Soft knit micro-quilted cover
Breathable, stretchy soft knit outer with micro-quilted finish. Hypoallergenic construction for a cleaner, healthier sleep environment.
2
UltraGel comfort layer
Silentnight's advanced gel-infused foam, engineered with an open-cell structure to be five times more breathable than standard memory foam. Unlike traditional memory foam which holds the body's impression, UltraGel has a highly responsive structure that bounces back immediately as you move - ideal for combination sleepers who change position. The cooling gel draws heat away from the body, actively regulating temperature throughout the night. Pressure is distributed evenly across the surface, relieving hotspots at the hips, shoulders and joints.
3
Breathable mesh border
A ventilated mesh border runs around the full perimeter of the mattress, providing an additional airflow pathway to complement the UltraGel layer above - helping warm air to escape and keep the mattress fresh.
4
Zoned Mirapocket springs - 1,000
1,000 individually nested Mirapocket springs, each held under tension in its own fabric pocket and responding independently to body weight and movement. Zoned support promotes healthy spinal alignment across all sleeping positions and minimises motion transfer for undisturbed rest.
Best suited to
Back, side and combination sleepers - medium firm suits all positions
Hot sleepers - UltraGel is 5x more breathable than standard memory foam
Combination sleepers - UltraGel bounces back immediately on position changes
Allergy sufferers - hypoallergenic construction
Couples - 1,000 individual pocket springs minimise partner disturbance
Those wanting gel comfort without the slow-response feel of memory foam

Comfort Rating
Med/Firm

A medium-firm mattress is a level of firmness that is slightly firmer than a medium mattress but still has a moderate amount of "give". A medium firm mattress is extremely comfortable. It's perfect if you want a little extra support but still, like your bed to feel cosy and soft.

Guarantee
5 Year

One year year guarantee followed by a four year sliding warranty.
The product comes with a 1 year guarantee that covers any defects in materials or workmanship during the first year after purchase. After the first year, the guarantee transitions into a sliding warranty where the coverage decreases gradually over the 4 year period and the customer would need to contribute a increasing percentage of cost to the repair based on the age of the item.

Mattress Cover
Knitted

Knitted fabric is typically used as a top layer on a mattress as it provides a soft, breathable, and stretchy surface.

Mattress Core
Pocket Springs

Pocket springs are made by individually wrapping each spring in a fabric pocket. This design allows the springs to work independently, providing more support and reducing motion transfer. A great choice if you're looking for a mattress with balanced comfort and support.

Memory Gel

Memory gel is a combination of gel and memory foam, which creates a material that is both supportive and comfortable. Additionally, many memory gel products are designed to be breathable and moisture-wicking, which can help to regulate temperature and prevent overheating during sleep.

Mattress Surface
MicroQuilted

A micro quilted mattress cover is a type of mattress cover that has a quilted design on its surface. The quilted design is made by stitching together the top layer of the mattress cover to the bottom layer, with a layer of padding in between. This creates a raised, textured pattern on the surface of the cover.

Turnable
Single Sided

A single sided mattress is designed to be used only on one side.

Features
Keeps You Cool

Helps regulate body temperature and prevents overheating by improving breathability, airflow, and heat dissipation

Reduces Partner Disturbance

Perfect for couples, as movement on one side won’t disturb the other.

Pressure Relieving

Pressure-relieving mattresses are designed to distribute the body's weight more evenly across the surface of the mattress, reducing pressure on specific points such as the hips, shoulders, and spine. This can help to alleviate discomfort and pain and promote better circulation and more restful sleep.

Ideal for All Sleeping Positions

Offers balanced support, whether you sleep on your back, side, or stomach.

Higher Weight Support

Provides strong support, durability, and pressure relief.

No Roll-Together

Each spring moves independently, preventing sagging or dips over time.

Hybrid Support

A hybrid mattress offers the best of both worlds, the pressure relief and contouring of foam with the responsiveness and support of springs.

Extra Support & Spinal Alignment

The Individual pocket springs move independently, adapting to your body's contours which creates targeted support, reducing pressure points on the back, neck, and joints.

Excellent Temperature Regulation

Absorbs and wicks away moisture, preventing overheating, helping to keep you cool in summer and warm in winter.

Pocket Spring Count
1000

    My partner is a tornado in their sleep and our old mattress transferred every movement. The pocket springs in this mattress are a gamechanger. I genuinely dont feel them tossing and turning anymore. The motion isolation is incredible. Were both sleeping through the night which has made a huge difference to our energy levels and mood.

    This is a very good mattress but its not as firm as I expected from the description. The gel topper adds a significant plushness that while comfortable might not be ideal for someone who needs a truly firm orthopaedic surface. It provides great support but the initial feel is softer than Id like. A 4star rating for me but a 5star for most people.

    Its the perfect balance of softness and support. You sink in just enough to feel cradled but theres no stuck feeling. The gel layer provides a lovely plush top while the springs stop you from sinking too far. Its neither too hard nor too soft its just right. I look forward to going to bed every single night.

    Ive suffered from lower back pain for years cycling through mattresses with no luck. The UltraGel 1000 has been a revelation. The combination of firm support from the 1000 pockets and the gentle cushioning of the UltraGel layer means my spine is perfectly aligned all night. I wake up feeling truly rested and for the first time in a long time without any morning stiffness. Worth every penny.

    As someone who usually sleeps hot I was skeptical about the UltraGel cooling claims. Im happy to report it genuinely works! The mattress surface stays noticeably cooler throughout the night. It doesnt feel cold to the touch just neutral which prevents that sticky overheated feeling. Combined with the excellent support its the best sleep Ive had in summer.
