Kmart’s Mattress-in-a-Box Review

Mattress-in-a-box is a revolutionary product that has hit the market recently. Today, these easy-to-transport mattresses are a part of nearly every mattress manufacturer’s product range.

One such manufacturer is Kmart, which has released its mattress-in-a-box for the lowest price tag in the Australian market.

Although its low price has made Kmart’s mattress-in-a-box appealing for those who are looking for low-cost options, the question is whether this mattress is high-quality enough for you to buy it. Let’s find that out.


Price is probably the only factor that gives Kmart’s mattresses an edge over other mattresses available in the market.

Where the average price for a mattress-in-a-box in the Australian market is about $1000, Kmart offers its product for as low as $149-$399.

Ease of Purchase

This product can be bought in four sizes — king, queen, double, and single — from Kmart’s official website. The option to ‘click and collect’ is currently not supported by Kmart, which means that the only option for you is to get it delivered to your address. However, unlike its competitors, Kmart will charge you a delivery fee.

Note that Kmart mattresses are only up for sale in QLD, VIC, NSW, and WA.


The biggest flaw of Kmart’s mattress is its poor build quality. The springs used are really bouncy, unstable, and fail to offer good support to your spine. Also, the extra bounciness in this mattress leads to annoyingly high partner disturbance.

Poor quality — though understandable because of the low price — makes this mattress really unsuitable for people who want to have a good night’s sleep.


Kmart’s mattress uses a grey and white color theme and looks pretty basic.

The cheaper versions look a little bare but the more expensive ones are pretty decent and clean.

Trial Period, Return Policy, and Warranty

Unfortunately, like other box products, Kmart’s mattress doesn’t come with a trial period. This means that once bought and opened, it cannot be returned. The only return that Kmart will process is a product that is still sealed.

Having a no-trial policy doesn’t allow you to ‘try before you buy’ and, thus, is one more reason why you would want to consider buying mattresses from another brand.

However, although Kmart doesn’t have a trial option, it does offer a 5-year warranty for its product, which is pretty impressive for a product of this price and quality.


Like all the box mattresses, the installation of Kmart’s mattress is pretty simple.


  1. Unpack it, which will hardly take 10-15 minutes
  2. Leave it for 24 hours to get decompressed
  3. Use it!

Toxic Hazard

Another issue with Kmart’s mattress is that it does not hold any ‘non-toxic’ and ‘eco-friendly’ certifications. These certifications are there to ensure that your mattress is made in a way that does not harm the environment and that there are no toxic chemicals left in your mattress that can harm you.


The failure of Kmart to get their products certified really leaves a question mark on the quality of their mattresses.

Should You Buy Kmart’s Mattresses?

Despite offering the best price, Kmart’s mattress is full of flaws and offers very low value for money. Instead of buying it, you should go for a better alternative — such as Zinus mattress — even if that means a higher price.

A higher price is worth it as long as you’re getting a high-quality, safe, and comfortable mattress.
