A wonderfully supportive mattress featuring 800 responsive Mirapocket springs and breathable, sustainable Eco Comfort Fibres™.

Silentnight's innovatively designed pocket springs are scientifically proven to respond to your unique shape. The zoned springs enhance spinal alignment, posture and pressure relief.

Silentnight's innovative eco-friendly fibres offer an ethically sound slumber. These fresh and comfortable fillings are made from recycled materials and kind to our environment.

Firmer than a medium mattress for extra support

About 10.2 inches deep. Depth is an important factor when buying a mattress as it can affect the suitability for particular bedding, mattress toppers and bed frames.

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!

For your ease of mind, vegan-friendly mattresses contain no animal derived materials. Sleep in peaceful assurance, knowing it is not manufactured in the same space as natural fibres.

Free from harsh chemicals or irritants or allergens, this product is treated with a natural fire retardant formula. Better for you and the environment.

For your peace of mind

Expertly handcrafted in the UK. This product helps to support our economy and helps to reduce environmental impact.

For the highest standards of quality and safety
The Silentnight 800 Mirapocket Mattress is a wonderfully supportive mattress with a medium to firm feel.
Springy, zoned support
800 individual Mirapocket springs are zoned to provide relief to key points such as the back, joints and hips. As well as responding to your body's unique shape to provide personalised support, these springs absorb movement to minimise disturbance during the night. An excellent choice for couples!
Cosy and sustainable
As well as this excellent spring system, this mattress includes a comfort layer of Silentnight's Eco Comfort Fibres™. Eco Comfort Fibres™ are developed both from sustainable materials and repurposed plastic to create a layer which is comfortable and dreamy to sleep on. Eco Comfort Fibres™ are also highly breathable, allowing air to circulate more freely in the mattress for a fresher overall feel.
Fine finishes
This mattress features a soft-touch, knitted cover. It's hypoallergenic and free from foam and chemical treatments for a naturally healthier sleep.
Just keep turning
It's single-sided, meaning there is no need to turn it over. However, we recommend rotating the mattress every three months for equal wear.
Quality guaranteed
As one of the first B-Corp certified sleep brands, Silentnight have proven why they are the UK’s most trusted name in sleep. Their commitment to quality and environmentally responsible practices ensures a better night’s rest and a brighter future for you.
It is made in the UK and is also covered by Silentnight's 5 Year Guarantee, meaning you can buy with complete peace of mind.

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.
