Despite it being a necessary choice among many, there are still a vast majority of whom will find the best orthopaedic mattress to be too firm for their liking. As such, the Catalonia from Sealy is considered a specialist mattress and has limited audience appeal for the average person.

Provided you do require an extra firm mattress, perhaps for orthopaedic reasons, or simply enjoy the board-like comfort that comes from extra firm tension products, this might be the one for you. Let's dive into some of the specifics.

Starting with the base layer, the Catalonia comes with an extra firm Posturetech Core Support spring unit which is made up of a patented coil spring design that is tightly wound to increase firmness beyond that of a typical base layer. The result is a good quality base that has zonal support that moves and adapts with each movement you make.

Onto the comfort layer, this sits at the top and features a deep layer of breathable tencel fibres that keep you warm while providing enough softness to derive a feeling of comfort and luxury. Some reviewers might find the comfort unsuitable and limited, however, their complaints would likely be miss-directed and the real issue would come back to one of suitability surrounding the firmer tension underneath. As before, extra firm mattresses are somewhat specialist and should be carefully considered.

Reasons to Buy

Not many extra firm mattresses around, if you require this degree of firmness then you can't go wrong with a Sealy branded product like the Catalonia.

Allergenic support through the ProShield technology will help mitigate issues.

5-year guarantee shows that the manufacturer and supplier both stand behind their product.

Reasons to Avoid

Unsuitable for most people.

Fairly long lead times will disappoint those looking for a mattress fast.

No euro sizing available.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the wizard above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

  • Overall Brand Rating
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.
