Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a mattress for buyers who want straightforward orthopaedic-style support without spending much. The open coil unit uses interlaced high-tensile steel coils joined in a lattice, which means support is spread across the whole surface rather than responding point by point. Above that, a layer of Advanced Comfort Foam gently contours to your body, so the firmer springs don't feel harsh against pressure points. It's hypoallergenic, vegan friendly and fire resistant to the BS7177: 2008 standard. The 1 year guarantee is short, but at £179 to £239 the risk is modest, and next day delivery means you're not waiting weeks to find out if it suits you.
Key Features & what's inside
- Quilted Cover. The cover and fillings are stitched together to create a patterned comfort quilt layer. This gives the sleep surface a soft, slightly cushioned first impression before you reach the firmer support beneath.
- Advanced Comfort Foam. A breathable foam that gently contours to your body shape, which means personalised comfort and tension relief at the shoulders and hips. It acts as the buffer between you and the spring unit below.
- Open Coil Springs. Interlaced coils of high-tensile steel joined together in a lattice provide the core body support. Because the coils are connected, the whole surface works as one, giving that traditional, evenly firm feel.

Who's it NOT for?
Couples who are easily disturbed may struggle, as an interlaced open coil unit transfers movement more than pocket springs do. Lightweight side sleepers could find the Medium Firm feel a little too solid at the shoulder. And if a long guarantee matters to you, the 1 year cover here is brief.

How firm is the Zante Ortho mattress?
MattressNextDay lists it as Medium Firm, and some owner reviews mention it feels firmer than anticipated. That leans it towards back and front sleepers or anyone wanting solid spinal support, rather than lightweight side sleepers who need more give.
What is the Zante Ortho mattress made of?
It has three layers: a quilted cover stitched together with the fillings, a layer of breathable Advanced Comfort Foam that contours to your body, and an open coil unit of high-tensile steel springs joined in a lattice. The whole mattress is 24cm deep and made in the UK.
Does the Zante Ortho mattress come with a guarantee?
Yes, MattressNextDay provides a 1 year guarantee. That's shorter than many brands offer, although the low price, from £179.00, softens the sting somewhat.
How quickly is the Zante Ortho delivered?
MattressNextDay offers free next day delivery to almost everywhere across mainland UK, though some addresses may incur a small fee.
What sizes does the Zante Ortho come in?
It's available in UK Single, Small Double, Double and King, priced from £179 to £239 depending on size.
