Why our sleep experts loved it

Today we’re taking a closer look at the Quilted Fusion 4000 Pocket Mattress from Harrison Spinks. A well established model from the popular manufacturer which fits in the upper quadrant in terms of costs and quality. Popular rivals to this brand would include the likes of Therapur, Tempur and Hypnos.

For those who don’t know, the Fusion mattress range is part of the Harrison Spinks collection, a hugely popular mattress manufacturer who has spent decades producing high quality bedding accessories. 

Diving deeper into the Quilted Fusion 4000 Pocket Mattress we will start by breaking down the mattress into its core components, namely, the layers and starting with the comfort layer. In this instance this mattress comes with a fairly breathable recyclable Enviropad filling which is both soft and soothing, while also proving to offer fantastic temperature regulation helping you stay at the right temperature throughout the entire year.

Moving onto the support layer and, as the name of the product suggests, you have an impressive assortment of pocket springs. When it comes to pocket springs you are already getting arguably the best body contouring layer available for mattresses which will typically perform better than it’s open coil traditional competition. 

Onto the mattress cover and you are getting a soft, quilted panel cover which again, compliments the cooling nature of the comfort layer and works hand in hand with the support layer to produce an all-in-one specialist mattress that has great temperature controls. What’s more, the cover features robust turning handles which will aid mattress rotation, helping to ensure sufficient and even settlement across the mattress layers preventing dipping and uneven wear.

This mattress is available in all popular sizes from small single all the way to super-king, with the euro size small double also featuring in the lineup. It’s common industry practice to price small-single and small-double at the same rate as single and double and it’s good to see that this is being reflected in this lineup.

The mattress will most likely suit those looking for a high quality product with very little in terms of compromise. Ideal for those who get too hot or cold at night, the temperature regulation properties of these mattresses will be much appreciated. 

Additionally, since the mattress is available in firm, this product will suit those who sleep on their stomach or back most typically, although those that are heavier or without hourglass figures may find side sleeping equally enjoyable.

With a 5 year guarantee, it’s clear that both Harrison Spinks and Mattress Online both have large ambitions for this mattress, effectively guaranteeing it for over half of the typical mattress lifecycle which should go a considerable way toward providing quality and confidence in the mattress.

*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.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • 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.


  • 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.
