Super King Mattress — 180 × 200cm, the largest standard bed size.

A super king is 180cm wide by 200cm long (6ft) — the largest of the standard UK bed sizes. It is 30cm wider than a standard king (150 × 200cm) and one step below a bespoke emperor (200 × 200cm).

Width. A king is 150 × 200cm; a super king is 180 × 200cm — 30cm wider, the same length. Both use the identical natural latex layers and the same three feels; the super king simply gives each sleeper about 15cm more room, roughly the width of a small single each. See the king.

A super king (180 × 200cm) is the biggest standard size and fits a standard 6ft super king frame. An emperor is 200 × 200cm — 20cm wider again, and effectively bespoke: it needs an emperor frame and a large room. If your room and frame are standard, choose the super king.

Plan for at least 3.1m × 2.8m. A 180 × 200 frame is about 185 × 215cm with the surround, and you want roughly 60cm of walking space each side and at the foot. In a room under about 3m wide a king is usually the better fit.

The Spinery natural latex super king is €2,365 in the 20cm Original depth and €2,795 in the 25cm Elite depth. The feel you choose — Medium, Medium-Firm or Firm — doesn't change the price, and delivery anywhere in Ireland is free.

Here. We stock the 180 × 200cm super king in both depths — €2,365 in the 20cm Original and €2,795 in the 25cm Elite — with free delivery anywhere in Ireland, a 100-night home trial and a 10-year warranty. You can also lie on it at the Dún Laoghaire showroom before you buy.

Lower-back discomfort that's worse in the morning is often linked to a mattress that lets the lumbar curve drop out of neutral overnight. The Spinery's corrective layer is designed to support the lumbar arch while the comfort layer cushions hips and shoulders. Many customers tell us they notice the difference within the first few weeks — and the 100-night trial gives your body plenty of time to adjust. As always, talk to your physio or GP about persistent back pain.

The Spinery is a mattress, not a medical device — we can't make claims about treating sciatica or disc problems. What we can say is that the design supports proper spinal alignment, which is what your physio or chiropractor works to restore during treatment. If you're in active care, talk to them before changing your sleep setup.

Sleep on it for up to 100 nights at home. We ask for at least 30 nights first — your body needs a couple of weeks to adjust to proper support. If it's not right after that, get in touch and we'll guide you through the return.

Free delivery anywhere in Ireland — and not the "box at your door" kind. Our team brings the mattress to your bedroom, sets it up on your frame, and takes the packaging away. Delivery times vary by location; we'll confirm yours at checkout.

Original (20cm) is the classic — balanced support that suits most sleepers in any position. Elite (25cm) adds deeper contouring for side sleepers, anyone over ~90kg, or anyone with hip and shoulder sensitivity. Both use the same natural latex and Tencel® cover. Still unsure? Visit the showroom and feel both, or ring us on (01) 284 4093.

Boxed mattresses are typically petroleum-based polyurethane foam, vacuum-compressed to optimise shipping cost — not sleep. The Spinery is 100% natural latex that's never compressed, designed by three named clinicians, delivered to your bedroom and assembled for you, and built to last 10+ years instead of 5–7. It costs more upfront. It also doesn't need replacing twice as often.

Manufacturing defects and structural issues — visible sagging beyond normal wear, splitting or cracking of the latex core, and cover or seam defects. Natural latex doesn't develop the permanent body impressions memory foam does, which is why we can stand behind it for a decade.
