A small double mattress and a double mattress differ primarily in size, which impacts their suitability for various spaces, sleeping preferences, and budgets. Below is a comparison of the two, along with their pros and cons.

Size Comparisons

Small Double Mattress:

  • Dimensions: 4ft wide x 6ft 3in long (120cm x 190cm) in the UK; in the US, often referred to as a "three-quarter" or "full" at around 48in x 75in (122cm x 190cm).
  • Surface Area: Approximately 75% of a standard double mattress.

Double Mattress:

  • Dimensions: 4ft 6in wide x 6ft 3in long (135cm x 190cm) in the UK; in the US, 54in x 75in (137cm x 190cm).
  • Surface Area: Standard size for two people, offering more width than a small double.

Feature Comparisons

Features of Small Double Mattresses

  • Width: 120 cm (4 feet)
  • Length: 190 cm (6 feet 3 inches)
  • Best for: Single sleeper, small room, guest room
  • Space efficiency: Helps to compact space
  • Comfort for two sleepers: Cramped for couples
  • Bedding cost: Usually slightly cheaper bedding
  • Availability: Common but usually fewer options than double

Features of Double Mattresses

  • Width: 135 cm (4 feet 6 inches)
  • Length: 190 cm (6 feet 3 inches)
  • Best for: Couples, slim couples, single sleeper who prefers more space
  • Space efficiency: Takes up more bedroom space
  • Comfort for two sleepers: More comfortable for two sleepers
  • Bedding cost: Standard, slightly more expensive
  • Availability: Plenty variety and widely available

Pros and Cons of Small Double Mattresses

Pros of a Small Double Mattress:

  • Space-Saving: Ideal for smaller bedrooms, apartments, or guest rooms where floor space is limited.
  • Cost-Effective: Generally cheaper than a double mattress due to its smaller size, and bedding (sheets, duvets) is slightly less expensive.
  • Good for Solo Sleepers: Offers ample space for one person, especially for teenagers, young adults, or single adults who want more room than a single bed.
  • Versatile: Fits well in multi-purpose rooms (e.g., home offices that double as guest rooms).

Cons of a Small Double Mattress:

  • Tight for Couples: Too narrow for two people to sleep comfortably, especially if either is a restless sleeper or prefers more space.
  • Limited Availability: Fewer mattress models and brands offer small double sizes compared to standard doubles, limiting choice.
  • Resale Value: Less demand in the second-hand market, as couples typically prefer larger mattresses.
  • Not Ideal for Taller People: The standard length (190cm) may feel short for those over 6ft tall.

Pros and Cons of Double Mattresses

Pros of a Double Mattress:

  • Better for Couples: The extra 15cm (6in) in width provides more room for two people, making it more comfortable for shared sleeping.
  • Widely Available: More brands, styles (memory foam, pocket sprung, hybrid), and firmness options are available in double size.
  • Standard Size: Bedding and bed frames for double mattresses are easier to find and come in a wider variety of designs.
  • Future-Proof: Suitable for growing households (e.g., couples or those planning to share the bed in the future).

Cons of a Double Mattress:

  • Larger Footprint: Takes up more floor space, which can be an issue in smaller bedrooms or apartments.
  • Higher Cost: Double mattresses and their bedding are slightly more expensive than small doubles due to the larger size.
  • Weight and Handling: Heavier and harder to move or rotate, especially for one person.
  • May Be Excessive for Solo Sleepers: Single sleepers in small spaces might find the extra width unnecessary.

Key Considerations

Do take room size, sleeping arrangement, budget, and future needs into considerations.

Room Size: Measure your bedroom to ensure the mattress fits comfortably with space for other furniture. A small double is better for rooms under 10ft x 10ft, while a double suits larger spaces.

Sleeping Arrangement: If you’re a solo sleeper who likes to spread out or a couple on a budget, a double mattress is more versatile. For a single sleeper in a compact space, a small double is sufficient.

Budget: Small doubles are typically 5-15% cheaper than doubles, depending on the brand and material (for example, memory foam vs. sprung).

Future Needs: A double mattress might be a better long-term investment if you anticipate sharing the bed or moving to a larger space.

Recommendation

When to buy small double and when to buy double mattress?

Choose a small double if you are a solo sleeper with a small bedroom or need a guest bed for occasional use.

Choose a double if you share the bed with a partner or want more space and flexibility for future needs.
