What safety tests have been done?

We put the Sonno mattresses through serious testing for comfort, design and most importantly, safety. Sonno mattress is SGS certified.


Why should I avoid the spring mattress?

You may be surprised to find out that the mattress you are lying on could, in fact, be acting as a radiation antenna. This is a problem because an antenna will amplify electromagnetic waves, and some electromagnetic radiation has been linked to certain diseases. You don't want to be spending a third of your life lying in an electromagnetic field, yet this is exactly what you are doing if your mattress has any metal in it.


Which are the benefits of a latex mattress?

The latex mattress has three properties that help you to sleep well and live better:

  • the mattress is breathable, thanks to the latex porosity
  • the mattress is hygienic, since latex is a natural fiber
  • the mattress supports your weight, thanks to the elasticity of the material

The mattress must have an elastic structure which supports the body, while its porosity ensures perfect breathability that rapidly eliminates the body’s humidity. The result is a breathable, hygienic mattress, as well as one that is welcoming and supportive.


What is natural latex and why is it used?

Latex foam is produced by vulcanising liquid latex. The vulcanisation process crosslinks latex particles with sulfur through the application of heat and accelerators such as zinc oxide. Latex does not retain heat and provides a high level of pressure relief from its bounce-back effect. It also provides excellent motion-transfer properties.


Why is Sonno mattress priced much lower than a similar mattress sold in a store?

Most mattresses are priced unrealistically high. By selling online, we do not waste money on large showrooms with pushy salespeople and we cut away the multiple channels of distribution, advertising and high showroom rental. The sale is done directly from the factory to consumers. By compressing the mattress into a box, we reduce the storage and delivery costs too. Just a brilliant mattress sold at a fair price.


How many types of mattresses do you have?

We have 2 mattresses, the Sonno Original and the Sonno Lite. Sonno Original has 3 layers of Natural Latex, Memory Foam and Support Foam, while the Sonno Lite has 2 layers, Memory Foam and Support Foam. While the Sonno Original is 23 cm (9” thick), the Sonno Lite is 18 cm (7” thick). Sonno Original also has a removable and washable cover, while Sonno Lite has a knitted fabric cover not removable. 


What’s the difference between Sonno Original and Sonno Lite?

While the Sonno Original is 23 cm (9” thick), the Sonno Lite is 18 cm (7” thick). Sonno Original also has a removable and washable cover, while Sonno Lite has a knitted fabric cover not removable.

Mattress Care

Bear in mind that the firmness might be different according to the base used (i.e. divan and floor base might feel firmer, slatted base might feel softer). We suggest a solid flat surface.


Can I sleep on my mattress right after unboxing it?

We recommend allowing one hour for your mattress to expand before sleeping on it. After 24 hours, your mattress will have fully taken shape and will perform at its best!


Should I flip or rotate my mattress?

The Sonno mattresses are designed to be used one way up, so flipping is not required. We recommend rotating the mattress 180 degrees every six months to maximise performance and durability.

With the Sonno Original you can easily unzip your mattress cover and hand-wash it in warm soapy water. Remember to line dry the cover and treat it as you would do with your favourite dress. The Sonno Lite does not have a removable and washable cover, however you can easily use a steam cleaner periodically to refresh and sanitise the soft knitted fabric of the cover.

Once you have received your new Sonno, setting it up is quick and simple – just follow these steps:

  • Unbox your Sonno box on its side in the room you’ll be using it.

  • Flatten out your Sonno and tear open the inner plastic wrap with your hands.

  • Allow an hour for the mattress to expand. It will take 24 hours to fully expand, but you can use it almost immediately.

What makes the Sonno Pillow different?

The Sonno pillow is made of one memory foam piece designed to maintain a specific structure to support your head and neck no matter how you sleep. Fill pillows use a variety of materials (cotton, down, polyester, etc.) to make up the inside of a pillow but often need maintenance to keep their shape.


How do I wash my Sonno Pillow?

First, remove the cover from the foam. You can machine wash the cover, in cool water with a mild detergent and a tumble dry on low.


What’s the best pillow for my sleep position?

Sonno sets out to design a single pillow that could accommodate all sleeping positions. Whether you like to sleep on your side, back or stomach, you will feel supported by The Sonno Pillow.


I don’t remember the last time I replaced my latest pillow. How do I know I need a new one?

Experts recommend replacing your pillow every one to three years — but we understand that doesn’t always happen! If your head doesn’t feel supported, you need a new pillow. No matter what position you lie in, the pillow should be under your head (not your shoulders) and its thickness must keep your head to be in a normal position.



Why we exist?

You undoubtedly know that selecting a mattress is often a tedious, complicated old-fashioned process. In the past, you may have ended up buying what an unreputable salesman was pushing, someone who cared more about his or her financial bottom line than your true comfort. Maybe you had the opportunity to lie on a mattress for a few minutes before the purchase, or maybe you didn’t, but either way it wasn’t enough time to allow for such a critical, life-altering decision. No more.

Sonno is different. We make having a great night’s sleep easy. You conveniently order online, the exceptional mattress comes in a box and you try it in the comfort of your home for 100 wonderful nights, risk free.


What's behind the Sonno name?

‘Sonno’ was chosen as a name because it’s Italian for ‘slumber’. Your bed is your intimate and personal space where you should feel relaxed, safe and utterly at ease. We don't take that for granted and have made it our mission to live up to that promise every single day.
