FAQs on 5ft King Size Mattress

What should I look for when buying a 5ft King Size mattress?

Consider firmness level (soft, medium, firm), material type (memory foam, pocket spring, hybrid), and your sleep position. Check thread count on covers, weight capacity, and whether you need hypoallergenic properties. Read reviews from other side sleepers or back sleepers to match your needs.

No. A 5ft King measures 150cm wide by 200cm long, while a standard UK King is 150cm by 200cm—theyre identical. However, a Super King is larger at 180cm wide. Always confirm dimensions before ordering, as 5ft refers to the traditional UK King specification.

Measure the internal width and length of your bed frame in centimetres. A 5ft King requires minimum 150cm width and 200cm length. Check the depth too—if your frame is under 25cm deep, opt for a thinner mattress. Verify your bed base can support the weight.

Memory foam moulds to your body, offers pressure relief, and minimises partner disturbance. Pocket springs provide firmer support, better airflow, and suit heavier sleepers. Hybrids combine both. Memory foam suits side sleepers; springs suit back sleepers and those who run hot.

Next day delivery is available on selected in-stock 5ft King mattresses—check for the delivery badge on product listings. Standard delivery takes 3–7 working days and is free. Express options are subject to postcode and item availability. Confirm details at checkout.

A 5ft King (150cm x 200cm) is suitable for most bedrooms but requires at least 2.5 metres length and 2.8 metres width for comfortable access. Measure your space first. In very compact rooms under 3m x 3m, consider a Double or Queen instead for better circulation.

Rotate your mattress 180 degrees every 3 months to ensure even wear. Most modern mattresses shouldnt be flipped—check your product label. If flippable, alternate flipping and rotating every 6 months. This extends lifespan and prevents sagging and body impressions.

Vacuum monthly using an upholstery attachment. For stains, use a damp cloth with mild soap and allow to air dry completely. Protect with a mattress protector to prevent spills and dust mites. Air in sunshine quarterly. Avoid harsh chemicals and excessive moisture.

Yes, if you share a bed or value space. A 5ft King offers 15cm more width than a Double, reducing partner disturbance and improving comfort. Quality 5ft King mattresses last 7–10 years. Invest in medium firmness and pocket springs for best durability and value.

Most 5ft King mattresses include a manufacturers warranty covering defects—typically 3–10 years depending on brand and quality. Read terms carefully: warranties usually exclude normal wear, sagging under 2.5cm, and staining. Our customer service team can clarify specific warranty details per product.
