Tranquil sleep Mattress 6ft

The Tranquil Sleep is the softest mattress in the Serenity Collection, and at 35 cm it is also among the deepest. Cool Cell foam and a 1000-spring comfort layer sit above a foam-encapsulated pocket unit, so you sink in properly rather than resting on the surface. The micro Tencel cover keeps that depth from ever feeling stuffy.

Soft, cocooning comfort with real depth

Respa rates the Tranquil Sleep soft. Generous comfort layers let your shoulders and hips press in far enough to release the pressure they carry, which is what people mean when they describe a mattress as cocooning. Side sleepers benefit most. Anyone who finds firmer beds leave them stiff by morning will feel the difference quickly.

Cool Cell foam for temperature control

Soft, deep mattresses trap heat, because more of your body sits below the surface. Cool Cell foam works against that, moving warmth away instead of holding it against you. It is what lets the Tranquil Sleep offer this much cushioning without sleeping hot, and it earns its place through the summer months.

Micro Tencel that wicks moisture naturally

Tencel comes from wood pulp and handles moisture far better than standard polyester. It draws perspiration away from your skin and releases it, so the sleep surface stays dry and the fabric feels cool to the touch. It is also naturally smooth, which matters against skin every night.

2,000 Spring Count with a comfort layer over pocket springs

Above the main 1,000 pocket unit sits a second layer of 1000 mini springs, small enough to respond to the finer contours of your body while the larger springs below carry your weight. Two levels of spring response is what stops a soft mattress from feeling unsupported, and it keeps your spine in line even as you settle deep into the surface.

Foam-encapsulated edge support

A foam frame encases the spring unit on all sides, holding the borders firm despite the depth of soft filling above. Without it, a mattress this plush would give way at the edges. You sleep on the full width instead, and sitting on the side to dress stays comfortable.

Caring for your Tranquil Sleep mattress

The Tranquil Sleep comes as a non-turn mattress. Rotate it head to toe every few months using the handles to spread the wear evenly across the comfort layers. At 35 cm you will need deep fitted sheets, so check your bedding before you buy.

Who the Tranquil Sleep suits

Choose the Tranquil Sleep if you want the softest mattress in the collection, if you sleep on your side, or if you have wanted a deeply cushioned bed but worried about overheating.
