Experience ultimate comfort with the Simba Hybrid Ultra 7300 Pocket Mattress. The luxurious blend of Simbatex® foam and pocket springs provides unstoppable support.

Individualised springs encased in cloth pockets. Expertly adapting to movement to distribute personalised support to each part of your body.

Small, individually cased springs provide added comfort to the mattress whilst offering soothing pressure relief. Mini springs decrease motion transfer so you can share the bed undisturbed.

Memory foam creates a cushioned feel by cradling to your unique shape. Enhancing the remarkable comfort, the foam has a sumptuous feel, delivering a cosy sleep.

Stay snuggly all night long. Perfect all year round, wool is a natural insulator and has great temperature regulating properties.

A plush, adaptive material that responds to your body shape for individualised, ideal comfort. Latex actively responds to your body throughout the night for a truly revitalising slumber.

Naturally hypoallergenic, bamboo fights against allergens and creates a dust mite free space for a cleaner environment.

A rolled-up mattress is efficiently packaged for easy manoeuvring. Because of its smaller, compact design, less delivery vans are needed, providing a great environmentally-friendly option.

Offering a soothing night's rest by evenly distributing your body weight across the mattress. The pressure point relief provides the ultimate relaxation needed for a deep slumber.

A sumptuously soft finish that provides additional cosiness and warmth. Knitted covers enhance airflow and are incredibly breathable. So, you can enjoy a cooler snooze.

Removable covers are convenient and keep mattress maintenance simple. Easily remove the cover and wash to preserve the mattress quality.

Enjoy the feeling of a crisp, fresh mattress with a washable cover. It renews the freshness of your bed with ease for a hygienic and healthy rest.

With a single-sided mattress, there's no need to flip. Simply rotate every few months to care for your mattress. Fuss free mattress maintenance!

Free of allergens for a cleaner, healthier sleep. No allergenic materials were used so you can enjoy an undisturbed rest without the risk of allergy reactions or respiratory problems.

Natural touch
Simba’s FusionCool™ layer features a special blend of wool, bamboo, charcoal and kapok. The mixture of these fibres provide optimal breathability, allowing air to flow through these fibres. The enhanced airflow creates a cooler sleeping environment, so you can enjoy an undisturbed rest. The addition of kapok allows this layer to be fully moisture resistant for a fresher sleep.
Cushioning comfort
Sticking to their roots, this mattress isn’t excluded from their own unique memory foam technology. It includes two layers of Simbatex® foam, which is designed to provide soothing pressure relief, easing built-up pressure, aches and pains. Simba’s special foam increases the elasticity and cushioning through the mattress so you can experience sumptuous comfort.
Enhanced support
With the clever blend of latex and coconut, you can expect incredible bounce-back. The mixture of elastic latex and breathable coconut fibres in their PureLift™ equal to great pressure distribution. Latex is known for its enhanced elasticity, it’s an expert at soothing those pesky aches and pains. Enhancing the pressure relief to the maximum, it’s designed to adapt to your body shape for exceptional support.
Springs in abundance
The base of the Simba Ultra is made up of a SupportCore™ that features 1000 traditional pocket springs. These springs fully support your body as they actively react to your shape, providing personalised support and reduced motion transfer. The springs are constructed right to the very edge, ensuring a strong border and edge-to-edge support.
Nestled just above the SupportCore™ are 2500 high carbon steel Aerocoil® micro springs. Placed there to maximise the support given by the traditional springs. These micro springs also gently push around fresh air as they compress, helping to increase airflow.
3800 titanium alloy Aerocoil® micro springs are sat in the upper layers, supporting the pressure relief properties and actively responding to your body as you sleep.

This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

Natice firm, extremely deep, very well-made, replaced a rival product that was only 2 years old and don’t regret my decision so far. Much easier to turn over in bed now.
