The right size for you

Super King Mattress Topper Size

Size dimensions are 180cm x 200cm (5ft 10” x 6ft 6”). Each one fits a super king size mattress perfectly, adding an extra layer of comfort to your sleeping space. 

Our Range of Bed Toppers

We know that sleep is an extremely personal experience, which is why it’s so important to make the right decision. To help you choose your topper, here’s a breakdown of some of our bestsellers and what they offer. Each one comes highly recommended by previous customers.

Cheap Memory Foam Mattress Toppers

Want to add comfort but don’t want to blow your budget? We have a range specifically designed for your needs. Our Essentials 5cm topper comes with a value for money price tag. Despite this, we haven’t cut corners when it comes to quality. It’s made entirely from hypoallergenic materials which means it’s perfectly designed for allergy sufferers. It also comes with a one-year warranty to give you peace of mind. 

Looking for a slightly different depth? This Essentials 10cm topper is thicker, while still offering many of the same features. We believe we’ve found the perfect blend of quality and comfort, while providing our customers with some of the most competitive prices out there. 

Cooling Mattress Toppers 

If you’re prone to overheating at night, we’ve developed a range specifically for you. Our Coolmax 5cm topper wicks away heat and moisture while you sleep, ensuring you’re not disturbed at night. It also provides high levels of support for pressure points. This makes it suitable for a range of different sleepers, including those with back pain. Its machine-washable cover allows it to stay as long-lasting as possible, keeping it protected from spillages and stains.

Need an alternative? Our Coolmax 7.5cm topper has a slightly varying depth, but is otherwise the same. It’s also made from hypoallergenic materials and comes with a one year warranty. It’s the perfect choice for those who need temperature sensitivity while they sleep. 

Looking for the ultimate blend of cooling technology and luxury? You can’t beat our 4G Aircool mattress topper. If you’re looking to transform your existing mattress into a irresistible sleeping surface, this is the perfect choice. The ‘open-cell’ structure allows air to naturally flow through the topper, wicking away moisture and excess body heat. What’s more, its hypoallergenic materials make it less likely to pick up dust mites. Of course - it’s extremely comfortable too.

Luxury Mattress Toppers

Few can rival these toppers when it comes to a luxurious feel. Cooling, soft and supportive - this Zen 5cm Kooltop mattress topper is a must-have for those seeking a great night’s sleep. It’s made using unique fibres that are not only luxurious to touch, but also allow air to permeate, helping you stay cool. The foam itself also provides relief and improves blood circulation. 

Looking for a different depth? We also have a Zen 7.5cm Kooltop mattress topper differs slightly, while still offering the perfect combination of cooling technology with a soft finish. This one is extra deep and slightly heavier. It provides comfort for your body the whole night, reducing the need to toss and turn. 

Alternative Sizes 

If you’re looking for something different, we have a number of memory foam mattress toppers for you to choose from. Single, double and king - we’ve got all your needs covered:

Why Do You Need a Soft Mattress Topper?

A topper provides numerous benefits for your health and wellbeing. Here’s a closer look at just some of them:

Extra Layer of Comfort

Let’s face it - we’re all looking for the secret to a great night’s sleep. A topper can help you feel fully rested each morning, creating a luxurious and supportive sleeping surface. If your mattress isn’t as comfortable as it could be, for example, this is a welcome change.

We find mattress toppers are particularly popular with those living in rented accommodation, or who simply enjoy a luxurious feeling. They’re also particularly well-suited to guest bedrooms. Note: they won’t be appropriate for certain sofa beds. 

Particularly when combined with the feel of a memory foam pillow, you’ll find it near-impossible to get out of bed in the morning. Just a few small changes can transform your sleeping area for the better. 

Affordable Alternative 

Want to enjoy comfortable nights but don’t want to break the bank? A topper can provide an affordable alternative to a memory foam mattress. It offers many of the same features, such as pressure point relief, at a much lower price. 

Why Choose Memory Foam?

Memory foam has skyrocketed to fame as one of the most popular choices of materials when it comes to beds. This is for good reason. It offers countless benefits for your health, making you feel happier and better rested. These include:

  • Improved circulation 
  • Increased airflow
  • Full body support 
  • Pressure point relief 
  • Lumbar support
  • Strain removal
  • Stiffness relief 
  • Shock absorbance 
  • Eased muscle pain
  • Body contouring 

Together, these make for the best possible night’s sleep - every night of the week.

How to Use

Before You Buy a Mattress Topper

There are some considerations you need to make before parting with your money. For example, you need to ensure your bed frame will adequately support your mattress. A topper can’t solve the cause of all discomfort. If the slats are too far apart, you’ll struggle to get the support you need. This could also cause your mattress to sag.

If your mattress is lumpy or already sagging, a topper won’t fix this. These are two tell-tale signs that you need to replace your mattress.
