Zipped Mattresses NZ: Your Most Frequently Asked Questions Answered

Zipped mattresses are becoming an increasingly interesting option for New Zealanders looking for a little more flexibility from their bed.

Perhaps you're wondering whether you'll feel the join down the middle. Maybe you want a Super King mattress but have a tricky staircase. Or perhaps you've seen two mattresses joined together in a hotel and wondered how they actually work.

Whatever brought you here, we've put together answers to some of the most common questions about zipped mattresses.

No complicated mattress terminology. Just practical advice to help you decide whether a zipped bed is right for you.

1. What exactly is a zipped mattress?

A zipped mattress is made from two separate mattress sections that can be connected using a zip to create one larger sleeping surface.

At Luxury Orthopaedic Beds, our zipped mattresses feature a concealed joining zip, allowing the sections to sit together while maintaining the appearance of one larger bed.

Unlike simply pushing two ordinary mattresses together, a purpose-built zipped mattress has a joining mechanism designed for the job.

2. Can you feel the zip when you're sleeping?

This is probably one of the first things people wonder about.

The zip itself is concealed, so it isn't designed to sit exposed on the sleeping surface.

However, because a zipped mattress consists of two separate sections, there is still a physical join between them.

How noticeable that join feels depends on the mattress construction, how the sections are aligned and where you lie.

If you regularly sleep right across the middle of your bed, it's worth considering this before choosing a zipped configuration.

A zipped mattress can offer excellent convenience, but we wouldn't claim that its centre feels identical to a completely uninterrupted one-piece mattress.

3. Do zipped mattresses separate during the night?

A properly connected zipped mattress is designed to keep its two sections joined together.

That's one of the main differences between a purpose-made zipped mattress and two unrelated mattresses pushed side by side.

However, the bed base also matters.

If two separate bases aren't correctly positioned or secured, they can contribute to unwanted movement.

For the best result, both mattress sections should sit on a stable, compatible base.

4. Is a zipped mattress less comfortable than a normal mattress?

Not necessarily.

A zipped mattress can contain the same general types of support and comfort materials as a conventional mattress.

What changes is the way the sleeping surface is constructed.

Our Orthopaedic Merino Mattress features our own technically designed Orthopaedic 5-Zone Pocket Spring System, with specifications covering spring gauge, coil characteristics, coil count and the arrangement of the five support zones.

This design is intended to provide different support responses across the body, rather than relying simply on a generic five-zone spring unit.

Our mattress also incorporates cushioning layers, a New Zealand merino wool comfort topper and foam-encased edge support.

With a zipped configuration, there is an additional consideration: how the two sections meet in the middle.

For some customers, the practicality of having two manageable mattress sections is well worth it. Others may prefer the uninterrupted surface of a conventional mattress.

Neither option is automatically better for everyone.

5. Can you get a zipped King, Super King or California King mattress in NZ?

Yes.

Luxury Orthopaedic Beds offers zipped mattress configurations in:

King — 1670 × 2030mm

Super King — 1820 × 2030mm

California King — 2030 × 2030mm

These are the overall mattress dimensions when the sections are joined.

Before purchasing, make sure you also confirm the dimensions of the individual mattress sections, particularly if access through stairs, doorways or hallways is a concern.

6. Can you buy a zipped mattress without buying a new bed base?

Yes, provided your existing base is suitable.

However, it's important to check compatibility before ordering.

A zipped mattress requires suitable underlying support, just like a conventional mattress.

If your existing base is uneven, worn or not correctly sized, it may affect how the mattress sections sit together.

And if you're planning to use the mattresses separately, you'll need to consider whether your base configuration supports that arrangement.

7. Is a split bed base the same as a zipped mattress?

No, and this is an important distinction.

A split base means the bed base itself is manufactured in separate sections.

A zipped mattress means the mattress is manufactured in separate sections that connect with a zip.

You can have a one-piece mattress sitting on a two-piece base.

In fact, at Luxury Orthopaedic Beds, our King, Super King and California King upholstered bases are normally supplied in two sections.

Choosing a zipped mattress is a separate decision.

8. Can you use ordinary sheets on a zipped mattress?

Generally, yes.

When the two mattress sections are joined to form one complete bed, you can normally use fitted sheets and bedding sized for the combined mattress dimensions.

For example, a zipped Super King mattress can be dressed using suitably sized Super King bedding.

Check the fitted sheet's pocket depth as well as its length and width.

If you're planning to separate the sections into individual beds, you'll need bedding that fits each section independently.

9. Do you need two mattress protectors?

Not necessarily.

If you intend to keep your zipped mattress joined together, a suitably sized protector can cover the complete mattress.

If you regularly separate the mattresses, individual protectors may be more practical.

The right choice depends on how you'll use the bed.

If you're purchasing from Luxury Orthopaedic Beds and wish to qualify for our 60-Night Comfort Guarantee, remember that the required Protect-A-Bed mattress protector must be purchased from us on the same invoice. Other eligibility conditions also apply.

10. Can you rotate a zipped mattress?

Yes, but always follow the care instructions provided with your particular mattress.

For our Orthopaedic Merino Mattresses, we recommend regular rotation to help distribute use.

Our standard care guidance is to rotate the mattress every two weeks for the first three months, followed by approximately every one to two months.

For zipped mattresses, take particular care with the joining zip and ensure each section is correctly positioned and compatible with the intended rotation.

Never force a mattress section into a configuration that doesn't align properly.

11. Are zipped mattresses easier to move house with?

They can be considerably more manageable.

Anyone who has tried manoeuvring a large mattress around a tight staircase will understand why.

A zipped mattress allows the two sections to be moved individually instead of handling one very large mattress.

This can be especially useful for:

Upstairs bedrooms.

Apartments and townhouses.

Homes with narrow hallways.

Properties with tight staircase turns.

People who expect to move in the future.

However, it's still important to measure carefully.

Two smaller mattress sections can be easier to handle, but that doesn't guarantee they'll fit through every doorway or staircase.

12. Can you use a zipped mattress with an upholstered headboard?

Yes.

A zipped mattress can be paired with an appropriately sized upholstered base and headboard.

The important consideration is whether you're planning to keep the bed joined or regularly separate it.

If the bed will remain in one large configuration, a single headboard may be suitable.

If you want two independently functioning beds, separate headboards and compatible fittings may be more practical.

For custom configurations, confirm the number of headboards, their dimensions and the placement of mounting brackets before manufacture.

13. Can you have different firmness levels on each side?

Some zipped mattress systems are designed to accommodate different comfort levels.

However, this varies between manufacturers.

At Luxury Orthopaedic Beds, both halves of our current zipped Orthopaedic Merino Mattress must be manufactured in the same comfort level.

You can choose from our available Soft, Medium, Firm and Extra Firm comfort options, subject to the applicable product configuration.

If you're specifically looking for a mattress with two different comfort levels, it's important to check whether the manufacturer offers that construction rather than assuming every zipped mattress works that way.

14. Do zipped mattresses cost more?

They often do, because manufacturing two separate sections and incorporating a joining mechanism can involve additional work.

At Luxury Orthopaedic Beds, our zipped mattress option has an additional charge compared with the equivalent standard mattress.

Whether the extra cost is worthwhile depends on why you're considering one.

If you're buying a zipped mattress because it will make access to an upstairs bedroom much easier, the additional cost may be a sensible investment.

If you never intend to separate your mattress and your home has straightforward access, a conventional one-piece mattress may be the simpler option.

15. Are zipped mattresses good for everyday sleeping?

Absolutely, provided the mattress construction, comfort level and overall configuration suit your needs.

Zipped mattresses aren't exclusively designed for hotels or occasional guest use.

They can be a practical everyday option for people who want a larger mattress in a format that's easier to handle.

What matters most is selecting the right mattress for your body and deciding whether the centre join and split construction suit the way you sleep.

16. Where can I buy a zipped mattress in New Zealand?

So, Is a Zipped Mattress Right for You?

A zipped mattress isn't something everybody needs.

But for the right home and the right situation, it can be an extremely practical option.

It gives you the generous sleeping space of a larger mattress, with the convenience of being able to handle the individual sections when required.

The most important thing is knowing what you're buying, how it works and whether it suits your sleeping preferences.

And now, hopefully, you have a much clearer idea.
