What Is an Extra Thick Mattress Topper?
An extra thick mattress topper is a padded layer placed on top of your existing mattress to add height, softness, or support. Thickness generally ranges from about 5 cm to 10 cm, with the most common options around 6 cm to 8 cm. The extra loft can enhance pressure relief for hips and shoulders and can improve overall spinal alignment by distributing body weight more evenly.
Materials vary, including memory foam for contouring, gel-infused foams for cooling, latex for bounce and resilience, and hybrid blends that combine foam with springs. A removable, machine-washable cover often accompanies these toppers, making cleaning easier and protecting the topper from wear.
What Are the Most Popular Types of Mattress Toppers?
Memory foam toppers respond to body heat and weight, creating a personalized cradle that relieves pressure points. Gel-infused memory foam helps dissipate heat for cooler sleep. Latex toppers offer natural resilience and durability, with a buoyant feel that some sleepers prefer. Wool or bamboo-infused toppers provide natural breathability and moisture-wicking properties for a cooler night. Hybrid toppers combine foam layers with a supportive core or micro-coils to balance softness with stability.
There are also feather or down-alternative toppers for a plush, luxurious feel, often with a hypoallergenic inner fill. Covers vary from cotton blends to microfibre fabrics, with some being breathable/knit fabrics designed to maximize airflow and reduce heat buildup during sleep.
How to Choose the Right Thickness and Material?
Think about your current mattress and sleep priorities. If you sink too deeply into a worn-out mattress, an extra thick topper in memory foam or latex can restore contour and support without replacing the bed. If you sleep hot, look for gel-infused or breathable covers and materials with good airflow. For couples, a topper with good motion isolation helps minimise partner disturbances.
Thickness matters: 5 cm to 6 cm can add noticeable cushioning for most sleepers, while 7 cm to 10 cm is ideal for those wanting substantial loft and pressure relief. In general, go for a slightly softer feel if the topper sits on a firmer mattress, and choose a firmer topper if your mattress is already soft or worn. Always verify the product’s weight capacity, density, and warranty to ensure lasting comfort.
Also consider the cover: a removable, washable cover protects the topper and makes hygiene simpler. Look for anti-slip bases or corner straps to keep the topper in place on various mattress depths.
How to Maintain and Clean an Extra Thick Mattress Topper?
Regular vacuuming removes dust and allergens, while spot-cleaning spills promptly protects the topper’s integrity. If the topper has a removable cover, follow the care label instructions for washing, usually machine wash on a gentle cycle and air dry to preserve foam integrity. Avoid harsh detergents and high heat, which can degrade foams and fabrics over time.
Rotating the topper every few months helps prevent uneven wear and prolongs comfort. If you notice persistent sagging or lumping, it may be time to replace the topper or pair it with a more supportive mattress upgrade. Proper care ensures your investment continues to deliver restful nights for longer.
Keep your sleeping environment fresh with our range of extra thick mattress toppers at Wowcher UK, designed to be durable, easy to maintain, and compatible with a wide range of bed frames and mattresses.
What Sizes Are Available and How Do I Fit It?
Sizes commonly range from twin and double to king and super king. Always measure your mattress depth and check the topper’s fit guidelines, since some toppers require a snug fit to avoid slipping. If your mattress depth falls between standard sizes, choose a topper that offers a slightly larger cover or adjustable corners. Most toppers come with corner bands or elastic edging to help secure the topper in place.
If you have a heavy mattress or a unique frame, be sure to confirm compatibility with our product descriptions and sizing guides. With the right size and thickness, an extra thick mattress topper can transform a basic bed into a luxurious retreat.
What Are the Health and Comfort Benefits?
Pressure relief is a key benefit, helping to reduce pains in the shoulders, hips, and back by distributing weight more evenly. Improved alignment can contribute to fewer waking moments during the night and a more refreshing morning. If you suffer from allergies or asthma, many toppers use hypoallergenic fillings or breathable covers that resist dust mites and microbes, supporting cleaner sleep environments.
For hot sleepers, gel-infused or breathable materials can improve cooling, while memory foam with higher density offers lasting support. A well-chosen extra thick topper can also extend the life of your existing mattress by adding a protective layer against wear and indentations.
How to Install and Use an Extra Thick Mattress Topper?
Unbox the topper and check for any packaging or odor. If your topper has a memory foam scent, it typically dissipates within a day or two in a well-ventilated room. Place the topper on your mattress with the cover facing up. Secure any corner straps or anti-slip features. If your bed uses a fitted sheet, ensure the topper remains aligned as you smooth out wrinkles. Regularly rotate the topper to keep wear even and maintain balanced comfort across the sleeping surface.
For best results, pair your extra thick topper with a suitable pillow system and a breathable duvet. This combination can amplify comfort, reduce heat buildup, and help you enjoy more restorative sleep night after night.
