Frequently asked
Is this mattress hypoallergenic or dust mite resistant?
All mattresses gradually collect allergens through normal use. A mattress encasement can help create a barrier between you and the mattress surface.
- Encase the whole bed — mattress, pillows and quilt — for full coverage where you sleep. Shop the dust mite encasement range.
- Short on budget? Start with the mattress. A dust mite mattress protector covers the biggest surface for the lowest spend — then add a pillow protector and quilt protector later.
- Backed by research. A 2003 clinical trial found mattress and pillow encasings significantly reduced dust mite allergen levels over 12 months.
- Get the full setup right. Our low-allergen bedroom guide covers encasements, washing and humidity in one place.

What's a Bonnell spring mattress?
Bonnell springs are interconnected hourglass-shaped coils — a traditional, durable construction that gives a firmer, more supportive feel. They differ from pocket springs (individually wrapped, independent coils) in that the springs work as a single connected unit. The Alzbeta Series uses a Bonnell spring core.
How does 7.0 firmness compare?
On a 1-10 scale, 7.0 is a firmer medium-firm — supportive and well-suited to back sleepers and those who prefer a more structured surface. Slightly firmer than 6.0–6.5 medium-firm options.

Let customers speak for us
Great quality products, quick, easy delivery
Fits a standard Koala foam pillow extremely well. Made of a very nice tight weave cotton - no polyester which I detest in bedding. Really happy with my purchase
The cotton covers seem well made and fit as described, shipping is fast
I would suggest this mattress and cover as a perfect solution to dust mite, also with regards to comfort it’s just what you need
I have not been able to sleep under a feather doona until now. The cover is wonderful & delivery was prompt.
Bought to remove neighbours' wood heater smoke from bedroom, works well, haven't checked out cost of replacement filters. Quick delivery, no issues.
Great quality, quick delivery and comfortable
Quick delivery, easy to setup and works great
This mattress encasement is a great solution and alternative to purchasing a new mattress for a child with dust mite allergy. The protected went on easily and provides leave of mind that whatever mites are living inside the mattress are trapped in there. Have purchased all of the products to protect our kids bed and are happy with them. Have been using for over one month now.
The quilt cover encasement feels like it's great quality. Have been using for about one month now and it's providing peace of mind that whatever is inside there can't get out. Washing the quilt weekly was not going to work as the quilt wouldn't have survived such regular washing, so this is an excellent solution.
Great quality cotton material, but it's a bit of a struggle to get onto the mattress.

The product is great quality and was an easy order with very good communication. I have only had one night sleeping with it but was very pleasantly surprised . I must add , I think the cost is great value when compared to getting even a new doona that is adequate for the colder states in Australia . I had my down doona and pillows washed and commercially dried before putting them in the covers and the mattress is all encased now and it is a really big difference . 👍
Efficient postage, easy to put onto the mattress, duvet etc. Daughter finds it comfortable and soft.
