Discover comfort and space with our extensive selection of 5ft King Size Mattress options on Wowcher. From cooling memory foam to supportive hybrid cores, we bring premium sleep solutions at unbeatable prices.


Whether you're upgrading a master suite or furnishing a guest room, a 5ft king size mattress offers generous width and scale to suit couples or solo sleepers who want room to move. Our deals cover memory foam, latex, pocket sprung, and orthopaedic designs, all designed to deliver proper spinal alignment and restful nights.


Unbeatable Deals on Online 5ft King Size Mattresses


Shop 5ft king size mattresses in the UK with confidence. Look for memory foam with cooling gel, breathable covers, and reinforced edge support. Compare brands, check warranty, and seize Wowcher-exclusive discounts and bundles that include mattress protectors, toppers, and pillows. Our marketplace features top names in sleep technology, from hypoallergenic covers to firm pocket sprung cores, all available at reduced Wowcher prices.


Browse 150x200 cm or 152x200 cm options, commonly marketed as 5ft king size mattress in the UK, and find the right balance of support and softness. Whether you prefer a cooler hybrid with springs and memory foam or a plush layered euro top, you’ll often see clear specs on airflow, temperature regulation, and durability.


What to Consider When Choosing a 5ft King Size Mattress?


Start with your room and bed base. Ensure your 5ft king size mattress fits the frame and leaves space for nightstands. Consider the total height including any mattress topper or protector, as UK heights range from around 25 cm to 40 cm with toppers. Material choice matters too: memory foam with cooling technology or latex can offer different levels of bounce, contouring, and breathability for long, undisturbed sleep.


Think about support cores like pocket springs or traditional springs. For couples, edge-to-edge stability reduces roll-off and transfers less motion. If you suffer from back or joint pain, an orthopaedic or medium-firm to firm 5ft king size mattress can provide better spinal alignment. If you sleep hot, look for breathable knitted covers and gel-infused foams to improve temperature regulation.


Filling and feel matter: memory foam hugs contours, latex offers buoyant support, and hybrid combines springs with foam for a balance of comfort and support. Consider allergy-friendly fabrics and removable, washable covers for easy care.


What Are the Most Popular Types of 5ft King Size Mattresses?


Memory foam 5ft king size mattress options are favored for contouring pressure relief and motion isolation, making them ideal for couples and side sleepers. Gel-infused variants help keep the surface cooler during sleep.


Hybrid 5ft king size mattress designs combine individually wrapped springs with foam layers for a responsive feel and strong support, often with enhanced edge support and better bounce.


Pocket sprung mattresses offer targeted support where you need it most. They’re popular in the 5ft king size mattress category for their durability and customized feel, particularly when paired with a comfortable pillow top.


Latex mattresses provide natural resilience and bounce with breathable properties, suitable for people who want a quicker response and less heat buildup. For budget-conscious shoppers, high-quality foam or hybrid layers can deliver similar benefits at a lower price point.


How to Maintain a 5ft King Size Mattress?


Rotate a 5ft king size mattress every three to six months to promote even wear and extend its lifespan. Use a breathable mattress protector to guard against spills, stains, and dust mites, especially if you’re prone to allergies.


Regularly vacuum the surface to remove dust, and avoid using harsh cleaners that could degrade surface fabrics. If your mattress has a removable cover, wash it according to the label so you maintain hygiene without compromising the material.


Air the bed after heavy use and ensure the room has good ventilation. Do not fold or bend the mattress, and always use a compatible bed base or slatted frame to maintain structural integrity for your 5ft king size mattress.


How Do I Choose the Right Firmness for a 5ft King Size Mattress?


Your preferred firmness depends on sleeping position, body weight, and personal comfort. Side sleepers typically benefit from a softer to medium feel to relieve pressure on shoulders and hips, while back sleepers may prefer a medium-firm option for better spinal alignment. Stomach sleepers often need a firmer surface to prevent sagging at the hips.


If you share a bed, prioritize a design with strong motion isolation, memory foam or hybrid cores can reduce partner disturbance. For heavier individuals, a firmer core with reinforced edge support in a 5ft king size mattress helps prevent sink-in and maintains stability across the surface.


Always check the return policy and trial period. Many Wowcher listings offer generous trial durations so you can test comfort in real sleep scenarios before committing long-term to a 5ft king size mattress.


Do 5ft King Size Mattresses Come in UK Sizes and What Does 150x200 cm Mean?


Yes. In the UK, a standard 5ft king size mattress typically measures 150 cm wide by 200 cm long, commonly marketed as 150x200 cm. Some providers offer 152x200 cm as well, though the 150x200 cm dimension remains the most common. This size is designed to fit most standard king bed frames and gives couples ample sleeping space.


When shopping, verify the exact dimensions in the product description and consider any toppers or protectors you plan to use. If your bed frame has a limited footprint, measure the frame and ensure the mattress aligns with the edges for a neat appearance and stable foundation.


What Features Should I Look For in a 5ft King Size Mattress?


Edge-to-edge support helps prevent roll-off when sitting on the sides and makes it easier to sit on the edge of the bed without feeling as though you’ll slip off. Look for moisture-wicking, breathable covers and cooling foams if you tend to overheat at night. Hypoallergenic fabrics and antimicrobial treatments can help reduce allergy symptoms.


Consider motion isolation for couples, ease of cleaning with removable covers, and the availability of a warranty. A well-made 5ft king size mattress that suits your climate, sleep style, and budget will deliver long-term comfort and better sleep quality.


How Do I Get the Best Deals on a 5ft King Size Mattress on Wowcher?


Use Wowcher’s search filters to compare 5ft king size mattress options by material, firmness, and price. Look for bundles that include a mattress protector and pillow, and watch for free delivery or regional deals. Read product reviews, check the warranty, and take advantage of seasonal promos that reduce the cost of memory foam, hybrid, or orthopedic 5ft king size mattress models.


For best value, compare similar build types, memory foam versus hybrid, and consider purchasing a compatible base or bed frame to ensure proper support. Always verify return policies and trial periods on Wowcher listings so you can sleep with confidence on your new 5ft king size mattress.
