Mattress Online Classic Gold Mattress
The Classic Gold is Mattress Online's own budget mattress, built around traditional open coil springs, which means an even, familiar level of support rather than the contouring feel of pockets or foam.
- Even support helps spinal alignment
- Cosy fibre top without the sink
- 100-night trial

The brand describes the Classic Gold as medium, so it should suit back and stomach sleepers who like a bit of bounce. At 24cm deep with a soft fibre comfort layer and a damask cover, it's a simple construction. It's handcrafted in the UK, and you get a 100-night trial to change your mind, although the 1-year guarantee is short. For a spare room or a tight budget, it does the basics well.

Assessed from Mattress Online's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Why should you choose this mattress?
Price is the main draw here, and it comes in 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 and old mattress removal cost extra. 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 an affordable starting price.
Key features & layer details
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.

Best suited for?
Back sleepers
The medium-firm feel and interlaced open coil lattice spread your weight evenly, which suits lying on your back with a bit of bounce.
Front sleepers
A medium-firm feel with a soft fibre comfort layer on a coil base keeps your hips from sinking too far, which suits stomach sleeping.
Budget buyers
The copy calls it an affordable starting price and respectable value, so it does the basics well without a big outlay.
Guest rooms
A simple two-layer build with a 100-night trial makes it a sensible spare bed that does the basics well for occasional visitors.
European bed frames
Seven sizes include EU double and EU king, which many budget ranges skip, so it fits continental frames without hunting for a special order.
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.
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 mattress online classic gold?

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. It's 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 and old mattress removal cost extra.
