Our Sleep technology is built to last. If you buy directly from simbasleep.com, your sleep product comes with a 10-year guarantee automatically.
If you buy a qualifying Simba mattress from one of our authorised* retailers, it comes with a five-year guarantee. You can extend this to a total of 10 years by registering your product with Simba.
The guarantee is subject to the full terms and conditions below.
We know it can be a bit of a snooze reading small print, so we’ve summarised some of the main points people ask us about below. But it’s important to note this is a summary only and does not replace the full terms and conditions, which can be read here: Mattresses, Toppers, Beds.
Bought directly from Simba: Your qualifying Simba technology is covered by a 10-year guarantee from its delivery date. You do not need to register it.
Bought from an authorised retailer: Your qualifying Simba mattress is covered by a five-year guarantee from its delivery date. Register your product with Simba to extend the guarantee to a total of 10 years from its delivery date.
Registration does not affect your statutory rights or change who you should contact if you need to make a claim.
While we make every effort to avoid them, errors can happen from time to time. Our guarantee covers you for any issues that could reasonably be said to have started with us - like foam that cracks, a faulty zip or significant dipping (see the chart in our full terms).
It’s normal for mattresses, beds & toppers to show signs of use over the years, so we don’t consider ordinary wear and tear a fault under the guarantee. We also exclude soiled items and damage caused by accident (including by pets), disaster or misuse.
We know it sounds like common sense, but obviously you’ll need to use an appropriate base, a mattress protector, and to make sure your mattress, topper or bed doesn’t get wet or exposed to the elements. Other than that, all you need to do is rotate your mattress 180° on its base regularly - once a month for the first three months, then every three months thereafter.
Please contact the place you bought your mattress, topper or bed from within 30 days of noticing the problem, with your proof of purchase available.
If you bought directly from simbasleep.com, click here. You should do this within 30 days of spotting the problem, with proof of purchase to hand. We might arrange to send out an independent quality team to assess the issue, but our care team will let you know exactly what to expect next. If you bought from an authorised retailer*, please contact that retailer first, including where you have registered your product with Simba.
If you registered your product, your registration confirmation email can be used as evidence of the extended guarantee. Registration does not replace or affect your statutory rights against the retailer.

After purchasing our Simba mattress, both me and my fiancé are now able to get a great night’s sleep in comfort and wake up with no back or neck pain. One of, if the not the best purchase we’ve made in a long time.
