Sealy UK stands out for its commitment to innovation, quality craftsmanship, and extensive research. Sealy combine cutting-edge technology with decades of expertise to create posturepedic mattresses that deliver exceptional comfort and support.

Do Sealy offer different types of mattresses?

From orthopaedic supports to mattresses with high-tech body-moulding memory foam and mattresses with hypo-allergenic natural latex, there’s something to suit everyone.

Why is mattress firmness important?

Not everybody likes to sleep on the same type of mattress. The mattress firmness primarily relates to comfort, but it can have health benefits too.

For example, firmer mattresses can offer a greater spine support to sleepers who suffer from back pain during the day to provide a good night's sleep.

What are the benefits of a Sealy mattress?

Sealy mattresses have a range of benefits. Their PostureTech system is unique to Sealy and offers zoned support throughout the mattress, adjusting its support so your spine is properly aligned.

Posturepedic mattresses also benefit from EdgeGuard, a technology that offers edge-to-edge support across the mattress width and helps to enhance the mattress durability.

How does Sealy ensure a good night's sleep?

Sealy incorporates advanced features like zoned support systems, memory foam, and cooling technologies to promote optimal sleep. Their posturepedic mattresses are engineered to provide proper spinal alignment, pressure relief, and temperature regulation.

Absolutely! Sealy offers a diverse range of mattresses designed to cater to different sleep preferences. Whether you're a back, side, or stomach sleeper, you'll find a Sealy mattress that suits your needs.

Are posturepedic mattresses suitable for people with back problems?

Sealy work with the International Orthopaedic Advisory Board and have done for nearly two decades. The board is made up of Orthopaedic surgeons, bio-mechanical engineers and medical scientists. 

Backed by scientific research, Sealy’s Posturepedic technology works to provide you with the correct support by aligning the body’s position while you sleep.

Sealy UK are so confident in the durability of their mattresses that they offer a 5-year manufacturing guarantee on all their products.

What is the lifespan of a Sealy mattress? 

The average lifespan of a mattress is 8-10 years. If you buy a quality mattress, such a Sealy and follow the care instructions, it should last a few years longer and will offer you a consistent level of support and comfort during this time.

•    Sealy king size mattress – 5ft x 6ft6 (150 x 200cm)
•    Sealy super king size mattress – 6ft x 6ft6 (180 x 200cm)

Can I use my new Sealy mattress on my existing divan base?

There’s nothing to stop you, but bear in mind that your existing base has had the same amount of wear and tear of the mattress that you are replacing.

When buying a new mattress to replace one that’s past it’s best, you should always consider replacing your old base too. Nothing lasts for ever.

How can I care for and maintain my Sealy mattress?

Caring for your new mattress is so important to enhance its longevity and to ensure it retains its support and comfort throughout its life.

If it’s a double-sided mattress, we recommend that it’s rotated from head to toe and flipped over on a regular basis. Single sided ones only need to be rotated.

For all mattresses, we recommend that you use a quality mattress protector to prolong the lifespan of the mattress and protect it from spills and stains.

A care instructions booklet will be enclosed in your new mattress. Simply follow these instructions for a quality night’s sleep, every night.

How to clean a Sealy mattress

Unfortunately, no matter how careful we are, accidents do happen and spillages can ruin the look of your mattress. We recommend cleaning any spills as quickly as possible with warm soapy water, baking soda and a cloth.

Rinse the cloth in cold water, then dab the stain with the cloth. Sprinkle the baking soda over the stain and leave for 30 minutes. Rinse the cloth with cold water again and dab the stain until it lifts. Repeat this process as many times as necessary, then leave to dry.

Why buy a Sealy mattress?

A Sealy Posturepedic mattress offers a support system that’s unique from top to toe, for a sleep that’s best in class.

They truly believe that this is the only mattress that delivers genuine support that everyone can feel and the true comfort that everyone deserves.

Every Sealy Posturepedic mattress is made to be trustworthy, resilient and durable - night after night…year after restful year.
