The top layer of our Guru mattress is made from 4G Air Memory Foam which provides all the luxurious comfort and support of traditional foam with some added extras.

4G Air memory foam releases a cooling sensation when pressure is applied so you never have to worry about feeling too warm. The open-cell structure of the memory foam allows the mattress to naturally air itself, maintaining a clean and fresh sleeping space.

Is This the Right Bed for You?

A mattress guide can help you determine the right choice for your individual situation. Remember, what might feel comfortable to someone else may not feel the same to you!

Some advice is always to consider your personal preferences. For example, those who sleep on their stomach should look for firm support.

If you want to try before you buy, head down to our mattress outlet shop in Wakefield, where you can find many different products.

What Makes Memory Foam the Perfect Material?

This material is held in high esteem across the globe – earning huge popularity for good reason. It’s not just comfort levels it offers – although rest assured you’ll find one of the most luxurious surfaces money can buy. However, this foam has a number of health benefits that shouldn’t be overlooked.

Spine Alignment

It’s hugely important to keep your neck and spine aligned while you sleep. This reduces aches and pains, ensuring you wake up feeling refreshed.

Full Body Support

A mattress that’s broken or sagging won’t offer adequate support – therefore it’s vital you change yours. Memory foam can hold every area of your body individually, from hips to shoulders, giving you the feeling of floating.

This can also significantly reduce motion transfer, making sure you won’t feel your partner move as they sleep. This is particularly important if there’s a notable weight difference between the two of you.

Air Circulation

Tired of getting hot and bothered at night? Your current mattress may not be allowing air to circulate, causing you to overheat.

Pressure Point Relief

Are there any specific points of pain on your body? Your mattress could be aggravating them without you realising. Memory foam can provide the relief you’re looking for.

This doesn’t just apply to pressure points. This material can also relieve you of strain and stiffness, while easing muscle pain simultaneously.

Allergy Relief

If you suffer from allergies, your mattress could be making these worse, without you realising.

For example, particularly if you’re prone to overheating at night, dust mites can build up and cause a number of symptoms, such as sneezing. The result? A restless night’s sleep.

Memory foam can help alleviate this – ensuring the surface you sleep on leaves you feeling rejuvenated.

How to Set Up Your Bed in a Box

Unboxing couldn’t be simpler – but to ensure you do it right, here’s a step-by-step guide:

Open the box
Remove the rolled mattress with the protective packaging still intact
Place it on the bed it’s intended for
Open the packaging (ideally without the use of scissors just in case you damage the product)
Unroll the mattress
Give it time to expand and regain its original shape (at least 24 hours)

After that, your mattress in a box is ready to use – it’s as easy as that!

What Sizes Does This Product Come In?

We believe variety is key – which is why our mattress in a box comes in multiple sizes. These include:

King size
Super king size

This ensures you aren’t limited, you can find everything you’re looking for – regardless of the dimensions you require.
