Mix: Crafting the perfect cover

Washable hypoallergenic pressure layer

The quilted top layer provides a soothing sleep surface to nestle into. And it’s not all about the comfort; Sid considers hygiene, too. This surface layer is hypoallergenic and can be quickly removed thanks to the premium zipper. A quick machine wash will rejuvenate your cover again and again.

Premium cotton

High-end quality yarn is expertly woven to create the spectacular denim detailing of Sid’s debut cover collection. Soft yet durable, make a design statement with a mattress that looks like nothing else on the market. The cover is designed to slowly crease and fade until it’s a unique reflection of your body and sleep patterns.

Signature pocket detailing

The signature pocket detailing provides a wonderful talking point and a safe place to stash all those bedroom essentials. Finished with Sid’s autograph on the iconic red tab as a guarantee of quality and authenticity.

Switch: Update,
Not Update

Sid’s unique Switch system allows you to grow, mix and update your bedroom, starting with your mattress. Change up the entire look of your bedroom in five minutes with a Sid mattress cover – the quick way to transform your Sid mattress. The launch collection from Sid, Denim Dreams, offers up Midnight Blue and Nocturnal Noir in a denim finish. As the collection expands, so do your design possibilities.

Each Sid mattress is shipped with a cover of your choosing, but you can add to and expand your collection. Whether you choose Midnight Blue or Nocturnal Noir, why not switch it up by adding another cover to your order. When you’re ready for a change in the bedroom, Switch it!

However you sleep, sleep with sid.

One mattress to rule them all. Sounds ambitious, we agree. Some people sleep on their side, others on their front, you may sleep on your back. And you probably share your bed with someone with a completely different body type and sleep position to you. Thanks to the unique Sid mattress Mix, you’ll both be in bedroom heaven. We engaged our mattress engineering expertise to select a range of high-tech materials designed to learn, adapt and compensate to any sleep preference. The ideal mix of bounce and support for everyone.

Super on any surface, better on any base

Divan base? Slatted frame? Sid loves them all. We designed your new Sid mattress to perform across a range of bases.
