Main Features of Nectar UK’s Kids Mattress
After research and review, our team agrees that the top features of this mattress are:
- Dual-side design for two sleeping experiences
- Ages 3-7 one side; ages 7 and up other side
- 7-zone springs unit features 504 coils
- Washable, quilted cooling cover

The five-layer mattress is a hybrid type; it has two kinds of foam and pocket springs. The mattress can work with the most common bed frames, as per Nectar UK’s website: box spring, divan base, platform, and traditional frame.

Mattress Firmness
There are two different firmness levels in this dual-sided mattress. That helps make it a good choice for many growing kids. Some reviewers describe the side for ages 3-7 as being firm, while the side for ages 7 and up is medium firm.
What about Size?
Nectar’s Kids Mattress comes in one size:
This size is standard for a single mattress in the UK. It is 16cm deep. While there is only one size available, the mattress is designed to be flipped; one side is made for kids ages 3-7, and ages 7 and up on the other side.
Nectar Kids Mattress Review of Construction
Here are the construction details for the Nectar 16cm-thick mattress to help you decide if it suits your child. The mattress is climate neutral, a label from ClimatePartner that refers to having a lower carbon footprint.
The soft quilted cover is the outermost layer on each side of the mattress. It has a cooling design for body temperature regulation. The cover is washable.
On the side designed for sleepers ages 3-7, a 2cm layer of conventional foam is directly beneath the cover. The purpose is for comfort and support. On the side designed for kids ages 7 and older, a dynamic memory foam support layer is directly beneath the cover. It is designed for additional support and to help with airflow.
Whichever side your child sleeps on, the third layer is the 7-zoned core. It is 12cm deep, featuring 504 pocket springs. These springs are individually wrapped in support foam for responsive comfort and great edge support to help prevent your child from falling out of bed. Good edge support also generally helps the mattress retain its shape over time.
Nectar UK Kids Mattress Review: Pros and Any Limitations
Knowing more about this child mattress can help you decide if it meets what you’re looking for and can accommodate your growing child.
Dual-Sided Design for Longer Use
Don’t let the one size available for Nectar’s Kids Mattress lead you to think that it’s only going to be useful for a few years. Instead, the single size mattress has a dual-sided design, so you can simply flip it when your child gets to a certain age.
Rather than having to get a whole new mattress when they outgrow the first side at age 7, flipping it over means they can get several more years out of it on the second side. Thus, it is like getting two mattresses in one.

Support and Comfort for a Growing Child
Nectar designs this mattress to provide the amount of support your child needs as they are developing. It is made to adapt to a child’s growing body.
One side, designed for kids between 3-7 years old, has a conventional foam layer, with the innerspring core below. This first side is designed to balance comfort and support for young children without them sinking into the mattress. Then, flip it over for kids ages 7 and up.
This second side features a comfy memory foam layer and innerspring core below that for a mix of comfort and support. As their strength has likely increased by age 7, they are typically able to move around on the memory foam to change sleep positions. Memory foam may provide pressure relief for growing kids, potentially helping keep the spine in a neutral position through the night.
However, there is only a single size available, which may not accommodate taller children. If your child outgrows the 190cm length of the mattress, they may need a European single size that has an extra 10cm more than single size. Many kids, though, fit a UK standard single size.
More about the Supportive Core
Regarding the 7-zoned support core, it is made to offer support where your child needs it the most. The 504 coils are individually wrapped to respond to weight differently.
That means they adjust to the natural curves of your child’s body, unlike a regular coil mattress, for greater contouring. Individually wrapped coil designs are known in the mattress industry for durability and support.

Safety Certification and Off-Gassing
The foam in Nectar’s Kids Mattress is CertiPUR® certified. That means it has met strict health and safety standards. The Fire Safety standard of Nectar mattresses, as per its site, is BS 7177 Domestic Use (low hazard).
However, as this mattress contains memory foam, there may be a faint smell or off-gassing upon opening the box it came in. Ventilating the bedroom can help, with the slight odour typically starting to fade after a few days, as per Nectar UK’s website.
Quilted Cover is Washable not Waterproof
The quilted mattress cover that comes with this mattress feels soft against your child’s body. That may help their body relax, which could lead to better sleep. While the cover is not waterproof, it is washable. That’s handy in case of an accident or spill.
For best care, clean the cover by hand with a light detergent and warm water, Nectar UK customer service explained to us by email, noting that using a washing machine may damage the material. While it would be easier to put in the washing machine, we understand the material is top quality and appreciate the gentle handwash to preserve it. If you are looking for a waterproof sleep surface for your kid, consider adding a mattress protector on top.
Cooling and Breathable Features
The mattress cover has a cooling design, drawing heat away from the body and circulating air as your child moves. That may help keep your little one from getting too hot during the night, which could be uncomfortable and lead to them waking up unexpectedly.
Also, the dynamic support layer is made to be breathable. This layer may help regulate body temperature, in addition to the support it offers, for a comfier sleep.
Also Important: Price, Warranty, and Sleep Trial
There are a few more things to consider when shopping for your child’s mattress.
Affordability
We consider the Kids Mattress from Nectar UK a reasonable price given it offers two sleep environments, depending on your child’s age, so it is meant to grow with your child. That means you get two mattresses for one, usable from age three through to over age 7.
The included mattress cover adds to the mattress value, as does the free shipping and returns in the UK Mainland. Old mattress removal is an available service for a small extra fee.
Sleep Trial
An impressive 365-night trial from Nectar UK comes with the Kids Mattress. That gives your child an entire year after the mattress is delivered to your home to decide if it offers the comfort and support they like. That gives confidence in the mattress; while unlikely to happen, if you want to return it for free within the allotted period you can (meeting the respective policy guidelines, of course).
Forever Warranty
Nectar UK includes a Limited Forever Warranty with the Kids Mattress, offering peace of mind with its lengthy protection for you as the original purchaser. The warranty covers defects in material and workmanship as outlined in the related policy. Readying the warranty policy helps you understand what it includes, excludes, and other important details.
Concluding the Nectar Kids Mattress Review
The Kids Mattress accommodates different developmental stages, with one side for ages 3-7, and the other side for ages 7 and up. That offers some families a mattress with longevity and durability, which is especially important for those on a budget. The long included warranty adds to the value, as does the sleep trial.
While there is not a waterproof cover, Nectar’s mattress offers a lot to make up for that. It has the potential to provide support, comfort, cooling, and breathability for children. We consider Nectar’s Kids Mattress a quality one for families to consider.
