About the TheraPur ActiGel® Glacier 1800 Combination Mattress
Last checked
The TheraPur ActiGel® Glacier 1800 Combination Mattress is a pocket-sprung build with gel foam quilted into the top, PurFibre® padding and a knitted ActiCool® cover, set up as firm, 5 of 5. An 1800-pocket spring count is a meaningful step above basic 1000-spring firm mattresses, especially for sleepers who want separate springs reacting under the shoulders, hips and lower back rather than one open-coil unit moving as a slab. The comfort stack is still fairly conventional. ActiGel® and fibre give a cushioned, responsive surface, but this is not the deeper pressure-relief recipe found in softer memory-foam hybrids or latex-topped pocket-sprung mattresses. The cushion top adds a plusher first feel, which matters because the underlying tension is uncompromising; several happier accounts describe it as firm with enough surface padding rather than flatly hard. Cooling is the most heavily signposted feature, and the spec does support some of that claim: gel quilting plus a cool-touch knitted cover should feel fresher on first contact than a plain polyester damask cover. In practical bedroom use, though, a protector and fitted sheet reduce direct contact with the cover, so the cooling story is more about a cooler upper layer and breathability than air-conditioning the bed.
The firm pocket-sprung platform makes most sense for back sleepers, some front sleepers and people who feel better held level through the pelvis rather than dipped into a softer comfort layer. Positive accounts repeatedly link the mattress with reduced back ache, a supportive feel and less night-time overheating, including from sleepers dealing with temperature swings, so the gel-and-cover specification is not just decorative for those buyers. Partner disturbance also comes up well in one detailed account, which fits the pocket-spring construction: individual springs tend to transfer less movement than traditional open-coil mattresses, although no edge-support system is named in the spec. Side sleepers are the awkward fit here. The same firm tension that keeps a back sleeper’s spine flatter can leave hips, ribs and shoulders short of sinkage, and low-scoring feedback repeatedly describes the mattress as harder than expected, with discomfort around the hip and rib area. Cooling feedback is also split: satisfied buyers describe a noticeably cooler sleep, while unhappy accounts say the effect disappears under normal bedding or even feels warmer, so the manufacturer’s cooling promise should be treated as conditional rather than universal. One severe low-score account also mentions early body dips and a ridge, which is not a broad theme in the sample but is a durability warning to rotate as advised. If the sleeper wants a firm, supportive mattress with a cooler first feel for back sleeping, this works. If the sleeper is mainly on their side or needs deep shoulder and hip cushioning, a medium-tension memory-foam hybrid or softer pocket-sprung tier makes more sense.

Nice and firm without feeling like a plank, and its helped my back feel better in the mornings. It does stay a bit cooler than our old mattress, though its not a miracle if youve got a thick protector on. Took me a few nights to get used to the firmness but Im sleeping more soundly now. Overall it feels well made and decent value.
Quite supportive and exactly what I needed for a good night's sleep. The cooling technology is a bonus.
Jamiel in the Potters Bar branch made the experience in store for us so easy from start to finish. He made it clear to us which mattress was best for our needs. He was very attentive throughout and gave us many options and prices to consider. We were impressed so much that we even stretched our budget to get something more suitable for our needs and were glad we did! The delivery was seamless, Ive never seen men move so fast up and down with a mattress over two flights of stairs. We definitely picked the best mattress. Our sleep has improved my back pain is much less, could not be happier. Thank you Dreams!
I recently took my 79yr Dad to Cheltenham Dreams to buy his first brand new bed. He did know he wanted a very firm mattress but apart from that he didnt have a idea of what was a good bed to buy. Thank goodness for Aaron. He was fantastic & took a long time showing my Dad all the different beds & firm mattresses. He showed Dad all the beds, which included Dreams beds, or other more expensive ones. Aaron put us under no pressure whatsoever to buy from Dreams or to purchase the more expensive bed. He described the differences in the beds very well & clear. Aaron made the whole experience seemless & due to Aaron's professionalism & outstanding advice Dad chose Dreams to purchase his new bed from. He's extremely happy with his purchase & was very impressed how quickly the two delivery drivers got his bed put together & ready to use. We'd definitely recommend to friends.
This mattress is amazing! I suffer from restless leg and since having this ive not had it once! Its so comfy and i get such a goof nights sleep.
Very comfortable, quality mattress, love the cooling gel top
Starts firm gets soft, I sleep grate on it
Really good quality mattress, the cooling geltop is really nice to sleep on. I suffer with back problems due to work but sleeping on this I never wake up sore.
Amazing sleep since we bought this mattress, struggling to get up to go to work:-)
I have to say, Im not sure if the cool touch thing works but nevertheless, this is the softest and most comfy mattress Ive ever had. I feel like I wake up enveloped in a hug every morning. Its very hard to leave bed in the morning. Service from Dreams has been amazing. Delivery guys were expert and turned up earlier than delivery slot.
This mattress is just perfect, I used to sleep on my side all the time but its be a waste not to sleep on your back with this. It properly supports your body while not compromising on comfort, truely like having a hotel bed in your own home.
Fantastic Mattress and even better customer service. We have had all our mattresses from dreams. This is my second Therapur mattress. The first one I had was for a double bed which I still have but have had for over 10 years, we upgraded to a king size. Very comfortable, Brilliant back support. Overall extremely happy from start to finish. Delivered with excellent care too. X
Very comfortable, a little on the high side but l like it.
Such a comfy mattress. Love the gel layer which stops me overheating. Make sure you follow the guidance for rotating the mattress to maintain its shape. Really comfy...not lots of movement which is great...stops me disturbing other half when I get up in the night!
Very comfortable. Light enough to turn with just 1 person(just). Very thick mattress and nice and cooling
Extremely comfortable, keeps me cool and supports me where I need to be supported. No more waking up when I turn over and wake refreshed feeling like I have slept. No more getting up aching and feeling 140 years old!
Wow, wow, wow. What a wonderful purchase, super sales staff - not pushy, helpful and informative. The delivery staff, polite, helpful and a phone call to ask if it is ok to be early. Since using the bed, my husband and I have had peaceful sleeps with no back or hip aches in the morning. Thank you the Dreams Team.
Wow! It's no understatement to say this has improved my quality of life! As someone who suffers with chronic back pain, and many perimenopause symptoms, this purchase is a game changer. This mattress isn't just comfortable and supportive, but really helps to regulate my body temperature, meaning I'm getting a decent night's sleep for the first time in years! I bought online, but only after excellent advice in my local store on what product would suit us best.
Wow what a comfortable mattress and the cooling aspect really works
Would recommend this mattress to anyone who loves a good night's sleep.
