How to Choose a TheraPur ActiGel Mattress?

In order to choose the best Therapur mattress, you should look at the following features:

  • How deep the ActiGel layer is: either 2cm or 4cm. This Gel layer is responsible for keeping you cool at night.
  • You should also consider the number of pocket springs you want inside. Pocket springs provide very good body support and isolate motion transfer between sleeping partners. The TheraPur ActiGel Hazen and Simcoe models have open coil spring system (they come with 1 year guarantee). 
  • Some mattresses also come with a pillow top, so if you’re used to sleeping on a mattress with a pillow top, you have several options to choose from.
  • Finally, you’ll want to take a look at how deep the mattress is. The TheraPur ActiGel 800 Mattress is 22cm deep, while the highest model Therapur ActiGel Glacier 4600 Mattress is 30cm deep.

Alternatively, you can check out Bensons for Beds iGel mattress collection, which also has a layer of gel inside and has a similar price tag.

  • Many have said that their back pain has been alleviated or completely gone, and that they are waking up feeling refreshed and energised in the mornings.
  • The pocket springs stop movement from their sleeping partner, when they have restless nights.
  • A few customers found the mattress to be rather uncomfortably hard, but after sleeping on it for two weeks, giving it enough time for the mattress layers to settle in and has become very comfortable.


  • There have been several low reviews posted about the Therapur Actigel Glacier 3600 mattress, that it has sagged, or collapsed in the middle after a few weeks of usage. This is a problem that should be addressed with Dream’s customer service right away.

Some were able to adapt to the comfort, but there were others that didn’t see an improvement and were able to exchange it for a different one, with Dream’s 100 night comfort guarantee policy.
  • Only a handful of customers said that they sleep hot and that they find the mattress to be very warm.
