Finding the right memory foam mattress can be a challenge, especially when you’re comparing top contenders like the Dormeo Memory Plus Mattress and the Silentnight 7 Zone Memory Mattress. Both are customer favourites in the UK, aiming to deliver exceptional comfort, pressure relief, and all-over support without breaking the bank. But which one fits your needs and sleep preferences best?
Meet the Contenders: Dormeo vs Silentnight
Before diving into features and differences, let’s briefly introduce both mattresses.
Dormeo Memory Plus Mattress
The Dormeo Memory Plus is a medium-firm memory foam mattress designed to balance pressure relief and spinal support. It’s part of Dormeo’s bestselling Original range and suits a wide range of sleepers. Recognised for its comfort and value, it’s become a household name for those seeking an affordable foam-only mattress.
Silentnight 7 Zone Memory Mattress
The Silentnight 7 Zone Memory Mattress is a memory foam mattress known for its zoned support system. As a trusted British sleep brand, Silentnight offers this mattress to meet the needs of sleepers seeking extra ergonomic support. Its standout feature is the seven targeted support zones which claim to promote healthy spinal alignment and minimise aches.
Comparing Construction and Materials
What’s Inside the Dormeo Memory Plus?
The Dormeo Memory Plus features a two-layer construction:
- 2.5cm of high-density Dormeo memory foam as the comfort layer
- Core of 14cm Ecocell® foam for support, breathability, durability
This combination offers body-moulding comfort, pressure relief, and a supportive base. Ecocell foam’s open cell structure aims to improve airflow, reducing heat build-up.
What’s Inside the Silentnight 7 Zone Memory Mattress?
Silentnight take a slightly different approach:
- 2.5cm comfort layer of memory foam
- Zoned Miratex foam core (total mattress depth around 18cm) with seven distinct areas engineered for head, shoulders, spine, hips, knees, legs, and feet
The zoned design aims to offer firmer support where you need it, and softer cushioning elsewhere.
Comfort and Feel: Firmness Levels
Dormeo Memory Plus Mattress Feel
This Dormeo mattress is rated as ‘medium-firm’. The memory foam surface feels comfortably soft as you first lie down, adapting to your body shape and then settling into reliable support. Most UK sleepers find it strikes a good balance – not too hard, not too soft – and is suitable for back and side sleepers. Stomach sleepers looking for extra support may prefer something firmer.
Silentnight 7 Zone Memory Mattress Feel
The Silentnight mattress is also classed as ‘medium-firm’. However, the zoned support can make certain areas feel firmer or plusher depending on body position and weight. This is ideal for those who toss and turn, need extra lumbar support, or share a bed with a partner of a different body type.
Who Are These Mattresses Best For?
Dormeo Memory Plus Suitability
Dormeo Memory Plus works well for:
- Sleepers who enjoy a classic memory foam ‘hug’
- People seeking a cool foam mattress (thanks to Ecocell’s airflow)
- Most sleeping positions except strict stomach sleepers
- Allergy sufferers (hypoallergenic, dust mite resistant)
- Budget- and eco-conscious buyers (often on sale)
Silentnight 7 Zone Memory: Who Will Benefit?
The Silentnight 7 Zone Memory Mattress tends to suit:
- Sufferers of specific pressure points, back pain, or posture needs
- Anyone sharing with a restless partner
- Combination sleepers who move during the night
- People seeking a recognised, trusted UK brand

Temperature Regulation: Keeping Cool
A common concern with memory foam is overheating. Both mattresses take steps to improve airflow but approach the problem differently.
Dormeo’s Ecocell base foam is especially engineered for breathability, with an open-cell structure. Many customers report it sleeps cooler than standard memory foam – though very hot sleepers might want to look at mattresses with specific cooling tech.
Silentnight uses a lighter foam base and a soft knit Purotex cover to help with airflow. Their design is simple and relies on the relatively shallow comfort layers to minimise heat build-up. Neither is at the cutting edge for cooling, but both perform well for all but the warmest of sleepers.
Support for Back and Joint Pain
If targeted support is a priority, the Silentnight 7 Zone’s zoning wins points. Its variable-density foam gives firmer pushback at the lumbar region and shoulders. This zoning can help to maintain better posture and alleviate tension across the spine. If you suffer from aches, pains, or want extra ergonomic shaping, you may benefit more from zoned support.
The Dormeo Memory Plus is no slouch for pressure relief – the memory foam contours to joints, and the Ecocell foundation holds you in healthy alignment. For most sleepers, it’s a comfortable all-rounder, but those with chronic back pain may still prefer the Silentnight’s zoning or a more specialist orthopaedic mattress.

Motion Isolation: Sharing the Bed
Both mattresses are great for reducing motion transfer – a hallmark of quality memory foam. Most reviewers report that partner movement is barely felt, making them ideal for couples or light sleepers. Neither contains springs, so there’s little ‘bounce’ or ripple.
Edge Support: Sleeping to the Edge
Edge support with both the Dormeo Memory Plus and Silentnight 7 Zone Memory can sometimes be lacking, as is common with many foam-only beds. If you regularly sit or sleep close to the edge, you may notice more sinkage compared with an innerspring or hybrid mattress. That said, for most sleepers, support remains even across the entire sleeping surface.
Allergy and Hygiene Benefits
Both mattresses come with hypoallergenic covers for allergy-sufferers. Dormeo’s anti-bacterial treated cover is removable and washable. Silentnight’s Purotex cover has probiotic treatment to help reduce allergens and keep the mattress feeling fresh. This is little surprise, as both brands frequently appear in UK allergy-friendly mattress guides.
Practicalities: Delivery, Setup, and Guarantees
The Dormeo Memory Plus is delivered vacuum-packed and rolled up, making it easy to manoeuvre to your bedroom. Once opened, it expands to full size in a few hours. Dormeo offers a 60-night comfort trial, giving you peace of mind.
The Silentnight 7 Zone Memory Mattress is also delivered rolled, making upstairs access easy. Set-up is simple – just open, unroll, and allow it to expand. Silentnight tend to offer a slightly shorter trial period, depending on the retailer.
Dormeo provides an industry-leading 15-year warranty. Silentnight’s is typically five years, but both comply with UK safety and quality standards.

Sizes and Pricing
Both mattresses come in standard UK sizes: single, small double, double, king, and super king.
Pricing fluctuates due to frequent offers. At full price, the Dormeo Memory Plus tends to be slightly more expensive, but sales and bundle deals are common. Silentnight is often rated one of the UK’s best value memory foam options at its RRP.

Which Mattress Will Last Longer?
The longevity of a mattress depends on daily use, weight of sleepers, and care. Dormeo’s 15-year warranty signals confidence in its durability, with many owners reporting comfortable sleep for 8–10 years. Silentnight’s 7 Zone Memory, backed by a solid five-year warranty, is also built to last, typically holding up 5–8 years before any noticeable sagging.

Customer Reviews and Real-World Feedback
Dormeo Memory Plus regularly receives praise for comfort levels, especially for side sleepers. Households comment on transformative support and excellent pressure reduction. Reviewers enjoy its quick set-up, cool feel, and notable improvement in sleep quality at this price point. Some mention a slight odor (“off-gassing”) after opening, but it dissipates quickly.
Silentnight 7 Zone Memory gets top marks for its supportive, zoned feel, with positive comments about easing back and hip pain. Many owners choose Silentnight for brand trust and customer service. Some find it feels a little firmer than expected, but still agree it delivers restful sleep.
