Why Our Sleep Experts Loved It

becky says

The iGel™ Advance 3500i Plush top Mattress from Bensons for Beds has been designed with the needs of modern sleepers in mind. With it's temperature-regulating technology that allows you to keep cool when it's hot and keep warm when it's cold, it's the perfect sleep aid for those who suffer from aches and pains in their joints. It also provides excellent support, thanks to its dual layer pocket springs encased in foam for premium support. The 3500i dual layer pocket springs provide comfort and durability, whilst the innovative iGel™ Advance beaded gel provides pressure relief and helps relieve aches and pains.

So who will find this type of mattress suitable? Quite a lot of people frankly, in part thanks to that medium tension on offer through those great quality pocket springs. See, pocket springs are already the best (in my opinion) spring type you can get in a mattress. Combine that with the medium tension and you create widespread appeal as the product will likely suit most average weighted side sleepers, back sleepers and stomach sleepers. The result is a well-rounded product that does a big of everything really well. It's the same story with the graphene infused memory foam which keeps you up to 7 times cooler than traditional foam and in a generous helping too giving you all the benefits of memory foam but with non of the downsides. I really like gel foam options like the one on display here and it works really well.

What about who this product won't suit? From a comfort and support perspective that window is very narrow indeed, but what about from a cost perspective? That's where things get rocky for this product and indeed most of the iGel range. Truth be told this is a premium mattress at a premium price point and not for a penny less. The result is many people may want this mattress, I do too, but not many will be able to afford even with Bensons for Beds generous finance options allowing you to pay later.

The mattress is also made with a more environmentally sustainable formula than your average foam mattresses. It's easy to care for too, as it's non-turn product, meaning that you can rotate the mattress every now and then but you can be less stringent than is typical. 

Being both antibacterial and hypoallergenic, this is the mattress to have if you suffer from allergies. Same too for the environmentally conscious, featuring  second life textiles and 100% recycled PET.

Honestly, 3500 pocket springs, multiple firmness options and a unique iGel comfort layer is the complete package that you can get within a mattress, throw in a unheard of 10 year guarantee for free as standard and you won't need to look elsewhere for your next mattress because this is it.

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews.

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.
  • Turning on mattress
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • 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 iGel Advance 3500i Plush Top Mattress Great?

Luxuriously indulgent plushtop layer – for optimum levels of surface comfort?

The plushtop layer gives enhanced comfort over traditional comfort layers. Think of a plushtop as the ultimate in comfort layer, deeper than most other rivals and luxuriously soft, plush tops have surpassed pillow tops in quality and convenience.

Powered by an extra deep 7.5cm of iGel™ Advance Graphene Technology – intelligent temperature regulation helps you sleep not too hot, not too cold, just right

The iGel™ Advance foam has an advanced and breathable design that provides a comfortable and cool sleeping environment. The system features a comfortable gel layer that helps promote airflow for enhanced comfort and a better sleep experience.

iGel™ Advance Graphene - 7 times faster heat transfer than standard foam, Graphene is cleaner than synthetic additives

The biggest downside to traditional memory foam is around heat retention. The iGel graphene is a unique design that sees better performance and enhanced cooling via the heat transfer over standard foam.

iGel™ Advance intelligent temperature regulation - proven to absorb, store and release heat to help you remain at the ideal sleep temperature – within the 35° to 37° Celsius comfort zone

iGel isn't just about being 7 times better for heat regulation over memory foam, it's also about the intelligent temperature regulation beyond that. See, being too cold can be just as disruptive as being too hot. Fortunately, the iGel formula keeps you at a temperature that promotes deep sleep consistantly.

Nothing feels quite this good - with iGel™ Advance patented know-how, exclusively at Bensons for Beds, we’ve perfected a feel that’s like nothing else

iGel Advance is the name for the new range of iGel mattresses, all of which feature graphene gel foam materials that perform similar to memory foam but without many of the downsides around heat retention and heat build up.

Opulent super loft and super soft stretch-knit cover - luxuriously soft and breathable, with eye-catching centre panel design

Soft and stretch knit covers are standard for many of the mattresses you see today. The benefit being that the breathable design ensures you remain cool while you sleep which means less sweat followed by a more hygienic nights sleep.

3500 premium pocketed springs - for individual comfort and support, with reduced partner disturbance

When it comes to pocket springs, the higher the number generally the better. See, the more springs you have in a confined area, the better contouring and support you will get in that area. 3500 springs is toward the top end and will give premium support that will react to each of your movements.

AdvantEdge™ superior edge support – premium support along the edge of the mattress, for added durability and to increase the mattress sleeping area

Unique to iGel mattresses, the AdvantEdge™ platform is available in part thanks to the premium pocket spring system housed within. With additional edge support, you get a firmer edge regardless of tension meaning you are able to spread yourself over each and every inch of the mattress allowing you to utilise more of the product and spread out while you sleep.

Soothing and supportive pressure relief - iGel™ Advance can help reduce aches and pains, with pressure relieving Gel crystals for targeted support where your body needs it most

Another on the benefits of the iGel Advance range. The combination of high quality pocket springs paired with high quality gel foam gives zonal support that targets each area of your body wit individual contouring and adjustment. The result is that no part of your body that is making contact with the mattress is going to be without contrasting pressure and support.

FreshNow™ advanced moisture wicking - helps to prevent waking caused by humidity, for an all-night fresher feel

New to the range but growing in popularity comes the new FreshNow™ material utilised in many of the more premium mattresses from this retailer. The FreshNow™ remains soft and luxurious to the touch but features additional moisture wicking features that will keep you cool while you sleep.

iPure™ - our cleanest formula foams and fibres, with more recycled PET polyester fibre content (80%), and fewer synthetic additives

Specific to the iGel range,  the mattress is CertiPur™ accredited thanks to the iPure™ mattress construction which features significant polyester fibre content that is cleaner than competing products, made up of loss synthetic additives that make for one of the cleanest formula foams and fibres available.

In partnership with the BCA (British Chiropractic Association) - the largest and longest established association for chiropractors in the United Kingdom

A BCA partnership helps to highlight the quality of the support layer on offer in this mattress. A BCA partnership helps highlight that the mattress has been designed and tested to chiropractor standards resulting in better back and neck support.

Mattress depth – 37cm

When it comes to mattress depth, the deeper a product is, the more room it has for deep fillings that will have you sinking into the mattress. 37cm is one of the deepest we have ever seen and will certainly require deep fitted sheets to cover.

2 comfort choices – Mediumor Firm

This mattress is available in the two most popular tensions of medium and firm. Consider the medium tension if you sleep more on your side or are a combination sleeper, while primary back sleepers, or, those with a higher BMI, should consider the firmer offering.

Easy Care – No turn mattress?

A no turn mattress basically means that it is one sided and does not require flipping over. There are pros and cons to this depending on your circumstance. First, the pros are that there is far less maintenance and hassle as you do not have to flip every few months, this can be more of a pain than you think given the weight of the product and also whether or not it features turning handles. There are a few cons however, namely when it comes to wear and tear. A non-flip mattress has the comfort layer on the top and so your maximum surface area is halved over a double sided mattress which can increase wear and reduce lifespan. Nowadays quality standards prevent this from being too much of an issue and expected lifespan of a one-sided mattress is still a fairly long time.

Free 10 year guarantee – for total peace of mind?

A 10 year guarantee shows just how much faith a manufacturer and retailer have in their product. The industry is still plagued by far too many 1-year guarantees and this one helps highlight a change toward better standards and consumer confidence.

Customer Reviews For The iGel Advance 3500i Plush Top Mattress

Based on 24 reviews

The mattress has taken about 2 weeks to start settling in. It moulds nicely to us lying down and were used to rolling over or getting up out of bed as it's a totally different feeling to a normal mattress. For 1700 it was a big purchase and we probably would say its a bit pricey for what it is but we're still glad we got it as it's a huge improvement to the previous standard spring mattress we had. The I gel cooling is definitely a gimmic. It's just lots of foam. A very deep mattress and you will need extra deep fitted sheets.


So comfy worth every penny. Although I panicked I had ordered the wrong one when it arrived. When putting on bed I sat on mattress and it was harder than the kitchen table. Left it 12 hours and it was exactly as in the showroom! Brilliant and pillows and mattress protector too so happy thank you!


I brought firm style as back issues. It is a thicker mattress with built in topper. the comfort is great. sleep so much better than any other mattress I have previously owned. The 10year guarantee gives peace of mind. Recommend this mattress


Thought it would take a little while before getting used to the mattress but no such issue, really comfortable and even my husband who didnt think we needed a new mattress is really happy with it .


This product is solid and I highly recommend it for people who suffer with back or neck pain. Also very comfortable for a good night's sleep among other things.


I was a bit wary of the igel after i bought it but after sleeping on it i love it i got the firm mattress with the igel topper and its great
