The Panda mattress topper is one of our favourite budget-friendly toppers available in the UK.

It is made of a gel-infused memory foam (called Hydro-foam™), specifically designed with open-cell cooling technology and heat-sensitive capsules that react to your body temperature to keep you cooler than traditional memory foam.

The memory foam also allows for orthopaedic support and can help relieve neck, back, and hip pain.

The bamboo topper cover is soft and naturally breathable and is machine-washable up to 40℃. 

The topper features an anti-slip layer and elastic corner straps to keep it firmly in place.

The Emma Flip Topper has a unique dual-sided design with two foam layers.

These are:

  • Comfort side: Airgocell foam

This makes the Emma mattress topper a great option for sleepers who need a little more variety or are unsure whether they need more softness or firmness.

  • Machine-washable cover

Tell me more about the Hypnia topper

The Hypnia Ultimate mattress topper provides a deep layer of comfort to your current mattress. 

Designed to relieve pressure, the memory foam technology works wonders in aligning the body and reducing tension in the lumbar region or neck.

The Hypnia topper has a soft and absorbing feel, gently hugging around the body like you're sinking into a marshmallow. 

It has a non-slip base designed to keep it secure on the mattress throughout the night.

However, the extra-deep topper sometimes slid off the bed during testing, so we would favour a design with straps for increased stability.

Its ultra-breathable cover promotes ventilation and is machine-washable, which is great for those that sweat during sleep. 

Reasons to buy

OEKO-TEX STANDARD 100 certified

What is a mattress topper?

A mattress topper goes on top of the mattress, adding a layer of comfort and extra support.

people relaxing on mattress topper
A mattress topper is an extra comfort layer for your mattress.

It can improve and change the feel of your current mattress that doesn't feel comfortable.

A memory foam mattress topper can even soften the feel of a new mattress that is too firm. 🧸

Are memory foam toppers any good?

Memory foam is arguably the best material for a mattress topper. 👑

Perhaps we’re biased - but memory foam has a blissful, cloud-like feeling that no other material can replicate.

But how does it work?

Memory foam responds to the heat and pressure of the body. 🌡️

The images below show you how this works:

memory foam returning to shape

Memory foam is made of unique viscoelastic cells, which adapt to your body shape under heat and pressure.

This helps to alleviate stress on crucial pressure points such as the shoulders and hips, promoting healthier sleep patterns and reducing the likelihood of waking up with aches and pains.

Once you remove the pressure, like when you get up, the foam gradually returns to its original shape.

Do I need a mattress topper?

Let’s face it - it’s not easy finding the perfect mattress. 🤔

Check this list to see if any of the following apply:

  • Your current mattress is too firm or soft
  • You want a warmer or cooler sleep
  • You need extra pressure relief on your shoulders, hips, or knees
  • You want to increase the comfort of a temporary bed (i.e. sofa bed, fold-out bed, or even the floor!)
  • You want to improve the lifespan of your mattress
  • You want to add some extra depth to a thin mattress
  • You find an exercise mat or yoga mat too firm and are looking for a soft alternative.

If you said yes to any of these, a memory foam mattress topper could be an excellent investment.

Whatever your reasoning, a memory foam mattress topper may be able to provide some better comfort to your lifestyle.

We’ll go into more detail below. 👇

Which memory foam mattress topper is best for me?

Most memory foam mattress toppers will provide pressure relief, support and enhanced comfort to your sleep. 😍

But some memory foam toppers have specific features that make them suitable for different criteria.

So, which memory foam mattress topper can solve your sleep dilemma? 🧐

Can a memory foam mattress topper make my mattress softer?

A memory foam topper can certainly soften the feel of most mattresses.

Memory foam is soft and body-hugging, like sleeping on a cloud.

A memory foam topper moulds around sensitive areas and relieves pressure.

This makes them ideal for side sleepers who need to sink more into their mattress.

The Hypnia Ultimate mattress topper is one of the softest and most luxurious memory foam toppers. ✨


This thick memory foam topper helps provide pressure relief to the hips and shoulders.

Can a memory foam mattress topper make my mattress firmer?

Memory foam comes in various densities and reacts to the body differently. 👀

Some memory foam mattress toppers use firm-feeling foam, which can provide support to a soft mattress.

A memory foam topper can provide additional support for your sleep.

This helps to prevent the spine from bending and keep it in a neutral alignment.

Memory foam toppers tend to be soft, so if you're looking for a firm topper, consider alternatives.

The Simba Hybrid topper comprises Simba-Pure foam and pocket springs, giving it a medium-firm feel.


We tested this mattress topper ourselves and found it made our mattress feel much firmer and more stable. 🧱

Memory foam retains heat during the night.

Memory foam is one of the warmest materials.

Therefore, it’s an excellent material for those looking for a warmer sleep. 🔥

Memory foam stores heat up from the body, warming up any surrounding material.

Most memory foam mattress toppers will help to keep you warm and cosy during colder months. ☃️

Can a memory foam mattress topper make me feel cooler?

Some memory foam toppers come with cooling technology. ❄️

Some memory foam toppers have unique cooling abilities.

A cool mattress topper can help to encourage better temperature regulation in your sleep.

The Panda mattress topper uses gel-infused cooling technology and a natural moisture-wicking bamboo cover.

This combination provides a breathable layer of comfort for a cooler sleep. 🌬️


However, if you’re typically a hot sleeper, you should probably avoid memory foam altogether. 👎

Instead, consider natural toppers made with latex, cotton or wool.

How much do memory foam mattress toppers cost?

Prices for memory foam mattress toppers vary from budget to high-end. 💰

Memory foam mattress toppers can be cheap or expensive.

Cheap memory foam mattress toppers are typically thinner and less effective in providing enhanced comfort to your sleep.

We recommend spending that little extra on a high-quality product that is great value for money.

The Panda mattress topper is fantastic quality yet affordable. 🙌

How do I attach a memory foam mattress topper?

A mattress topper sits on top of your mattress - but how does it stay there?

This may be a concern if you’re a particularly fidgety sleeper. 🤸‍♂️

Luckily, most mattress toppers come with straps on each corner or an anti-slip base on each corner.

This helps the mattress stay in place to avoid disrupting your sleep.

Your mattress protector and fitted sheets will also help keep the topper fixed in place.

We recommend a mattress protector made from natural fibres for memory foam toppers, which will encourage temperature regulation.
