Best Hypoallergenic Mattresses for Kids with Asthma and Allergies
Hypoallergenic mattresses for kids are designed with materials that resist dust mites, mould and bacteria, helping to reduce night-time triggers for children with asthma or allergies. By choosing the right type and size you can create a cleaner sleep surface that supports easier breathing without sacrificing support or durability.
What Makes a Mattress Hypoallergenic for Children?
A truly hypoallergenic mattress uses covers and fillings that discourage allergen build-up. Look for breathable natural fibres, waterproof barriers that are still vapour-permeable, and foams or springs treated to inhibit bacteria. UK law requires all mattresses to meet BS 7177 fire safety, so any product sold here has passed those tests while still offering allergy-friendly properties.
Key decision rule: if your child has confirmed dust-mite allergy, prioritise mattresses with removable, washable covers at 60 °C. For asthma, choose options with good airflow to keep the sleep surface cooler and drier.
UK Kids Mattress Sizes – Getting the Measurements Right
Use these exact UK sizes when choosing a hypoallergenic mattress for kids:
- Small single: 75x190 cm (2ft6)
- Single: 90x190 cm (3ft)
- Small double: 120x190 cm (4ft)
Cot mattresses are typically 60x120 cm; cot bed / toddler mattresses measure 70x140 cm. Always measure your child’s bed frame internally before buying – a 2 cm gap all round is ideal for safety and fit. EU sizes such as 90x200 cm will not fit standard UK single beds.
Material Choices That Reduce Dust Mites and Improve Breathing
Memory foam can trap heat, so it is better reserved for older children who do not overheat. Open-coil or pocket-sprung constructions allow more airflow. Natural latex and bamboo covers are naturally resistant to mites; waterproof eco-foam options add an extra hygiene layer without plastic feel.
Checklist before purchase:
- Confirm the cover can be removed and washed at 60 °C
- Choose breathable fillings – avoid thick non-ventilated foam layers
- Match firmness to your child’s weight – medium feel usually works for ages 3–12
- Check maximum mattress depth stated by the bed maker if using bunk beds (top-bunk guard rail must rise at least 16 cm above the mattress; BS EN 747 compliant bunk beds only; not recommended for children under 6)
For younger children, start with a cot mattress or toddler mattress that meets the same hypoallergenic criteria.
Recommended Hypoallergenic Kids Mattress Types
Kids pocket sprung mattresses offer individual springs that isolate movement and promote airflow, reducing moisture that dust mites need. Pair them with a washable cover for best results.
Kids memory foam mattresses provide pressure relief but can sleep warmer; select models with open-cell foam and a bamboo or anti-allergy outer layer.
Open-coil designs are lighter and cheaper but less supportive for growing spines; they still work if the cover is hypoallergenic and washable.

Pairing the Mattress with the Right Bed Frame
A slatted base with gaps no wider than 7 cm improves ventilation under the mattress. Wooden children’s beds or storage beds with drawers can work well, but ensure the slats are even and strong. For small rooms, a kids bed with integrated storage keeps clutter (and therefore dust) off the floor. White or grey finishes are easy to wipe clean. Always follow the bed manufacturer’s maximum mattress depth to keep bunk-bed guard rails effective.
Maintenance Checklist to Keep the Mattress Hypoallergenic
1. Vacuum the mattress surface monthly using the upholstery tool.
2. Wash removable covers every 4–6 weeks at 60 °C.
3. Use a separate washable mattress protector that is also mite-proof.
4. Air the room daily and keep humidity below 50 % with a dehumidifier if needed.
5. Rotate or flip the mattress as recommended to prevent body impressions that trap dust.
Following this routine extends the life of any hypoallergenic mattress and maintains its effectiveness against allergens.
When to Replace a Child’s Mattress
Replace when the mattress shows sagging greater than 2 cm, permanent odour that washing does not remove, or when your child has outgrown the size. Most quality kids mattresses last 5–7 years with proper care. Moving from a cot (60x120 cm) to a toddler bed (70x140 cm) then to a standard single (90x190 cm) is the usual progression.

Frequently asked questions
Are memory foam mattresses suitable for children with asthma?
Some kids memory foam mattresses are suitable if they have open-cell foam and a breathable, washable cover. They reduce pressure points but can retain more heat than sprung designs. Check the product page for ventilation details and choose a medium feel for growing children. A separate mite-proof protector adds extra protection.
What is the best size hypoallergenic mattress for a 5-year-old?
A standard single 90x190 cm (3ft) mattress is usually best for a 5-year-old. It allows room to grow and fits most UK single bed frames. For smaller rooms or bunk beds, confirm the frame states a maximum mattress depth so the guard rail still rises the required 16 cm above the surface.
Do I need a separate mattress protector with a hypoallergenic mattress?
Yes. Even mattresses with built-in waterproof barriers benefit from an additional washable protector. It provides a first line of defence against spills and makes cleaning easier. Choose one labelled mite-proof and machine-washable at 60 °C to maintain the hypoallergenic environment.
Can hypoallergenic mattresses be used in bunk beds?
Yes, provided the bunk bed meets BS EN 747 and the top-bunk guard rail rises at least 16 cm above the mattress. Use the maximum depth stated by the bed maker. Pocket-sprung or open-coil designs with good airflow are preferable to thick memory foam in top bunks to reduce trapped heat and moisture.
How often should I wash the cover of a kids hypoallergenic mattress?
Wash removable covers every 4–6 weeks at 60 °C to kill dust mites. Vacuum the surface monthly and air the mattress regularly. Consistent cleaning prevents allergen build-up and helps children with asthma or allergies breathe more easily at night.
