While most people appreciated how firm the mattress was, a few people found it to be too hard and uncomfortable, although this should have been expected given the name of the product.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz 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.

Performance

  • 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.

Ease of Use

  • Turning handles
    ★★★★★
    ★★★★★
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.

Odour

  • 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.

My mum developed a bone condition which made her soft mattress uncomfortable and shed wake up in pain. We changed it for this rock hard mattress which, even though it is hard, its really comfortable and does the job she wanted it to. Its a thick mattress so fitted sheets only go half way down it but thats not a problem. Its an excellent mattress if youre looking for a super firm one.

I had been sleeping on the floor for 2 years before buying this mattress, and was sceptical as to whether the mattress would be hard enough for me. After 3 or 4 years of suffering with lower back pain, I am delighted that after just a few nights sleeping on this mattress, I am virtually now pain free!! Very, very happy with it, would definitely recommend if you need a hard mattress.

Easy to order and the fact it was made in the uk was well advertised. The quality is good and it does exactly what is says on the box. It is an extremely firm mattress, so be very certain that you want a firm mattress before buying.

As named, hard rock firmness provides great support and has done a really good job on my back pain. It is firmer than the general "extra frim" ones and it's exactly what I've been looking for.

Ultra firm as advertised. When the memory foam moulds you get a great nights sleep and feel fresh in the morning if this type of mattress is what youre used to or looking for.
