Design & Construction

The Advantages And Features Of A Koala Mattress

Materials for Mattresses

The Koala mattress’s cover is constructed of the following materials:

70 percent polyester, 30 percent TENCEL make up the cover top.

The fabric on the cover side and the underside is 100 percent polyester.

Layers in a Mattress

So, what is the composition of the Koala mattress?

The mattress has two layers underneath the cover.

Kloudcell is on top (comfort layer).

The open-cell foam architecture of this layer is one of its most notable features:

  • It’s a 6cm thick layer.
  • Polyurethane foam is used to make this product.
  • Pressure is absorbed.
  • Is made to allow air to flow freely throughout the mattress.
  • Allows the mattress’s heat to escape.
  • Zero partner disturbance Koala mattress technology

The second layer is the mattress’s Eco foam support layer, which consists of the following components:

  • Is a 16-centimeter thick ultra-resilient foam
  • Provides additional assistance
  • Ensures the mattress’s lifespan
  • The mattress is made up of only two pieces of foam, which is extremely disappointing when compared to other mattresses on the market.

Layers of Ecosa Mattresses

The layers in the Ecosa mattress are meant to deliver a supportive, peaceful, and cool sleep.

Three interchangeable foam layers make up the mattress’s core:

1st Layer

The G-7 Gel Memory Foam Layer conforms to your shape, relieving pressure spots and letting your body sink easily. Temperature control is aided by the use of gel particles.

Layer in the Middle

The Eco-Tex Memory Foam Layer: This layer has the perfect amount of bounce and resilience, giving it a cradling sensation. Due to its foam composition, it is more breathable and durable than latex.

The layer at the Bottom

High-Density Ergonomic Support Foam: This layer has grooves that help with ventilation, spine alignment, and pressure point relief. This layer allows the mattress’s no-partner-disturbance function to work.

Sleeping Duck Mattress Construction

There are four layers to the construction:

1) BreatheTech Cover: A bamboo cover that can be washed.

2) Anti-Gravity Surface Foam: Cushioning foam layer

3) Precision Firmness Pads: A high-density foam layer that can be adjusted from firm to medium firmness.

4) Motherboard: a bottom-mounted pocket spring mechanism that provides support.

It’s said to breathe better than a latex mattress.

It has a 10-year warranty and is available in Firm, Medium, or ‘Half-Half’ styles. It is heavy, weighing 53 kilograms. There is no cost for shipping.

Many customers appreciate the customizability of the options, which allow various sleepers to adjust their demands to their preferences. When you have a side-sleeper and a back-sleeper sharing a bed, for example, this is handy. Customers also say that because of the high quality, the mattress lasts longer than comparable in-a-box mattresses.

The mattress is built in China while the foams are produced in Australia.

People frequently pick between Sleeping Duck and Koala mattresses. So, which one should you pick? They both have thousands of great reviews and provide extensive warranties. The Sleeping Duck is an excellent alternative for couples who have diverse sleeping preferences because it is a hybrid mattress that can be customized for firmness on both sides. The Sleeping Duck mattress is constructed of springs and foam, whereas the Koala is built entirely of foam. Koala is a wonderful choice if you’re seeking an all-around mattress on a tight budget and don’t need to adjust the firmness.

From top to bottom, the mattress is made up of four layers:

Cover made of bamboo

Breathability is a priority.

This layer is unchangeable.

Note that just the layer beneath the first foam layer (yellow) changes between the medium and firm mattresses.

GECA has given its approval.

Pocket Springs with 5 Zones

It gives your body support.

5 Zones of Support: Provides support for the heaviest sections of your body (shoulders and hips). However, you should use it sparingly in places where it isn’t required.

Zero partner disturbance is supported.

Partner Disturbance is at a minimum.

The mattress’s structure (5 zone pocket springs and mattress layers) minimizes companion disturbance during the night.

This feature has been mentioned in a number of positive mattress reviews.

Firmness & Feel

Sleeping Duck vs Koala vs Ecosa – Feel & Firmness

Sleeping Duck:

According to one Sleeping Duck product review, this mattress is unique for a variety of reasons. One of them is its one-of-a-kind construction and material mix, which adds optimum comfort and softness while yet maintaining support and firmness.

To provide adequate support, the Sleeping Duck mattress employs a blend of high-density foam, comfort foam, and pocket springs. According to our Sleeping Duck mattress review, the top layer has the one-of-a-kind Hyper-Adaptive foam and is designed for maximum comfort.
