Discover deep, restorative sleep with our exclusive selection of Thick Memory Foam Mattress deals on Wowcher UK. Engineered to cradle your body while delivering solid support, these mattresses blend luxury comfort with everyday value.


Whether you’re seeking relief from pressure points, improved spinal alignment, or a cooler night’s sleep, a thick memory foam mattress can transform your nights. Our Wowcher UK picks feature high-density foams, cooling gel layers, and durable covers designed for longevity and easy care.


From king size for couples to compact options for smaller rooms, you’ll find thick mattresses with edge-to-edge support, motion isolation, and long-lasting comfort. Explore discounts on memory foam mattresses that adapt to your shape while maintaining sturdy base layers for support.


Unbeatable Deals on Thick Memory Foam Mattresses


Our selection includes thick memory foam mattresses with densities from 3 to 5 pounds per cubic foot, premium memory foams, and cooling technologies to help regulate temperature throughout the night. Look for options labeled CertiPUR-US certified for safety and performance.


Whether you want a soft, medium, or firm feel, you’ll find options at Wowcher UK that balance contouring comfort with robust support. Thick profiles often mean enhanced pressure relief for hips and shoulders, plus better edge stability for sitting or getting in and out of bed.


Explore sizes from twin to king, with layered constructions that combine memory foam comfort with a durable base to maintain alignment through the night. If you’re seeking a cooler sleep, look for gel-infused or graphite-infused foams designed to wick heat away.


What to Consider When Choosing a Thick Memory Foam Mattress?


First, assess room size and bed frame compatibility. A thicker mattress upgrade may require deeper fitted sheets and solid foundation to maximize support.


Density matters. Higher density foams (3.5–5 lb/ft³) offer longer-lasting support and better shape retention, especially for heavier sleepers. Lower densities may feel softer initially but break in faster.


Firmness choices are essential. If you’re a back or stomach sleeper, you might lean toward medium-firm to firm profiles. Side sleepers often appreciate a softer feel for targeted shoulder and hip pressure relief.


Cooling and materials make a difference. Gel or graphite-infused foams, breathable covers, and moisture-wicking fabrics help regulate temperature and improve overall comfort during long nights.


What Are the Most Popular Types of Thick Memory Foam Mattresses?


Thick memory foam mattresses with a multi-layer design often combine a comfort layer of 2–4 inches of memory foam with a denser support core. Gel-infused memory foam helps dissipate heat, while graphite-infused foams aid airflow. Some models feature a transition layer to improve spinal alignment and reduce motion transfer for couples.


Edge-to-edge support is common in thicker builds, preventing sagging and making it easier to sit up on the edge. Removable, washable cover fabrics add convenience and hygiene, while warranties give peace of mind for long-term use.


How to Maintain a Thick Memory Foam Mattress?


Regularly rotate the mattress 180 degrees to promote even wear, especially in households with heavier sleepers or couples sharing a bed. Use a sturdy foundation or slatted base that offers uniform support across the entire surface.


Protect the top layer with a breathable, removable cover and wash according to the manufacturer’s instructions. Avoid placing directly on the floor or using harsh cleaners that can degrade the foam over time.


For optimal longevity, keep moisture and pets off the mattress, and ensure your bed environment stays cool and dry. With these care tips, your thick memory foam mattress can maintain comfort and support for years to come.


Keep exploring Wowcher UK for ongoing thick memory foam mattress deals, including king size, queen size, and single options, to suit any room and budget. Our curated collection aims to help you sleep better, wake refreshed, and enjoy true value without compromising quality.


What size thick memory foam mattress should I choose?


Choosing the right size depends on room dimensions, sleeping partners, and how much space you want for movement during the night. For couples, a king or queen size often provides ample space and reduces sleep disturbances from partner movement, while singles may appreciate a full or twin with generous thickness for comfort.


Consider bed frames and foundations; thicker mattresses may require deeper fitted sheets and secure support. If you’re unsure, many Wowcher UK deals show size guides and compatibility tips to help you pick confidently.
