Little in life is more important than a good night’s sleep, both for your physical health and mental wellbeing. So, it’s worth investing in thebest mattressyou can afford it. But if you’ve shelled out a large sum on a mattress, you may struggle to replace it if things go wrong, and that’s why mattress guarantees are so important.
Not all mattress guarantees are created equally. Not only do they vary from company to company, but sometimes different guarantees apply to different mattresses from the same brand.
In this article, I’ll outline the key questions you need to ask to make sure your mattress guarantee will protect you properly.
How long does a mattress guarantee last?

Mattress guarantees can last from anywhere between 3 to 25 years, and often vary within a company between different ranges.
Many mid-range brands are more generous, such asSimba, which currently offers a 10-year guarantee on all its mattresses. And at the premium end of the market, it’s not unusual for guarantees to stretch for decades, such asMarshall & Stewart, which offers a 25-year guarantee, or DreamCloud, which boasts alifetime guarantee.

What does the mattress guarantee cover?

That may seem unfair, but the logic is that mattresses inevitably wear out over time, and can’t be expected to remain pristine forever – so companies must draw a line somewhere. And often they draw that line precisely, for example,Brooke + Wildewill fix sagging of 2.5cm+ in the first 6 months, 3cm+ in the second 6 months, 3.5cm+ after 12-24 months, and so on.
In short, it’s important to understand what is covered and what is not, before you make your purchase. Thankfully, most brands have a page on their website that sets out the terms and conditions of the guarantee in detail.
When can the mattress guarantee be voided?

Typically, you won’t be able to use your mattress guarantee if the company feels the damage to the mattress was your fault. So, it’s worth checking the terms and conditions to see what things they define as voiding your guarantee.
Some guarantees also include specific terms you may not have thought about. For example,Eve’s 10-year guaranteestates that it does not apply when the mattress is taken outside of the country.
How do I claim under the mattress guarantee?

Even if you have a watertight guarantee, it’s worth checking how much hassle it will be to make a claim, and whether there are costs involved. For example, some guarantees require you to fill out a claim form and provide documentation, such as a purchase receipt and photographs of the problem.
Others may require you to bring the mattress to a service centre for inspection, or charge you for pickup. For example, withNectar’s forever warranty, the company will replace your mattress at no charge during the first 10 years of ownership. After that, they will only repair and re-cover your mattress, and you’ll have to pay transportation costs of £65 each way. Note, though, that these charges will be waived if a defect is confirmed.
Is a guarantee the same thing as a free trial?
The words ‘guarantee’ and ‘free trial’ are often used interchangeably in mattress marketing speak, but aren’t the same things at all.
A mattress guarantee is a promise to repair or replace a defective mattress, so long as the defect is the manufacturer’s fault. In contrast, a mattress free trial is a no-strings-attached promise that you can try out a mattress and return it for a full refund or replacement if you’re not satisfied with it.
With a guarantee, you have to show that there’s a defect with the mattress, and that you didn’t cause it yourself. With a free trial, though, there’s no onus to show that the mattress is defective. It’s enough to say that you just didn’t like it, and you don’t have to explain why.
