Mattress delivered quickly and taken to my room as I asked. Delivery drivers missed the old one being taken away but checked paperwork and grabbed it.Website was decent, prices were fair and beat the competition (recycling and delivery were over 30 cheaper) and their range was great

Which mattress will be best for my children?

Available in all firmness levels, our children's mattresses can be tailored to the specific requirements of your child. Sleep is very important to a child’s development, and as such it’s crucial they receive the right amount of comfort and support. With children’s mattresses from leading brands such as Silentnight on offer, our selection of high value kids bed mattresses will help your little ones get a great night’s sleep. 

Should a mattress for kids be firm or soft?

Striking a balance between kids’ mattress firmness ratings depends on the sleeping preferences of the individual. Choosing a mattress with a softer feel is better suited to older kids or children who sleep on their side or back.

The stability of a firm mattress is ideal for front sleepers and younger children who require additional support, promoting a healthy spinal alignment. Kids mattresses at all ends of the firmness scale can be purchased from MattressNextDay.

What sizes are available for kid's mattresses?

What type of kids’ mattress is best for a child?

As with adult mattresses, there are an array of options available for kids. Our extensive range has been curated to help you find a kid’s mattress which matches your child’s specific requirements.

Pocket Sprung

Kids pocket sprung mattresses are designed with cloth-wrapped springs which offer support while responding to your child’s movements and weight.

Memory Foam

Suitable for a restless child, a memory foam mattress promotes a consistent sleeping position by conforming to their body shape. Children have greater difficulty regulating their body temperature at night, and as memory foam can feel warmer, you may want to pick one that has Coolgel properties or is designed specifically for kids and has better airflow qualities.  

One of the big benefits of memory foam is that it is hypoallergenic, so it’s perfect for young children who may suffer from sensitive skin, allergies, or asthma. Memory foam is also durable and long-lasting. To protect the surface, you can add a waterproof mattress protector which can be easily cleaned in the event of any little night-time accidents. 

Latex

These natural kid’s mattresses are breathable, making them adept at encouraging a consistent airflow as your child sleeps. Latex mattresses are suited to children who get hot at night. The luxurious finish of the smooth latex is designed to improve comfort.

Waterproof

Kids waterproof mattresses feature a tough top layer which won’t become damaged by moisture. A suitable mattress to protect against bedwetting, the waterproof surface will also effectively deal with spills of any kind.

Our child mattresses each have a minimum guarantee of 12 months. Select models are further protected by an additional 5-year warranty for additional assurance of quality. Depending on stock, our child mattresses can be with you in as little as 24 hours thanks to our nationwide next day delivery service. 

Are children’s mattresses anti-allergy?

Kids are susceptible to allergy-related irritations and bed bugs. This can be disruptive to their quality of sleep and the hygiene of their sleeping environment. A large percentage of our kid’s mattress range have hypoallergenic properties, helping young sufferers of asthma and other allergies to get to sleep. Opt for memory foam, latex, or natural fillings if you require an anti-allergy child’s mattress.

Should you add a kids mattress protector?

Taking care of your kid’s mattress is important to making the most of its lifespan. Designed to shield against bedwetting or spills, mattress protectors help defend against damage and wear and tear associated with moisture. Each mattress protector is easy to wash and comfortable, keeping the mattress fresh and dry.
