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.

Key benefits
- The classic couples' footprint: At 135 x 190cm, the UK double gives two people sharing 67.5cm each, enough for most couples while leaving space to move around the room.
- Firm support for two, kept affordable: Open coil springs spread weight evenly across the full width, which means both sleepers get the same supportive, slightly traditional feel from edge to edge.
- Fits typical UK bedrooms: We suggest at least 2.6m x 2.8m of floor space, which most British bedrooms clear comfortably, often with room for bedside tables on both sides.
- A practical guest room choice: The double sleeps visiting couples without dominating a spare room that also holds a wardrobe and drawers, and the modest price suits a bed used a few weekends a year.
- Cheap and easy to dress: Double sheets and 200 x 200cm duvets are stocked everywhere at every price, which helps when you're furnishing a whole home on a tight budget.
This size suits you if...
You're a couple after the traditional shared size in a room where a UK king would feel cramped, you're kitting out a first flat or a whole house and need a dependable bed for two without a big spend, or you're setting up a guest room that hosts visiting couples a handful of times a year.
Consider another size if...
You and your partner disturb each other easily, since open coils transfer more movement than pocket springs and 67.5cm each leaves little buffer. If your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead, which gives 75cm each.

FAQ's
Is the Classic Gold Ortho in a UK double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm of width each, the long standing standard for two sharing. One caveat with this particular mattress: open coil springs transfer more movement than pocket springs, so a restless partner is more noticeable in a double than in a wider size. Light sleepers may prefer the UK king's extra room.
What room size do I need for the Classic Gold Ortho double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. The mattress itself is 135 x 190cm, which leaves space in a typical UK bedroom for a wardrobe, a chest of drawers and bedside tables on both sides. If your room is smaller than that, the UK small double needs only 2.4m x 2.8m.
Should I get the Classic Gold Ortho in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king, and gives 7.5cm less width per sleeper. If your room allows at least 2.7m x 2.9m and you're easily disturbed, the UK king's 75cm each softens the open coil movement transfer. In a smaller room, or on a tight budget, the UK double is the sensible pick.
Does the Classic Gold Ortho double suit a guest room?
It's a natural fit. The medium firm, orthopaedic feel is a safe middle ground for guests whose preferences you can't predict, and the 135 x 190cm footprint sleeps visiting couples without swallowing a spare room. At the budget end of the market, it also avoids overspending on a bed that's used occasionally rather than nightly.
Where can I buy the Classic Gold Ortho mattress in a double?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. Availability can differ between sizes, so what's stocked in the UK double may differ from the UK single or UK king. Checking the live table gives you the current picture rather than a snapshot that dates quickly.
