Why should you choose this mattress?
Choose the Serenade Ortho if you sleep better on a firmer surface and want to keep the cost down. The traditional open coil springs are joined in a lattice design, which means your weight is spread across the whole sleeping surface to ease pressure and help spinal alignment. Above them, soft white fibres take a little of the edge off the firmness, and the woven damask cover doesn't retain heat, a plus if you tend to sleep warm. It's a budget option, and the fillings are simpler than pricier hybrids, but for a spare room, a guest bed or a first mattress it does the essentials well.
Key features & layer details
Comfort Layer
Soft white synthetic fibres sit at the top, which means a cosy surface feel rather than a sink-in one. They're durable and resilient, so the layer should hold its shape over time.
Support System
Traditional open coil springs are interlaced in a lattice design, which means the whole surface works together to spread your weight evenly. That helps relieve built-up pressure and supports spinal alignment, though it does mean more motion transfer than pocket springs if you share the bed.
Cover
A finely woven damask cover finishes the mattress, soft to the touch and built to last. It doesn't retain heat, which hot sleepers will appreciate.

Best suited for?
Budget buyers
The copy calls it a budget option with simpler fillings, so it gives you firm support without the cost of pricier hybrids.
Guest rooms
Straightforward open coil support and a durable fibre layer do the essentials well, which makes it a sensible choice for a spare room or guest bed.
Warm sleepers
The finely woven damask cover doesn't retain heat, which means the surface should stay more comfortable if you tend to sleep hot.
Back sleepers
Interlaced open coil springs spread your weight across the whole surface, which means firm, even support that helps keep your spine aligned.
Heavier sleepers
The firm feel and lattice of connected coils work together to spread weight evenly, so the mattress should feel supportive rather than sinking away.
Lightweight side sleepers may find the firm feel puts too much pressure on hips and shoulders. Couples who are easily disturbed should note that open coil springs transfer more movement than pocket springs. And if you want deep, plush comfort layers, this simple fibre-topped build isn't it.
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
Is the Romantica Serenade Ortho mattress firm?
It's rated Firm. That said, across owner reviews some sleepers describe the feel as closer to medium-firm, so if you need a very hard surface it may feel slightly softer than expected.
Does the Romantica Serenade Ortho come with a trial?
Mattress Online offers a 100-night trial. This is the retailer's own offer rather than a manufacturer promise, so if you buy elsewhere the terms may differ.
What guarantee does the Romantica Serenade Ortho have?
Mattress Online lists a 1 year guarantee on this mattress. That's shorter than many brands offer, which is one of the trade-offs at an affordable starting price.
How deep is the Romantica Serenade Ortho mattress?
It's 25cm deep, so standard fitted sheets should fit without any trouble.
What sizes does the Romantica Serenade Ortho come in?
It's available in UK Single, Small Double, Double and King. There's no Super King option, so couples wanting the widest bed will need to look elsewhere.
