Bed Guarantees – What You Need to Know

When buying a bed, it is important to look for proper guarantees to ensure that your purchase is secure and protected.

Guarantees are a form of assurance that a product will be of good quality and will last for a certain period of time. This is especially important when purchasing a bed, as it is a major investment and you want to make sure that it is a sound purchase. 

If a bed is not adequately covered by a guarantee, you may easily be left with a product that is sub-par… and likely to need to be replaced within a short period of time. In the long run, this can end up being an expensive and inconvenient process. 

Most bed manufacturers will offer some kind of guarantee; whether it is a limited warranty or a full money-back guarantee (which is generally accompanied by a long list of terms and conditions). 

Ultimately, it’s essential to understand how a guarantee is of benefit to you; and what criteria constitute a quality guarantee. 

What To Look For in a Guarantee

It is important to read the details of the guarantee to make sure that you are fully covered – it is essential to understand exactly what is covered and for how long. This will help to ensure that you are getting a bed that is of good quality and that you can rely on for years to come.

The Impact of Mattress Testing on Manufacturer Guarantees

Mattresses need to undergo numerous tests before manufacturers can provide guarantees. This is because it is important to ensure that the mattress is safe, comfortable, and durable. 

Safety tests are conducted to ensure that the materials and construction of the mattress meet safety standards.

Comfort tests are conducted to ensure that the mattress provides the correct support, comfort and pressure relief for a good night’s sleep. 

Durability tests are performed to establish if the mattress can withstand regular use and still maintain its quality. 

All of these tests help to ensure that the mattress meets the manufacturer’s standards; and will provide customers with a good experience.

The Importance of Mattress Testing 

It is standard practice for bed manufacturers to conduct tests on fabrics or materials used in the construction of beds. 

This is due to the fact that these materials are essential to the safety, durability and longevity of the bed. 

Manufacturers need to ensure that the materials used in the construction of beds are strong enough to withstand the weight of the user, and the amount of stress placed on the bed over time. 

What is a Strength Test?

Strength tests involve applying pressure and tension to fabrics or materials in order to determine their tensile strength. This is useful in assessing the amount of force that a material can withstand before breaking. 

Strength tests are conducted in many industries to help manufacturers evaluate the suitability of materials (such as fabrics, yarns, and ropes) for their intended uses. Ultimately, it helps manufacturers to determine the quality and durability of various materials.

This helps to identify any weak points in the material, as well as its ability to hold up under pressure. The tests can also help to identify any potential safety risks associated with the material; such as the risk of the material deteriorating over time due to wear and tear. 

In addition to strength tests, bed manufacturers also conduct tests to determine the flammability of the fabrics or materials used in the bed. These tests help to ensure that the material is flame resistant and will not easily catch fire if exposed to a flame. 

It is worthwhile mentioning that wool is known as the most flame resistant of all natural fibres since it is made of the protein keratin (Science Direct, 2013).

By conducting strength and flammability tests, bed manufacturers are able to ensure the quality and safety of their products. This ensures that consumers can rest assured that their beds are safe and reliable.

The Strength Test Results Are In!

Wool is better than hollow fibre because it can withstand more bends and twists before breaking. 

Wool can also absorb more energy than hollow fibre, which makes it more durable and able to withstand more strain. This is due to its natural elasticity and resilience. 

Wool is a strong, resilient material that is less likely to fray or tear – unlike hollow fibre.

Hollow fibre can withstand a maximum of 1800 bends in a strength test. Wool, on the other hand, can withstand in excess of 80 000 bends!

Why Mattress Density is Important

The density of a mattress is expressed in kilograms per cubic meter (kg/m3).

A mattress with a greater density indicates superior quality and longevity and should not be mistaken for firmness.

The density of a mattress will affect its responsiveness, durability, motion isolation, and cost. Typically, mattresses with higher densities are more durable and maintain their shape for longer than those with lower-density counterparts.

It is also worth mentioning that the density range for urethane mattresses (i.e. memory foam) is typically between 12 – 25 kg/m3. This is far inferior to that of organic latex. In fact, the density of all Naturelle Mattresses are in excess of 100 kg/m3! This is a fantastic indicator of the durability and longevity of our organic latex products.
