Black Friday can be a good time to replace a child's mattress, move from a toddler bed to a Single or King Single, or buy the correct low-profile mattress for a bunk bed.

But when you're shopping for a Black Friday kids mattress, the safest starting point isn't the discount.

It's the bed your child sleeps on.

The Best in Beds Black Friday Sale runs from Sunday 1 November to Sunday 29 November 2026, with selected kids mattresses from Eco Kids, Boori and other ranges included in the campaign.

Which Kids Mattress Size Do You Need?

The most common starting points are:

• Single - approximately 92 × 188 cm. A practical choice for first beds and smaller bedrooms.
• King Single - approximately 107 × 203 cm. Wider and longer than a Single, making it popular for growing children and teenagers.
• Double - approximately 138 × 188 cm. Often chosen for older children, teenagers or parents who sometimes lie beside their child.

Before ordering, check the actual bed-frame dimensions and mattress requirements rather than assuming every children's bed takes the same mattress.

Black Friday Single Mattress Deals for Kids

Single is still one of the most common children's mattress sizes.

The current Black Friday range includes options from Eco Kids and Boori, along with selected other mattresses available in Single.

For younger children, consider support, breathability, edge stability and how the mattress feels when the child moves during the night.

Price matters, but children can spend many hours each night on their mattress, so we'd treat support and construction as part of the buying decision rather than buying on discount alone.

King Single Kids Mattresses on Black Friday

King Single is an increasingly popular long-term choice.

It gives a child more room than a Single and uses the same 203 cm length as Queen and King mattresses.

That extra length can make it particularly useful for growing kids and teenagers.

If you're replacing both the bed and mattress during Black Friday, check that the mattress size and frame size match before ordering.

What About a Mattress for the Top Bunk?

This is where mattress height becomes especially important.

A thicker mattress is not automatically better for a bunk bed.

The upper bunk must retain the effective height of its guardrail, so always follow the bed manufacturer's maximum mattress-height specification.

The Eco Kids Bunk Mattress is purpose-built as a low-profile option and is approximately 14.5 cm high.

That makes it useful for bunk beds and other applications where overall mattress depth matters.

Before buying any bunk mattress, confirm the exact mattress size and permitted height for your particular bunk.

Eco Kids Mattresses in the Black Friday Sale

The current Black Friday range includes selected Eco Kids products, including standard, Deluxe, Nature Luxe and low-profile bunk options.

These models suit different jobs rather than being interchangeable.

For example, a low-profile bunk mattress solves a different problem from a more generously cushioned mattress for a conventional bed.

You can browse the Eco Kids range or read our Eco Kids vs Boori Mattress Comparison for a more detailed comparison.

Boori Kids Mattresses

Boori also has Single, King Single and Double kids mattress options participating in the current Black Friday range.

For families already using Boori beds, this can make size matching straightforward.

As always, check the individual bed's required mattress dimensions before ordering - particularly with bunks, trundles, bedside beds and less common configurations.

Should Parents Consider a Double Bed?

Yes.

Parents often think kids bedrooms mean Single or King Single only, but Double beds are increasingly relevant for older children and teenagers.

They also provide extra room if a parent regularly reads, settles or occasionally sleeps beside their child.

If the bedroom has enough floor space, Black Friday can be an opportunity to compare the cost of moving directly to Double instead of replacing a smaller bed again later.

Where Can Sydney Parents Try Kids Mattresses?

Best in Beds has showrooms at Campbelltown and Prospect in Sydney, with Warrawong serving Wollongong and the Illawarra.

The advantage of visiting is that you can compare mattress feel, inspect beds and bunks and discuss the correct mattress dimensions before ordering.

Display stock varies, so contact the store if there is a particular kids mattress or bed you want to see.

Don't Forget the Bed Itself

The Black Friday range isn't limited to mattresses.

Selected kids beds, bunks, storage products and other bedroom furniture are also included.

If you're replacing an entire sleep setup, start with the bed configuration first and then choose the correct mattress.

That approach is especially important with bunk and loft beds because mattress dimensions and maximum height can form part of the bed's safety requirements.

Browse the Kids Bedroom collection to compare beds, bunks, mattresses and bedroom furniture.

Choosing a Kids Mattress During Black Friday

A Black Friday kids mattress should still be a mattress you'd be comfortable buying without the promotional label.

Start with:

• the correct size;
• the correct mattress height for the bed;
• appropriate support and comfort;
• the child's likely growth; and
• the amount of room available in the bedroom.

Then compare the current Black Friday price.
