Memory foam mattresses - which one is right for you?

What is a memory foam mattress?

A memory foam mattress is made from a clever material called viscoelastic foam. It softens as it warms with your body heat, then gently moulds to your shape. When you get up, it slowly bounces back, giving you a “hugged by the mattress” feel.

This shaping effect helps spread your weight and ease pressure on areas like your shoulders, hips, and back. That’s why memory foam is often recommended for side sleepers and anyone with aches or joint pain. It also absorbs movement well, so you’re less likely to be disturbed if a partner shifts around in the night.

Many of the best memory foam mattresses in the UK now include cooling features like gel layers or breathable foam to keep you from overheating. Whether you want the best firm memory foam mattress or something softer and more contouring, there’s a memory foam option for most tastes and sleep styles.

What to look for when choosing a memory foam mattress

When choosing the best memory foam mattress, you should consider several key factors to find the right fit:

• Firmness level: Side sleepers often benefit from a softer or medium mattress that cushions shoulders and hips, while back and stomach sleepers may prefer a firmer feel for better spinal alignment.

• Cooling features: Traditional memory foam can trap heat, so look for gel-infused foam, breathable covers, or open-cell technology if you’re a hot sleeper. The best cooling memory foam mattress will combine airflow-enhancing materials with temperature-regulating fabrics.

• Motion isolation: If you share a bed, motion control is important. The best memory foam mattress for couples will minimise movement transfer so you can sleep undisturbed.

• Pressure relief and support zones: High-quality mattresses often include zoned support or orthopaedic features to relieve pressure and support your joints. This is key if you're searching for the best memory foam mattress for back pain.

• Trial period and warranty: Many of the best bed-in-a-box memory foam mattresses offer long trial periods and warranties, letting you test the mattress at home.

• Extras: You may also consider hypoallergenic covers, eco-friendly components, or the best memory foam mattress topper to enhance your current setup without buying a new mattress.

What’s the best memory foam mattress to buy?

The best memory foam mattress depends on your sleep style, budget, and specific needs, like cooling, pressure relief, or motion isolation. That said, for all-round comfort and long-term support, the TEMPUR PRO SmartCool is considered one of the best memory foam mattresses overall. It combines TEMPUR’s signature viscoelastic foam with SmartCool fabric that draws heat away from your body, making it a great choice for hot sleepers or anyone with back pain.

If you’re looking for great value, the Naturalex Cotswold is one of the best budget memory foam mattresses. It offers firm, reliable support and a hypoallergenic design, which is ideal for back or stomach sleepers who prefer a sturdier feel.

If your existing mattress needs a comfort boost, the Panda London Bamboo Memory Foam Topper is a popular alternative. With cooling gel-infused foam and a breathable bamboo cover, it’s one of the best memory foam mattress toppers for adding pressure relief and improving sleep quality without replacing your whole mattress.

How we rate and assess memory foam mattresses

When putting memory foam mattresses through hands-on testing, we assess the criteria that matter most for a comfortable, supportive and restful night's sleep:

• Comfort and pressure relief: How well the mattress contours the body and cushions pressure points such as the shoulders, hips and lower back. We consider how evenly it distributes body weight, whether it feels comfortable over extended periods and how well it suits different sleeping positions.

• Support and spinal alignment: How effectively the mattress helps maintain a healthy sleeping posture. We consider its firmness, responsiveness and ability to support different body weights and sleeping positions, including whether it provides enough support without feeling too hard or ‘sinking’

• Temperature regulation and breathability: How well the mattress manages heat and moisture throughout the night. Old memory foam mattresses were renowned for being too hot, so we consider the breathability of the materials, the use of cooling technologies, and whether it suits people who run warm at night. 

• Motion isolation: How effectively the mattress absorbs movement and prevents movement from transferring across the bed. We consider whether changes in sleeping position or a partner getting in and out of bed are likely to disturb the other sleeper, making this particularly important for couples and light sleepers.

• Materials and overall quality: The quality of the memory foam, comfort layers, support base and mattress cover, including their overall durability. 

• Ease of use and practicality: How easy the mattress is to unpack, position and maintain. We consider its weight, whether it arrives rolled or boxed, any recommended expansion time before use, and the availability of removable or washable covers.

• Firmness and versatility: How accurately the mattress's stated firmness reflects its feel in practice. We consider whether it suits different sleeping preferences, including side, back, and front sleepers, and whether its design balances cushioning and support. Where relevant, we also consider different mattress depths and available sizes.

• Value for money: Whether the mattress's comfort, pressure relief, support, temperature regulation, material quality and practical features justify its price compared with other memory foam mattresses we've assessed. We also consider the guarantee, and trial periods, where available.

We use these assessments alongside long-term tester feedback to decide which memory foam mattresses we recommend and which deserve a Mumsnet Best award.
