Choosing memory foam mattresses with extra thickness can improve durability, reduce wear over time, and enhance lasting comfort. Browse top-rated brands, sleep trial options, and straightforward warranties, all designed to help you save while upgrading your sleep experience.
What to Consider When Choosing an Extra Thick Memory Foam Mattress?
First, think about your preferred firmness. Extra thick memory foam mattresses come in a range from medium to firm to support spinal alignment for back and stomach sleepers, while still offering cushion for the shoulders and hips for side sleepers.
Next, assess cooling features. Look for gel-infused memory foam, open-cell structures, and breathable covers that help dissipate heat, especially if you sleep hot or share a warmer room.
Material quality matters. High-density memory foam (often 4 lb/ft³ and above) tends to be more durable, reduces sagging, and improves motion isolation, ideal for couples and restless sleepers.
Sizes and compatibility are essential. UK customers typically shop in single, small double, double, king, and super king. Ensure your base and bed frame will support an extra thick mattress without gaps or bending that could affect comfort.
What Are the Most Popular Types of Extra Thick Memory Foam Mattresses?
Gel-infused memory foam mattresses combine cooling properties with contouring support, helping you stay comfortable through the night. Lucid, open-cell memory foam layers promote airflow and a plush feel without sacrificing support.
Hybrid options blend memory foam with pocketed springs for additional bounce, even weight distribution, and enhanced edge support, making them a good option for couples who want both ease of movement and deep contouring.
How to Maintain an Extra Thick Memory Foam Mattress?
Rotate the mattress every 3–6 months to promote even wear, and use a breathable mattress protector to defend against spills, allergens, and dust mites. Avoid standing on the mattress or folding it, as excessive bending can damage the memory foam layers.
Spot clean spills promptly and use a mild detergent on the protector cover. Air the mattress occasionally to keep it fresh, and follow the manufacturer’s care guidelines for your specific model.
Keep your sleep space comfortable and hygienic with our wide range of extra thick memory foam mattresses. At Wowcher UK, you’ll find everything you need to refresh your bedroom with ease and efficiency.
What Is the Right Thickness for My Sleep Needs?
“Extra thick” typically refers to mattresses from about 6 inches (15 cm) and up. Heavier sleepers may benefit from added thickness and higher-density foam for better support and longer-lasting shape retention, while lighter sleepers might still enjoy comfort with slightly thinner options.
If you have shoulder or hip issues, thicker layers can provide greater pressure relief and maintain spinal alignment. Always match thickness with your weight, preferred firmness, and sleeping position for optimal results.
How Do I Choose the Right Size and Frame for an Extra Thick Memory Foam Mattress?
Measure your bed frame and ensure the chosen UK size (twin, double, king, super king) aligns with standard mattress dimensions. A robust bed frame or slatted base with solid centre support helps prevent sagging and protects the mattress structure over time.
Consider whether you want a pillow-top attachment or a top layer that can be separated for rotating or cleaning. Some models offer removable, washable covers for easier maintenance and upgraded hygiene.
What About a Trial Period or Warranty on Wowcher Deals?
Many Wowcher offers on memory foam mattresses include a sleep trial period, often ranging from 90 to 120 nights, so you can test the mattress in your own bedroom and adapt to your comfort needs. Warranties typically cover manufacturing defects for 5–10 years, giving you peace of mind with your investment.
Be sure to read the terms: return eligibility, condition requirements, and whether bed accessories (like bases and toppers) are included in the deal. Our listings clearly highlight included items, delivery options, and after-sales support to help you shop confidently.
What Are the Best-Selling Brands for Extra Thick Memory Foam Mattresses in the UK?
Top-rated brands on Wowcher UK include models with high-density memory foam, supportive bases, and cooling technologies. Look for reputable labels that emphasize durability, pressure relief, and hypoallergenic materials to suit sensitive sleepers and allergy sufferers.
Read customer reviews, compare density ratings, and check for hybrid options if you want a balance of contouring support and a more responsive feel. Our listings highlight the best combinations of comfort, value, and long-term satisfaction.
