Mattress Care
Mattress Care
- We think a mattress should always be used with a mattress protector.
- Any stains or marks on the mattress should be removed with careful wiping or dabbing with a damp cloth.
- Don’t use solvents or chemicals and don’t over wet.
- Allow the area to dry before covering again.
- You do not need to flip your Sleep Republic mattress. We have designed our mattress as a single sided pillow top with the best quality pocket spring core and pillow top contents.
- Rotating the mattress, top to bottom, monthly will keep it in top condition.

We're the real deal
We've been dreaming up new designs for mattresses for over 30 years. We've refined our mattress design by constantly experimenting and investigating new technologies and materials.

Frequently asked questions
Is Sleep Republic’s hybrid design better for kids than a cheaper foam mattress?
Is Sleep Republic’s hybrid design better for kids than a cheaper foam mattress?
We know it may seem tempting to purchase a cheaper foam mattress for kids; a child’s body doesn’t need proper spinal support, does it? Well, nothing could be further from the truth. The best child’s mattress will support their growing bodies to ensure healthy development. Good spinal support and zoned pressure relief will ensure optimum comfort without wriggling around all night to get comfortable. The hybrid design will also ensure that they won’t wake up hot through the night and the quality materials provide a lasting sleep surface they can grow with. Sleep Republic’s kid’s mattresses are also made with natural, high-quality materials, so they’re breathable, dust-free, eco-friendly, naturally hypoallergenic, and ideal for children with asthma or allergies. On the other hand, some full foam mattresses can be filled with nasty chemicals and toxins that can damage your child’s health or aggravate existing respiratory conditions. Premium edge support from the firmer springs around the perimeter also prevents edge sagging, so you won’t feel like you’re about to fall out of bed, even if you are seated during bedtime reading. A foam child’s mattress simply cannot compete with the innovative layers provided by our award-winning hybrid mattress design.
How do I unpack my Kids Mattress?
How do I unpack my Kids Mattress?
Your Welcome Pack with opening instructions and an opening ‘tool’ is included inside the mattress box. You can remove the blue outer wrapper with a pair of scissors that have a rounded point, so they don’t puncture the inner vacuum bag or damage the mattress . The mattress can then be unrolled just like a very large newspaper. NB exercise caution while unrolling as the mattress can unroll quickly if the inner vacuum bag has been punctured.
What is the 150-Night Free Trial?
What is the 150-Night Free Trial?
We understand that it may take some time to work out if our hybrid design is the best kids mattress for your child, so we give you up to 150 nights to decide. If you’re not completely satisfied or your child doesn’t feel it’s a good match for them, let us know within 150 nights of delivery, and we’ll arrange to collect it free of charge and refund the purchase cost. We always recommend trying the mattress for a minimum of 14 days because changing mattresses, even from a seriously bad one,takes time to adjust. However, if you’re certain the mattress isn’t the right feel for your child, that’s good enough for us! Please see the link to ourreturnspage for more details.
What base or bed frame can I use with a Sleep Republic Kids Mattress?
What base or bed frame can I use with a Sleep Republic Kids Mattress?
Choosing the right mattress base is important to ensure the longevity of our mattresses. Curved or flexible type slats and sprung bases are not suitable. The gaps between slats should not exceed 8 – 10cm. Wider gaps will not provide adequate support for the mattress. If you’re interested in purchasing a new base for your Sleep Republic children’s mattress, please consider our Pro Base, which provides the perfect foundation for all our kids' mattresses and comes in the same sizes as our mattress.
