What to Consider When Choosing an Extra Thick Mattress?
Size and thickness are your first focus. Extra thick mattresses commonly range from around 25cm to 40cm (approximately 10 inches to 16 inches). The thicker the mattress, the better the distribution of body weight and reduced pressure points for many sleepers. Consider your bed frame height and whether you want a substantial profile that sits higher on the bed.
Support and comfort layers matter. Look for combinations like memory foam or latex layers atop a supportive pocket sprung or dense foam core. This blend can offer excellent pressure relief, contouring to your body while maintaining edge support and durability.
Temperature regulation is essential. If you tend to sleep hot, choose mattresses with breathable covers, gel-infused foams, or open-cell foams that promote airflow and help you stay cooler through the night.
Allergen considerations. Hypoallergenic fabrics and antimicrobial treatments can be important for sensitive sleepers. If you’re prone to allergies, check for certifications and cleaning guidance to keep your mattress fresh and comfortable.
What Are the Most Popular Types of Extra Thick Mattresses?
Memory foam with a thick comfort layer provides deep contouring and pressure relief, ideal for side sleepers seeking cuddle-like support. Hybrid mattresses combine coils with foam or latex for robust support and better bounce, while still offering the plushness of a thick top layer. Latex options deliver natural resilience and cooling properties, often with a longer lifespan. Pillow-top and euro-top variants add an extra soft, plush surface for those who prefer a cloud-like feel on top of strong underlying support.
How to Maintain an Extra Thick Mattress?
Rotate or flip as recommended by the manufacturer to promote even wear and extend the life of your thick mattress. Use a high-quality mattress protector to guard against spills, stains, and dust mites. Regularly vacuum the surface to remove dust and allergens, and air out the mattress after heavy use or in humid climates. If your model includes removable covers, launder them according to care instructions to maintain freshness and longevity.
Pair your extra thick mattress with a supportive bed base, slatted bases, solid platform frames, or adjustable bases can all work well, depending on your mattress design. Avoid overly soft foundations that could compromise the intended support of a thick comfort layer.
What Are the Key Benefits of an Extra Thick Mattress?
Enhanced pressure relief for hips and shoulders, especially for side sleepers, helps reduce tossing and turning. Improved durability and long-term shape retention mean fewer sagging concerns and better sleep quality over time. A thicker mattress can also support better spinal alignment when paired with a suitable pillow and centerline support, making it a good option for people dealing with back pain.
With strong edge support, you’ll enjoy a larger usable sleeping surface. The right thick mattress also often includes improved motion isolation, which is beneficial for couples who share a bed and don’t want to disturb their partner during movement.
How to Choose the Right Size for an Extra Thick Mattress?
Consider your room space and bed frame compatibility. Common sizes include single, double, queen, king, and super king. If you’re upgrading from a thinner mattress, measure against your current bed rails and ensure the thickness doesn’t impede headboard or footboard clearance. For couples, a larger size like queen or king offers more shoulder-to-hip space, improving comfort and reducing motion transfer.
Remember to check the weight of the mattress, especially for very thick models. Heavier mattresses may require assistance for setup, but they typically provide sturdier support and durability once in place.
Frequently Asked Questions
What counts as an “extra thick” mattress, and how thick should it be?
In retail terms, “extra thick” usually starts around 25cm (10 inches) and goes up to about 40cm (16 inches). The best thickness for you depends on your weight, sleeping position, and preference for plushness versus support. If you share your bed with a partner or you move a lot in your sleep, a thicker model can help distribute weight more evenly and reduce motion transfer on most nights.
Do extra thick mattresses help with back pain?
For many people, a properly supported spine reduces low back pain. An extra thick mattress with a zoned or high-density core can provide targeted support where you need it most while allowing a comfortable top layer for pressure relief. If you have chronic back pain, look for a model with firm support and a medium to medium-firm feel, plus good edge support and durable materials designed for long-term alignment.
Are extra thick mattresses harder to move, and do they require special bases?
Yes, thicker mattresses tend to be heavier, which can make setup a bit more challenging. They generally work well with solid platform bases, slatted bases with adequate support, or adjustable bases that match the mattress design. Always check manufacturer guidance for compatibility with bed frames and bases, especially for memory foam or latex models that rely on stable support to perform as intended.
What maintenance tips will keep an extra thick mattress performing well for years?
Rotate regularly to promote even wear and prevent sagging in one area. Use a breathable, waterproof mattress protector to guard against spills and moisture, and launder any removable covers according to care instructions. Air out the bed periodically, especially in humid environments, and keep the sleeping environment cool and well-ventilated to extend the life of cooling foams and latex layers.
With our range of Extra Thick Mattresses, you’ll find options featuring memory foam, cooling gel layers, pocket springs, latex, and hybrid constructions, all designed to offer lasting comfort and support.
