate body temperature. This is especially useful for children who sleep warm or during seasonal changes. A comfortable temperature reduces night waking and supports longer, more settled sleep.
How Do I Clean and Maintain Kids Bedding?
Good care habits extend the life of bedding and keep it feeling fresh. Start by checking care labels before washing. Most bedding should be washed on a gentle cycle using mild detergent.
Wash sheets and pillowcases regularly, especially during warmer months or when children are unwell. Mattress protectors should also be washed often, particularly after spills or accidents. Avoid harsh chemicals or fabric softeners, as these can reduce breathability over time.
Dry bedding thoroughly before use. Damp fabrics can feel uncomfortable and may affect sleep quality. Rotating between two sets of boori kids bedding can help reduce wear and make washing schedules easier to manage.
How Do I Create a Calm Sleep Environment?
Bedding works best as part of a calm overall setup. Clear walkways, soft lighting, and uncluttered surfaces all support better sleep.
In warmer months, breathable bedding helps regulate temperature. In cooler seasons, layering with lightweight blankets can add warmth without heaviness.
Keeping designs simple helps children relax. Busy patterns may be fun during the day, but calmer tones often support better rest at night. This balance is central to boori kids bedding, which aims to support both comfort and everyday living.
How Do I Choose Bedding That Grows with My Child?
Children's needs change quickly. Bedding that works across stages saves time and cost. Neutral colours and simple designs often last longer visually, even as tastes change.
When moving from cot to bed, check mattress sizes carefully. A protector or fitted sheet designed for a cot may not suit a toddler bed or single bed. Planning ahead helps avoid last-minute replacements.
Many families find it helpful to build a small bedding set for each stage. For example, one protector and two fitted sheets for everyday use, plus seasonal layers as needed. This approach keeps sleep setups consistent while allowing flexibility.
How Does Bedding Fit into Everyday Routines?
Bedding plays a quiet role in daily routines. Making the bed in the morning, choosing sheets, or helping with laundry all teach children simple responsibility. Bedding that is easy to handle supports these small habits.
Lightweight fabrics are easier for children to help fold or place on the bed. Simple fastenings and fitted edges reduce frustration. Over time, these small details help children feel more comfortable managing their own space.
Pairing bedding choices with a tidy room layout also helps. Keeping spare bedding nearby and organised makes changes quick and stress-free, especially during busy weeks.
Frequently Asked Questions
What bedding does a baby need under 12 months in the UK?
Under 12 months, The Lullaby Trust (lullabytrust.org.uk) recommends a fitted sheet only on a firm, flat cot mattress, with a baby sleeping bag as the warm alternative to loose blankets. Nothing else should be in the cot sleep space, no duvets, quilts, bumpers, pillows, or positioners. Sleeping bags must comply with BS EN 16781:2019 and be tog-rated for the room temperature. The Boori cot bed fitted sheet size is 140x70cm; the compact cot fitted sheet is 119x65cm.
When can a baby have a duvet in the UK?
The Lullaby Trust advises that duvets are not appropriate for babies under 12 months due to overheating and suffocation risk. From 12 months, a lightweight toddler duvet of around 4 tog can be introduced. A standard adult duvet is not appropriate until age 2 and above, and a heavy duvet should not be used for children under 5. For school-age children in a UK single bed (90x190cm), a 7.5–10.5 tog duvet is appropriate for UK spring and autumn room temperatures.
What size bedding fits a Boori cot bed?
The standard Boori cot bed uses a 140x70cm mattress, fitted sheets, mattress protectors, and sleeping bags should be sized to match. The Boori compact cot uses a 119x65cm mattress, bedding must be ordered specifically for this size. Never use bedding sized for a different cot model: a loose fitted sheet is a safety risk. When transitioning from a cot bed to a UK single bed (90x190cm), all bedding must be replaced, cot bed bedding will not fit a standard UK single.
What tog sleeping bag does a UK baby need in winter?
In the UK, a 3.5 tog sleeping bag is appropriate for winter room temperatures below 16°C. For spring and autumn (room temperature 16–20°C), a 2.5 tog sleeping bag is appropriate. For summer (above 24°C), use a 0.5 or 1 tog bag. All Boori baby sleeping bags comply with BS EN 16781:2019. The Lullaby Trust recommends keeping the nursery at 16–20°C year-round, adjust clothing layers rather than tog rating when the temperature is within this range.
How do I use a mattress protector for a baby cot?
Place a waterproof mattress protector directly on the cot mattress, under the fitted sheet. The protector must be sized for your specific cot, 140x70cm for a standard UK cot bed, 119x65cm for a Boori compact cot. Keep two protectors in rotation so the bed can be remade immediately after a nighttime leak without waiting for laundry. Machine wash at 60°C for hygiene. Replace the protector when the waterproof membrane fails, when water no longer beads on the surface, the protection is compromised.
