Introducing TheraPur ActiGel® Hazen Mattress, the latest in a growing line of mid-high quality mattresses from the internal brand Therapur. Unique to Dreams this mattress has a lot to offer at a keen price point. Interested to learn more? Let's dive in.

Let's start with the support layer, this sits at the base of the mattress and is what typically makes contact with the base of your bed and houses all the support your back and neck need. In this instance, a firm tension bonnell spring that has been used previously for orthopaedic support thanks to its fair body contouring properties and reasonable price point. This spring support base is more mid-range than premium, however, it is great for the price point and should last a number of years without any discomfort.

Onto the comfort layer and this is where Therapur really shines with its unique ActiGel comfort layer of luxurious quantities which offers many of the comfort properties of memory foam with non of the downsides. Predictably with gel, this layer proves far more breathable than other comfort options in other products and does a great job of offering comfort while keeping you cool. Ultimately we find the ActiGel layers to be ideally suited to those looking for an all-season mattress that will suit all temperatures.

Reviews are still coming in for this product as it is particularly new however, we have experience with the Therapur range at this point and have no doubt this will become a quick fan-favourite thanks to its great price point paired with reliable and comfortable ActiGel.

Reasons to Buy

ActiGel is one of my favourite comfort layers, it works really well.

A brand you can trust from the most popular mattress retailer in the UK.

Price point is more than reasonable.

Numerous sizes available.

Reasons to Avoid

Long lead time is disappointing and somewhat the norm for many mattresses from this retailer. They make up for it in great customer service and quality but you do have to plan ahead a fair bit.

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 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.
  • 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.

What Makes The TheraPur ActiGel® Hazen Mattress Great?

Firm comfort grade

Firm tension mattresses are most often suited to those who need a bit more support, typically for their back and neck. Mileage will vary depending on your weight and BMI as the tension and how it feels will ultimately be impacted as such. We also see firm mattresses been commonly recommended for their orthopaedic support. Ideal for back and stomach sleepers, although heavier people may find it suitable..

2cm of ActiGel® foam for improved support, airflow & temperature regulation

PurFibre® layers for enhanced comfort & support


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems

Online only

This mattress is not sold in stores and is instead an online-only model. That works quite well for us, since our core line-up or reviews and specification highlights are all based around online models.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Comes with our 40-Night Sleep Guarantee

The 40 night sleep guarantee is great as it allows you to exchange the product if you are not completely satisfied. This was one of the final challenges for online retailers to overcome comparable to traditional bricks and mortar where you can trial the product in store. Buy with confidence on this model.

Rest easy with a 1-year guarantee

A one year guarantee is suitable for many as the vast majority of problems that may occur often do so within that first year. At the same time, more and more retailers are beginning to offer multi-year warranty and guarantees although these often come at a slightly higher price point on average.
