In our experience, the materials and construction that go into this product can make it suitable for the following people.
A fast responding memory foam that is ideal for lighter and averagely weighted individuals and those who prefer a soft to medium sleeping surface.
Good for both side and back sleepers.
Reviews are mostly positive, with comfort and support the two things owners praise most.
Memory foam does not have the best breathability and so heat retention may play a factor.
Sizes are somewhat limited with no European sizing available.
A few owners found it firmer than the soft to medium rating suggests. One wrote that the "Top layer of memory foam could be softer".
New from Mattress Online comes the Memory Zone 3000, this is one of the retailers premium pocket mattresses that has of high-end memory foam and pressure relieving technology. The product is manufactured using a blend of micro springs and pocket springs paired in the base of the unit that, when combined with a deep and luxurious memory foam comfort layer results in a fantastic nights sleep. The Memory Zone 3000 Pocket Mattress is the ultimate mattress for sleeping and waking up refreshed. This premium foam mattress combines the support of customisable pocket springs with the pressure-relieving benefits of memory foam, resulting in a perfect balance between comfort and support.
When it comes to the comfort layer you get generous helpings of Memory foam. This comfort layer is a type of visco-elastic foam that is specially created to create conformability and pressure relief by softening with the warmth of your body, it works particularly well.
Onto the support layer and you get good quality pocket springs. These springs outperform many on the market with their improved design and better breathability over competing structures. Personally, we find pocket springs work better for full body contouring allowing for a more supportive nights sleep.
Owners mostly rate this one for comfort and support. One wrote that "it is so comfortable and supportive" and another called it "very comfy, beautiful and supportive". Value gets a mention too: one owner called it "well worth the money", though another wrote "Quality not the best and a little expensive". The feel is where opinion splits. A few owners found it firmer than the soft to medium rating suggests. "This mattress is harder than I thought it would be", one wrote, before adding "I have got used to it now and find it comfortable", while another said it "was very hard and uncomfortable". Another owner called it "nice and soft". One owner said it is "Not suitable for anyone or any two weighing more than MAXIMUM 18 STONES", and one reported that theirs "arrived scuffed".

Common questions answered by our team first, then questions shoppers asked the retailer, with the retailer’s own answers.
We've expanded on the specifications of the product to better help you understand its benefits.
A mattress with pocket springs will have individual springs that are each encased in their own fabric pocket. This allows the springs to move independently from one another, providing better support and durability. Additionally, pocketed springs are less likely to sag over time than traditional springs, making them a good choice for those who want a long-lasting mattress.
A mattress with a removable and washable cover can be a great way to keep your mattress clean and fresh. This type of mattress usually has a zipper or other type of closure system that allows you to easily remove the cover and wash it as needed. Many mattress covers are also machine-washable, making it even easier to keep your mattress clean.
Single side mattresses have a few pros and cons compared to traditional double sided mattresses. The main positive is that you do not need to flip, meaning a hassle free low maintenance product. The easy care nature does reduce durability slightly since there is less surface area utilised as there is no secondary comfort layer on the reverse.
Micro pocket springs are a type of spring that is often used in mattresses. These springs are much smaller than traditional springs, and they are designed to provide better support and comfort. Many people find that micro pocket springs make their mattress more comfortable, and they can also help to extend the life of the mattress.
A knitted cover offers a number of advantages over competing products. These covers are breathable which helps keep you cool and the mattress hygienic resulting in a cooler nights sleep that has you sleeping deeper for longer. Knitted covers also have the benefit of being softer than many others making them an ideal choice.
The foam-encapsulated border effectively increases the area usable for sleeping, allowing for edge-to-edge comfort and stability. Furthermore, this feature enhances the mattress's durability by maintaining its shape and providing consistent support across the entire surface.
These are springs that are individually wrapped in their own fabric pockets, allowing them to move independently from one another. This can provide a more comfortable and supportive sleep surface, as the springs can conform to the contours of your body more easily.
The memory foam moulds to the contours of your body, providing personalised support and adapting to your unique shape. This personalised fit creates a comfortable and supportive sleep surface tailored to your specific needs.
Meets BS7177: 2008 for domestic low hazard use. Testing covers resistance to a smouldering cigarette and a small flame the size of a match flame, not suitability for hotels or care homes.
Side sleepers typically benefit from a slightly softer surface to cradle their body's natural curves. A medium tension mattress offers this comfort without sacrificing support.
Fabric pockets surround individual springs, allowing each to move under pressure without pulling directly on its neighbours. These form the support system, per the listing.
Separate fabric pockets let springs compress independently. Each reacts to weight directly above it, with support across the body claimed for the combined spring unit.
Soft to medium is the advertised rating. This indicates more sink than firmer beds, offering a starting point for lighter people and those sleeping on their sides.
UK handcrafting is the maker's own claim, while National Bed Federation approval is a membership scheme auditing fire safety, clean fillings and honest labelling.
Handles offer grip when repositioning or rotating the mattress, while supporting its weight from underneath avoids putting excessive strain on their stitching.
Mattress Online calls this mattress vegan friendly, meaning no animal-derived materials such as wool or silk, though the label leaves out what replaces them.
A zipped cover can be removed and washed. Follow the care label's washing temperature when freshening the cover, so you can clean it without replacing it.
Made in the UK gives the country it was built in and little about quality on its own, so judge the materials, construction and guarantee separately.
Comfort layers are claimed to let shoulders and hips sink in and spread weight, with suitability depending on body weight and sleeping position.
The 28cm (about 11 inches) depth influences mattress sheet sizing and bed height. Frame measurements need checking against the full dimensions.
Delivered compressed in a roll, the mattress comes in a compact package and needs to expand after unpacking before use.
A five year guarantee comes with it. Check the retailer's terms for the fault criteria and for how to make a claim.
Memory foam softens with body warmth, moulds to your shape and slowly recovers.
Delivered rolled and compressed in a box, with only one side for sleeping on.
Five years of guarantee cover come with it.
