The Slumberland Duo 1400 2-in-1 is a double-sided mattress that provides you with year-round comfort. For every season, whatever the weather. Developed to perform the whole year through, all you need to do is turn the mattress twice a year, switching between the spring/summer and autumn/winter sides.

The spring/summer side features our innovative cool-touch fabric, SensICE, to draw heat away from your body and help keep you cool. There’s a natural Pro-Bio treatment on this side too, to help prevent allergens that tend to be more prevalent during spring and summer. Once the nights start to get colder, just turn the mattress over to the autumn/winter side where you’ll find a snuggly "Teddy bear" fabric, plus wool, to help insulate your body and keep you cosy as you sleep.

With 1400 pocket springs adapting individually to your body movement, you’ll get superior responsive support every night. Offering a unique sleep experience, each clever spring is encased within its own individual fabric pocket for minimum motion transfer – so that even the wriggliest of sleepers can sleep happily. Each spring works hard to support your body’s contours and provide reactive support where you need it most.

Thanks to the dynamic perimeter edge support, you’ll be able to use the entire mattress, from edge to comfy edge. We’ve reinforced the outer rows of springs to help provide a smooth and even sleep surface. This means you can stretch out and still feel the same intense support across the whole mattress.

Our Truecomfort filling layer, made using recycled plastic bottles, makes this mattress that bit more future friendly too. Giving you an additional layer of comfort and support, you’ll be counting down the hours until bedtime.

With a deep quilted finish, the Duo 1400 is in a league of its own. Available in a comfort rating of Medium or Firm, the mattress provides the perfect level of support. Not only does this mattress offer a revolutionary sleep experience, but it’s also super easy to care for.
