What Makes It Great

Comfortable mattress. Wanted as close to our previous. The mattress isn’t too deep so makes getting in and out of bed good compared to very deep mattresses. Only negative is that it doesn’t seam to have the support of the edges compared to our old dreams mattress which means we have had to catch ourselves from falling out of bed on a few occasions. If you roll over in the night and get too close to the edge the whole mattress gives way underneath you.

Your mattress should be rotated on a regular basis as this is the easiest way to prolong and increase the longevity of your mattress. The main benefits to regularly rotating your mattress is the continued support and comfort while reducing any risk of sagging that may otherwise occur

A Medium firmness mattress is the most common build offered due to the range of suitability offered in such a mattress. This type of mattress will be better suited toward averagely weighted people, while lighter people should opt for a medium-light, and heavier people considering a medium-firm.

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.

1 year guarantee is typical for the industry. This means you are guaranteed to have a trouble free experience for the first year or have your product replaced

800 Pocket springs is a compromise. It is a far better choice than an equivilent open coil product but is a little on the low end in terms of the volume of springs. Support should be acceptable, but if there is an option for 1000+ at a similar price, it is worthy of paying a little bit extra

This is a unique support layer unique to Dreams that helps to provide a soft and durable layer with fel-like properties that mould to your shape

Questions and Answers

Can you use an electric blanket with an ActiGel Harmonic 800 S mattress

Answer: Electric blankets can be used with all our mattresses however we do not recommend that they are placed directly on the mattress surface. In addition, using an electric blanket may alter the comfort grade of the mattress depending on the mattress type. We also recommend following all guidelines and instructions specified by the manufacturer of your electric blanket. Kind Regards, Dreams

I bought this mattress after trying the Sleepmatch machine in the store. My wife has neck and upper back problems relating to her spine. The old mattress did not do her back any favours and she always woke up feeling stiff. After sleeping for three weeks on the new mattress her neck and back issues, whilst still being evident, are no longer harsh. The stiffness in the morning is not as severe. I should have replaced the old mattress sooner .

Really comfy!

This mattress was very comfy straight away, our old mattress took quite a few weeks (and lots of sleepless nights) to break in so we were preparing for the same scenario. We were delighted therefore that is was immediately comfortable! It’s a median mattress with a thin soft layer on top, definitely recommend!

Bought for myself, so good bought one for my Mum!

I've had a slightly older version of this mattress for over a year and it's been so good I recommended it to my Mum and so far she said she's been having the best nights sleep she's ever had. It's a great price for the quality as I've never spent this much before on a mattress but it's been worth it so far!

Very comfortable

This is a very comfortable mattress! I replaced a sealy mattress with this and haven’t been’s a lot lighter to lift, so therefore makes bed making a lot easier for me..I love this mattress, I’ve slept much better since buying it! No aches and pains in the morning!

Extremely comfortable

We treated ourselves to a mattress after 8 years of 1000 pocket springs. We tried this one in the shop and it was very comfortable. One back sleeper and one side sleeper meant we were destined for a combination mattress. This did not disappoint and I highly recommend it.

So comfortable!

I decided to get the best mattress I could afford to buy and this one is perfect! Very supportive and comfortable! I was concerned that having a memory foam gel in the mattress would make me hot or even sweaty at night but it doesn't at all. Very satisfied customer!

Great value for money

I bought this mattress from the White City retail park last weekend and it is great value for money. The comfort was supportive without being too firm and I have had far improved sleep since I have had it. Great delivery as well - very friendly and respectful team.

Super comfy

bought thus mattress over a month ago and I never want to leave my bed. Super comfy! I suffer from lower back pain but haven't had any problems with this mattress. It's firm enough to support but still soft and comfortable when lying on my side. Absolutely love it

Like sleeping on a cloud

This mattress has provided a lot of good nights' sleep - it has a bouncy but firm quality to it, offering just the right amount of give while also providing impeccable support. I'm very, very happy with this purchase, well worth the price.


I bought this mattress a month ago and I cannot recommend it enough. I have severe restless legs syndrome and this mattress as meant that I can sleep peacefully due to the coolness of this mattress. Seriously it is worth every penny.

Professional Customer Service at Dreams

Existing mattress did not provide the support we required. The new TheroPur ActiGel Harmonic 800 resolved all our problems providing support whilst moulding into our natural body shapes. Guaranteed a peaceful night's sleep

Best night sleep in years!

We got this mattress a couple of months ago as a set with the mint 2 draw and the Verona mint headboard. Quality of sleep is so much better and the back support is exactly what I needed.

Excellent Mattress

I brought this mattress 3 weeks ago and I can honestly say that since having it my back which I've had problems with for years is so much better and I am sleeping so much more better!
