Frequently Asked Questions
What size is considered a king size mattress in the UK?
In the UK, a standard king size mattress measures approximately 150 cm by 200 cm (60 inches by 80 inches). A super king size mattress is larger at about 180 cm by 200 cm (72 inches by 80 inches). When shopping, check exact dimensions on listings to ensure your bed frame accommodates the mattress comfortably.
What are the best materials for a king size mattress in the UK?
Memory foam king size mattresses offer excellent pressure relief and motion isolation, ideal for couples. Hybrid king sizes combine springs with foam for a balanced feel. Pocket sprung options provide targeted support and durability, while latex models deliver buoyant support and cooling. Consider your preferred sleep position, temperature control, and any allergies when choosing materials.
How do I choose the right firmness for a king size mattress?
Side sleepers often prefer medium to medium-soft for pressure relief at the shoulders and hips, while back sleepers may opt for medium-firm for better spinal alignment. Stomach sleepers generally benefit from a firmer feel. If you share the bed, consider a mattress with good edge support and zoned coils or foam layers to minimize motion transfer and maximize usable surface area.
Do king size mattresses in the UK come with free delivery or discounts?
Many Wowcher UK listings offer free delivery on qualifying king size mattresses or discounted shipping with promotional codes. Always check the terms at checkout, including minimum spend, regional exclusions, and whether the deal includes setup, removal of old bedding, or packaging disposal. Free delivery can significantly reduce total cost, especially for large items.
What should I look for when comparing king size mattress deals?
Compare price per square metre, cover materials, and trial periods. Look for a generous sleep trial and a solid warranty. Check the return policy and ensure there is a clear path for exchanges if firmness or size isn’t right. Also consider the frame compatibility, ventilation, and whether a topper is included or available as an add-on.
How do I arrange delivery for a king size mattress?
Most Wowcher listings provide a delivery window and tracking once dispatched. For large items like king size mattresses, you may select standard delivery, express options, or next-day services where available. Some deals include white-glove delivery and setup. Be sure to confirm delivery accessibility for staircases, entrances, or elevator access at checkout.
Are there eco-friendly or hypoallergenic king size mattress options in the UK?
Yes. Look for hypoallergenic covers, natural latex or sustainably sourced materials, and certifications like Oeko-Tex or CertiPUR. Hypoallergenic king size mattresses reduce allergens and dust mites, which can benefit allergy sufferers. Check for washable covers and easy-care instructions to maintain a fresh sleeping environment.
What are common maintenance tips for king size mattresses?
Rotate or flip your mattress if the design allows it, at least every three months to promote even wear. Use a breathable mattress protector to guard against spills and stains. Vacuum the surface occasionally to reduce dust buildup. Follow manufacturer guidelines for cleaning and warranty care, and replace the mattress when support or comfort deteriorates beyond a reasonable threshold.
How can I find the best king size mattress deals in the UK on Wowcher?
Use filters for size (king or super king), material type, firmness, and price range. Watch for limited-time flash deals, seasonal promotions, and new-brand introductions. Add items to your cart to see final checkout prices with delivery included, compare multiple listings side by side, and read customer reviews to gauge real-world comfort and durability.
