Assessed from Mattress Online's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main appeal is honest 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 £35.00 if you need it. The 100-night trial gives you time to be sure. Yes, the 1-year guarantee is short, but at this price the risk is modest, and it's handcrafted in the UK by a National Bed Federation approved brand.
Key Features & what's inside
- 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.

Who's it NOT for?
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.
Mattress Online Classic Gold Ortho Mattress
Across 1,521 reviews on the Mattress Online product page, rated 4.5 overall, customers report improved back pain and comfortable sleep for back and side sleeping, with quality seen as good for the price. Some find it firmer than expected, and a few raise durability concerns.
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. Prices range from £144 to £314 depending on size.
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 costs £20.00, and old mattress removal is £35.00.
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.
