Why Should You Use a Mattress Topper?

If you need more convincing on why mattress toppers are so beneficial, we’ve taken a closer look. Here are just some of the reasons behind their popularity.

Comfortable and Supportive

Say goodbye to back pain! Memory foam toppers offer orthopaedic qualities, such as aiding spinal alignment, and they have the ability to adapt to the shape of your body, absorbing your movement, weight and relieving pressure points. Our toppers offer full support during the night, helping you to feel revitalised and well-rested when you wake up.

Affordable Alternatives

Toppers are a simple and cheap alternative to a new memory foam mattress. They enable you to experience the pressure-alleviating benefits, and can instantly transform a sad and somewhat deflated set-up into what feels like a brand new mattress, at a fraction of the cost. A great night’s sleep should be affordable to all, which is something we aim to provide with each memory foam topper.

Prolong the Life of Your Mattress

Even a high-quality mattress needs a certain level of protection. After all, we spend roughly eight hours a night there, so it’s important to give it the care it needs. Please note: a topper won’t feel as comfortable on a dipped or damaged mattress. However, it can act as a mattress protector and help your mattress last longer.

Extra Layer of Comfort

Already have a memory foam mattress? Our toppers are a layer of added comfort that will leave you looking forward to bedtime. As a general rule, the higher the density, the firmer the mattress topper. A higher density will lengthen the rebound time of the foam and the increase in the amount of heat it retains. It will also improve the longevity of your topper and offer an increased level of comfort and pressure relief. 

Suitable for Many Places

From student accommodation to rental homes, a mattress topper is welcome anywhere. They can help alleviate any sleeping space and heighten the sense of luxury.

Do you also wish you could have guests to stay, but you don't have a spare bedroom? Don't worry! You can transform your living room, dining room or kitchen into a comfortable sleep environment with a sofa bed, complete with a memory foam mattress topper to make it feel as comfortable as a memory foam mattress, while also protecting your sofa!

Get the Complete Luxury Sleeping Experience

Whether you've spent some cash investing in your bed setup with plush feather & down duvets or silky sheets and pillowcases but you're still not satisfied, or you're maybe trying to save money but you wish your sleep was a bit more comfortable, we recommend trying one of our memory foam toppers to complete your sleeping experience.

Mattress Topper or Mattress Protector; Which is Best?

The main purpose of a mattress protector is to keep your mattress as hygienic and clean as possible. Mattress protectors shield your mattress from body oils, sweat and general spillages, leaving you with a clean and unspoiled mattress - perfect for hot sleepers or clumsier individuals who already love the comfort of their existing mattress. 

On the other hand, memory foam mattress toppers are best for individuals more worried about their comfort levels or health while sleeping. While a mattress topper can protect your mattress from excess oils and sweat, its primary aim is to offer extra comfort and support to your body; it's the best of both worlds. Mattress toppers can also help with night sweats, as some are built with cooling, temperature regulating properties.

You can put a mattress protector directly into your washing machine to give it a good clean whenever you need, whereas a mattress protector should come with a machine washable cover that you can simply unzip and wash with your weekly laundry. 

Complete Your Collection

It’s not just memory foam bed toppers that can give you the good night’s sleep you deserve!


Our memory foam pillows are the ideal surface to rest your head on at night. They offer vital support for your neck and spine, ensuring everything is aligned and reducing aches or pains. They mould to your head shape, helping you stay in the position most comfortable for you. This not only cradles you but has medical benefits, such as improved blood circulation.

Beds and bed frames

Your bed frame itself can play a significant role in how refreshing your night’s sleep is. The key is to combine comfort with practicality. We’ve found the best bed frames are those that offer support and prevent mattress sagging. Ensuring the slats aren’t too far apart is one tip. Our brands include:
