Mr Sleep Beds Waterproof – (Best Single)

Elegant Beds Waterproof Dual Sided Single Mattress for Kids & Adult

Everyone knows that accidents happen with kids, even well past years of being potty-trained. If you have a young child (or even an older one) that just needs that little bit of protection with a waterproof mattress.

Also, too many parents know that waterproof products feel like plastic when you lay on them. This product feels like a mattress and doesn’t give away the telltale crinkle of a plastic mattress.

It is important to notice that the waterproof feature of this mattress is on the top and the bottom, but the seams are not entirely waterproof. It can withstand accidents though. The company says the double sided mattress works for adults, but it is only three feet in width, so it might not suit large-bodied/overweight adults.

Don’t forget this 3 foot (the UK Single mattress width) is about 16.5 centimetres thick to suit beds like cots, trundles, and bunk beds. For children, it gets the job done!

Mr Sleep Beds makes sure the quality of the waterproof mattress meets all United Kingdom fire regulations, as is required for your child’s safety. When you need a quick delivery, it might make the perfect set for your family.

  • Keep your children comfortable
  • Minimises damage or odour caused by accidents your child has
  • Made to last even with use by a young child
  • Optimal thickness for low depth bed frames
  • Soft enough to sink into the mattress
  • Some users report the mattress as uncomfortable
  • Cannot tolerate a full soak of liquid

Types Of Kids Mattresses

Worried about figuring out the right kinds of coils for your child’s mattress? You will likely run across an innerspring mattress, either in an open or closed coil. An open coil innerspring mattress is suitable for families focused on pricing and does not wear out because of the weight of a young child. A pocket coil mattress may be more expensive but with coils wrapped in fabric, it contours your kid’s spine well.

Another option growing in popularity to consider for future purchases is a memory foam mattress. The polyurethane material in memory foam is sensitive to your temperature changes and keeps you fresh. It relieves pain from pressure points but tends to be quite expensive.

How To Choose A Mattress For Your Child

It is easy to get overwhelmed by the options in a home décor store. When you have too many options to choose from, narrow down the selection by considering essential factors.

  • Buy the correct size. Around the age of two or three, a child might transition from a cot bed mattress and into a child’s bed. This is a smaller size than a child has after the age of seven or eight years old.
  • Check out the materials used in the product. Especially in cases while your child has allergies, make sure the materials used in the construction of the mattress match your needs. Synthetic elements are not necessarily wrong to purchase, just be sure you know about their uses.
  • Focus on support for the spine. When your child is growing, they’ll need help for the spine. More than firmness or softness, ask about the springs used in your childs new mattress. Pocket coils work independently of one another and are more comfortable. (As a general rule, back and side sleepers do better on a firm bed).
  • Decide on durability. Accidents happen with kids, and no matter what they do, a kids mattress needs to stand up to a little jumping. For young toddlers, a waterproof cover may be necessary.
  • Build on a foundation. There are two general types of beds, those with wooden slats (a platform bed) or those that are box springs. In the majority of cases, toddler beds have foundational bed frames (platform) that do not need box springs. Save money with this choice!

What Level Of Firmness Does A Child Need?

What level of firmness for kids?

Kids mattresses tend to be less firm than others. When your child’s spine is growing, a bed needs to be comfortable but durable. Paediatricians recommend mattresses for children with firmness to encourage spinal alignment. A mattress with a strong core retains its shape and may even promote bone growth.

If your child is a one-side sleeper or sleeps on their back, then a soft mattress will likely be more comfortable. If your child sleeps on their stomach or moves around on their sides, a firmer mattress should be better for sleep. Remember, a firm mattress keeps the spine steadier at night.

Does Research Support A Good Mattress?

There are numerous scientific studies conducted concerning sleep, age, development, and other factors. The data indicates that children need the right amount of sleep for their health and development.

For example, research suggests less sleep is associated with a higher body mass index in children. Children who get more sleep have fewer risk factors for Type 2 Diabetes, and older children have a different natural sleep cycle than younger ones.

A low-quality cheap mattress without the support your child needs causes soreness, fatigue, and may not be able to focus on school because of exhaustion. Just like the story of Goldilocks and the three bears, you might need to try a few options before your child finds what is right!

Healthy Sleep For Growth and Development

The National Sleep Foundation says that the average preschooler (that falls between three to five years of age) needs no less than 10 to 13 hours of sleep while a school-age child up to 12 years old requires 9 to 11 hours a night!

Encourage healthy sleep for your child with a good mattress but also through the development of high sleep habits. Here are some of the basics to building an active pattern for better sleep with your little ones:

  • Maintain a regular sleep schedule
  • Schedule naps at the same time every day
  • Build a daily bedtime routine with your baby as they grow into toddler years
  • Keep your child in the same sleeping environment every night
  • Don’t allow your child to watch television or use any electronics before bedtime
  • As your kid grows up, keep the bedroom conducive to sleep
  • Drop the temperature of your home during the nighttime


After assessing all of the children’s mattresses on the market, it is apparent there are solutions available for many price points and purchase preferences. Mattresses for children are smaller in size than those for adults. Remember, your child will grow quickly and soon enough you’ll be upgrading it for length.

Silentnight Healthy GrowthOf the five options listed, our favourite recommendation for children is the Silentnight Extra Comfort kids mattress. We love the breathable airflow border that comes with it and the extra comfortable spring system they developed for spinal alignment. Anything explicitly designed for your child’s current life stage could make the difference between spinal issues and spinal alignment.

If you need the best mattress for kids, our first recommendation is the Silentnight Extra Comfort. However, any of the other four options on this list are also viable solutions for your child’s sound sleep!
