5ft King-Size Mattress

5ft King-Size Mattresses in Ireland - Over 400 Options with Free Delivery

The 5ft king-size mattress (150 x 200cm) gives couples an extra 15cm of width compared to a standard double, and that makes more difference than you might think. At Beds.ie, we stock over 400 king-size mattresses with free delivery across Ireland and Northern Ireland — a premium selection of pocket sprung, memory foam, hybrid, orthopaedic, and natural-fill mattresses for the best sleep your bedroom can offer.

King-size has become the go-to upgrade for Irish couples who find a 4ft6 double too snug. That extra width means less disturbance from a restless partner, more room to find a comfortable position, and a noticeably more spacious feel in bed. If your bedroom can accommodate it — a king-size bed needs a room at least 3.5 metres wide for comfortable access on both sides — it is worth the step up.

Construction Types

Pocket sprung king-size mattresses are our most popular choice, with individual springs that respond independently to each sleeper is weight and movement. Higher spring counts — 1,000, 1,500, 2,000 and above — provide finer support and better motion isolation. Memory foam king-size mattresses contour to your body shape and are excellent for pressure relief, particularly for side sleepers. Hybrid mattresses combine a pocket spring core with foam comfort layers, aiming to deliver the support of springs with the cushioning of foam.

Natural and Premium Options

For those who want the best, our premium king-size mattresses feature natural fillings like British wool, silk, cashmere, and cotton. These materials regulate temperature naturally — cooler in summer, warmer in winter — and provide a sleeping experience that synthetic fills cannot quite match. Hand-tufted models with natural fillings are the pinnacle of our range.

King-Size Dimensions

A standard Irish king-size mattress measures 150cm wide by 200cm long. This is 10cm longer than a standard double (190cm), which benefits taller sleepers. Make sure your bed frame or divan base matches — a 5ft king frame is required.
