Frequently Asked Questions

Our Super King Size Mattresses measure 180cm wide (5.91 ft) by 200cm long (6f ft) making them a very generous mattress size. Whether you’re a light sleeper and are frequently getting disturbed by your partner during the night, or you're simply looking for a mattress where both of you can starfish, our king size mattresses certainly make fantastic options for you. 

Depending on the mattress type, our super king mattresses can also vary in thickness. For example, the Cool Blue Relief Mattress 6ft Super King mattress has a depth of 20cm, made up of high-density foam, cooling gel and eco-friendly support foam for a combination of comfortable, temperature-regulating materials. Alternatively, you could purchase our Regency 3000 Pocket Spring Hybrid Mattressthat’s 30cm thick, for a plush and supportive feel. 

A super king mattress typically weighs between 30kg and 70kg, depending on its materials and construction. Foam and hybrid mattresses are often lighter and easier to move, while pocket sprung mattresses and those with additional comfort layers may weigh more.

Despite the size of the large king size mattress, they are often easy to move if you have someone to help you. Crafted with convenient handles on either side, the mattress is easier to turn and flip when it’s time to freshen up your sleep set-up. 

If you’re fancying the luxury of a super king size mattress but you think this option is a little too large for your bedroom, we also have a collection of 5ft king size mattresses and double mattresses that are equally as comfortable and sumptuous. 

The comfiest mattress often depends on personal preferences, factoring things such as size, materials, density and much more. Many people like firm sleeping surfaces that help relieve pressure on their joints, whilst others like to sink into their mattress. 

Climate Control Mattresses

Our climate control mattresses are designed with clever temperature-regulating materials such as Cool Blue Gel and breathable cashmere. Whether you find yourself getting hot during the summer nights, or really cold on wintry evenings, a king size climate control mattress can help regulate your body’s temperature for great sleep all year round. 

Memory Foam Mattresses 

A memory foam mattress is perfect for those who love to sink into their mattress, as opposed to a firm sleeping surface. The latex materials of the memory foam mattress contour to your body’s shapes as you sleep on it, perfect if you have a favourite sleeping position. Shop memory foam mattresses to feel snug and cosy! 

Orthopaedic Mattresses 

Our wide range of orthopaedic mattresses are designed to offer targeted support to relieve pressure on your joints. If you love firmer sleeping surfaces, buying a king size orthopaedic mattress is certainly a great choice for you. Designed with spinal alignment in mind, these mattresses offer support and comfort to help you settle into a restful night's sleep.

Pocket Sprung Mattresses 

Shop our wide range of pocket spring mattresses for reduced motion transfer. With thousands of individually nested pocket springs, these mattresses are perfect if you want to have a firmer sleeping surface and feel less movements from your partner.  

Hybrid Options 

Many of our mattresses are designed with a combination of materials and technologies, helping you get the best of both worlds of both soft and supportive mattresses. Shop our hybrid mattresses to help you find an option that suits your sleep preferences! 

If you’re still unsure as to which mattress is right for you, why not check out some of our guides?  Here, we break down everything you need to know about our different mattress types.

We sell a wide range of super king mattresses, each crafted with premium materials that stand the test of time. From supportive orthopaedic options, soft cashmere mattresses, to cosy memory foam and convenient rolled mattresses, you’re sure to get your hands on the one you like.

Fantastic Bed!

Bought a bed and mattress from Aspire recently and can’t praise them enough. Customer service and communication were fantastic throughout and the quality of products is superb. Highly recommend!

Great bed

So happy with our bed! So well made, the quality is so high at such an amazing price. Excellent customer service, very responsive to all queries! Will definitely order again for our spare room!

- Leah Harris
Lovely bed

BEST MATTRESS! since receiving this mattress I have had the most relaxed & comfortable sleep, I received this mattress with the best delivery service making it super easy.

- Jemma Azzopardi
Happy customer

Decided to buy after reading the reviews and I have to say I agree with them. It's a good looking bed, decent quality but a bit time consuming to build. It took 2 of us about 3 hours.
