Why should you choose this mattress?
The Iona is built around natural materials: latex, British wool, organic lambswool, silk, cotton, hemp and flax, with a seaweed-infused tick. It's Certified Organic by the Soil Association, which helps if you want to know what you're sleeping on. Two rows of hand-sewn side-stitching give edge-to-edge border support, so you can use more of the bed's width. It's hand tufted and handcrafted in Buckinghamshire, and the 10-year guarantee backs up the build. It suits anyone who puts natural construction and craftsmanship first, although you'll need to judge the feel yourself.

Best suited for?
Eco-conscious buyers
Certified Organic by the Soil Association and filled with latex, British wool, silk, cotton, hemp and flax, so you know the natural materials you are sleeping on.
Couples
Two rows of hand-sewn side-stitching give edge-to-edge border support, which means both partners can use more of the bed's width right up to the sides.
Allergy sufferers
Natural fillings such as latex, wool and cotton, plus Soil Association organic certification, suit those who want to know exactly what goes into the bed.
If you need to know the firmness before you buy, this might not be the best choice, because Hypnos doesn't publish a rating. It's also single sided with a no-turn design, so you can't flip it. If you want to avoid animal-derived materials, the wool, lambswool and silk fillings rule it out. It's a premium mattress too.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
