The brand describes the Classic Gold Ortho as medium to firm, which means a supportive, slightly traditional feel rather than the deep sink of memory foam. It's 26cm deep and sits at the budget end of the market, and it comes with a 100-night trial and a 1-year guarantee direct from Mattress Online. If you want straightforward, firmer support without spending a lot, this is the sort of no-frills option worth a look. It suits back sleepers well, although lightweight side sleepers may find it a little too firm.

Why should you choose this mattress?
The main appeal is good value. Open coil springs are interlaced in a lattice design, which means your weight is spread evenly across the mattress to ease pressure and help keep your spine aligned. Soft white fibres above the springs add a cosy layer, and the knitted cover is breathable, useful if you tend to sleep warm. Delivery is generous: free next day on weekdays, free weekend delivery, a two-hour time slot, and old mattress removal for an extra charge if you need it. The 100-night trial gives you time to be sure. Yes, the 1-year guarantee is short, but at an affordable starting price the risk is modest, and it's handcrafted in the UK by a National Bed Federation approved brand.
Key features & layer details
Comfort Layer
Soft white synthetic fibres sit at the top, which means a cosy initial feel rather than a firm, flat surface. They're durable and resilient, designed to hold their shape over time.
Support System
Traditional open coil springs are interlaced and joined in a lattice design, which means your weight is distributed evenly across the bed. That helps relieve built-up pressure and supports spinal alignment, the core job of an orthopaedic mattress.
Cover
A knitted cover gives a soft, warm finish. It also enhances airflow and is breathable, which helps if you run a little hot at night.

Best suited for?
Back sleepers
The medium to firm feel and interlaced open coil springs spread your weight evenly, which means steady support that keeps your spine aligned while you lie flat.
Budget buyers
Sitting at the budget end of the market with a 100-night trial, it gives you firm, no-frills support without a big outlay.
Warm sleepers
The knitted cover is breathable and helps airflow, which means less trapped heat if you tend to run hot at night.
Guest rooms
A straightforward, supportive feel at an affordable level suits a spare bed, and the 100-night trial gives plenty of time to be sure.
If you like a soft, cradling feel or you're a lightweight side sleeper, the medium to firm tension may feel too solid. Couples who are easily disturbed should know open coils transfer more movement than pocket springs. And if a long guarantee matters to you, the 1-year cover here is brief.
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
How firm is the Classic Gold Ortho mattress?
Mattress Online describes it as medium to firm. In practice that means a supportive surface with a little softness from the fibre comfort layer on top, rather than a plush sink-in feel. Some owners report it feels firmer than they expected, so bear that in mind if you prefer a gentler surface.
Does the Classic Gold Ortho come with a trial period?
Yes. Buying direct from Mattress Online, you get a 100-night trial, so you can sleep on it at home and return it if it doesn't suit you. The guarantee is 1 year.
What sizes does the Classic Gold Ortho come in?
Eight sizes: UK Small Single, Single, Small Double, Double, King and Super King, plus EU Double and EU King.
How is the Classic Gold Ortho delivered?
Delivery to your front door is free, with next day delivery on weekdays, free weekend delivery, and free weekday delivery bookable up to 60 days ahead. You get a two-hour time slot. Room delivery and old mattress removal are available for an extra charge.
Is the Classic Gold Ortho good for back pain?
It's an orthopaedic design, and the open coil support system distributes weight evenly to relieve pressure and aid spinal alignment. Owner reviews on the Mattress Online site frequently mention improved back pain. That said, no mattress suits every back, which is where the 100-night trial helps.
