Why should you choose this mattress?
The Halifax is an extra-firm, non-spring foam mattress, so it suits people who want a flat, unyielding surface, such as back and front sleepers. The advanced reflex foam core is designed to spread your weight evenly, which reduces pressure points. It is double sided, with turning handles on the border, so you can flip and rotate it to even out wear. The stretch knit cover has a quilted finish. The downside is that extra firm won't feel right for most side sleepers or anyone who likes to sink in. At 18cm deep, it is a fairly slim mattress.
Key features & layer details
White fibre fillings
A layer of white fibre fillings sits in the quilted cover, above the foam interior. It adds a little surface cushioning on what is otherwise an extra-firm mattress.
Advanced reflex foam core
The core is advanced reflex foam, designed to conform to your body's contours and spread your weight evenly. For you, that means fewer pressure points, while the overall feel stays extra firm.

Best suited for?
Couples
Super king is among the six UK sizes, which gives two people a wider shared surface than a standard double would.

With six UK sizes on offer, from small single to super king, it is easy to match the mattress to whatever bed a spare room already has.
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.

FAQ's
What sizes does the Highgrove Halifax mattress come in?
It's available in six UK sizes: small single, single, small double, double, king and super king. That covers most standard UK bed frames, although you should always measure your frame before ordering, as boxed mattresses can't be returned as easily once opened.
How much does the Highgrove Halifax mattress cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It sits towards the more affordable end of the market, although we'd suggest checking what's included, such as delivery and any trial or guarantee terms, with the retailer directly.
Is the Highgrove Halifax a mattress in a box?
Yes. It's delivered rolled and vacuum-packed in a box, which makes it far easier to get into flats and rooms with tight access. Once unboxed, it expands to full size. Allow it time to fully settle before judging the feel.
