Assessed from Mattress Online's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Price is the main draw here: £159 to £319 across seven sizes, from small single up to king, including EU double and EU king, which many budget ranges skip. The 100-night trial gives you a proper chance to test it at home, and delivery is genuinely flexible: free to most locations, next day on weekdays, or a chosen weekday up to 60 days ahead, with a two-hour slot. Room delivery costs £20 and old mattress removal £35. Across 492 reviews on the Mattress Online product page it holds a 4.4 rating, respectable for the price. The 1-year guarantee is the trade-off, and it's a fair one at this cost.
Key Features & what's inside
- Comfort Layer. Soft white synthetic fibres sit on top, which means a cosy initial feel without the sink of memory foam. They're designed to be durable and resilient, holding their shape over time.
- Support System. Traditional open coil springs are interlaced in a lattice design, joined together so the whole surface moves as one. That spreads your weight evenly, easing built-up pressure and helping spinal alignment, though you'll feel more partner movement than with pocket springs.

Who's it NOT for?
If you share a bed and are sensitive to movement, open coils transfer motion across the whole surface, so a restless partner will be noticeable. Heavier sleepers or anyone with back issues wanting firm, targeted support may find it a little basic. It's also not the pick for a main bed you expect to keep for a decade.
Mattress Online Classic Gold Mattress
Across owner reviews summarised on the Mattress Online product page, buyers generally find it comfortable with good material quality for the price, though some report insufficient support and noisy springs. It's most often seen as a sensible choice for budget-conscious buyers and occasional use.

How firm is the mattress online classic gold?
Mattress Online describes it as medium. With open coil springs and a soft fibre top layer, expect a supportive, slightly bouncy feel rather than a sinking one. It suits most back and stomach sleepers, although lightweight side sleepers may want something softer at the shoulder.
Does the classic gold mattress come with a trial?
Yes, Mattress Online offers a 100-night trial, so you can sleep on it at home and return it if it doesn't suit. The guarantee is 1 year, which is on the short side, but reasonable given the price.
What is the classic gold mattress made of?
It's a traditional build: soft white synthetic fibres on top for comfort, an open coil spring unit for support, and a damask cover. It's 24cm deep, handcrafted in the UK, and conforms to BS7177: 2008 fire resistance standards.
What sizes does the classic gold come in?
Seven sizes: UK small single, single, small double, double and king, plus EU double and EU king. Prices run from £159 to £319 depending on size, which makes it one of the more affordable options if you need a European size.
How much does delivery cost for the classic gold mattress?
Delivery is free to most locations, with next day weekday delivery, a chosen weekday up to 60 days ahead, or weekend options, all with a two-hour time slot. Delivery is to your front door; delivery to a room of choice costs £20, and old mattress removal is £35.
