The Feel of the Onebed Mattress

That largely depends on your sleeping position. As the Onebed mattress has a medium firmness, it is well-liked by a variety of sleepers. Most side and back sleepers seem to enjoy it the most. However, some stomach sleepers don’t find it firm enough. Nevertheless, its comfortable yet supportive and cool yet contouring feel is responsible for all the adulation it has received. 

Materials used in the Onebed Mattress

The Onebed mattress is a multi-layered memory foam and latex hybrid that uses a unique layering to suit a variety of sleepers. Its upper Dunlop latex layer is responsive to your body and also makes for a cool surface. Under it is the memory foam layer that provides spinal support. Beneath it all lies polyurethane foam that supports your weight. To wrap all of it is a plush polyester cover. Simply put, the Onebed mattress is made from premium quality materials that work very well together and give you a good night’s sleep.

Weight and Thickness

The Onebed mattress weighs 38 kilograms. Its (Onebed Original) thickness, which is consistent across all sizes, is 26 cm or 10 inches. Some may think that it is not thick enough but a mattress’s firmness matters more than its thickness.

Onebed Mattress Sizes

Onebed mattress is available in all popular mattress sizes. As it is a mattress-in-a-box, box sizes have also been given.

  • Single: 92cm x 188cm x 26cm

There is no one size that fits all. Whereas a Single mattress may be perfect for a budding teen, a mother of 4 may prefer a King-sized mattress.

Unpacking and Delivery

It is very easy to unbox and unpack the Onebed mattress. As it is a mattress-in-a-box, all you have to do is open it up, remove the plastic cover, and unroll it. After that, it’ll inflate within a matter of seconds and be fit for use. Nevertheless, it is always wise to give it a few days to expand to its original, decompressed size.

However, subject to your availability and location, some delivery charges may be incurred. That only happens with your consent. Moreover, estimated delivery times are in business days.

  • Polyester fabric cover: This wraps up all of the layers of the mattress. It is made of a poly-blend that feels soft and plush. Additionally, the cover is removable and washable.
  • Dunlop latex layer: This layer is highly responsive and provides a slight bounce. Its naturally cooling properties ensure a cool sleep.
  • Visco-elastic memory foam: This memory foam layer provides contouring to your body and gives your hips and spine pressure relief.
  • Polyurethane base: The thick, high-density polyurethane base layer gives the mattress all of its strength and durability. Moreover, it also supports the sleeper’s weight.

Customizable Firmness

You can also shuffle these layers for a firmer or softer feel. This customizable firmness gives the Onebed mattress a significant edge over traditional mattresses.

Onebed Mattress’ Suitability to Australian Climate

Usually, foam mattresses are known to accumulate heat. However, in the Onebed mattress, the naturally cooling Dunlop latex layer is the first surface to come in contact with a sleeper. Moreover, the sleeper is never in contact with the memory foam layer. This allows for a cooler sleep. These features are very important to people living in hot and steamy climates like Australia’s. Hence, the Onebed mattress is a good choice for Australian customers.

Who is the Onebed Mattress Best for?

The Onebed mattress, with its medium firmness, is a great choice for side and back sleepers. However, stomach sleepers may find it too soft. Its minimal partner disturbance makes it a good option for couples as well. Finally, thanks to the Dunlop latex layer, it is breathable and gives a naturally cool feel. This is great for the steamy Australian summers.

The longevity of the Onebed Mattress

The Onebed mattress is a very durable mattress with a limited warranty of 15 years (Onebed Original). Any defective part is repaired and replaced by the company without any charge to the customer for the first claim. For subsequent claims, the buyer is charged up to 30% of the retail price for the handling and processing fee. Nevertheless, Onebed mattress is made with premium quality materials that are durable and stand the test of time.

Off-Gassing Smell

A new mattress does have an odor to it but it is not dangerous in the least. The smell is actually due to the off-gassing phase of the new mattress. It goes away in less than a week. This process can be hastened by improving the room’s ventilation or by putting the mattress in the open air. The most important thing is that it is non-toxic and temporary.

Onebed vs Koala Mattress 

Both products are largely comparable. Both are mattress-in-a-box variety. They have similar prices, trial periods, and delivery fees (free). Both are medium-firm and preferred by back and side sleepers. However, Onebed eclipses Koala with its 15-year warranty. Nevertheless, Koala has uniquely breathable Kloudcell technology, provides great comfort and support, and has a rabid fan base. It would be unfair to give precedence to one over the other.
