Doubleslee 3 Inch Gel-Infused Memory Foam Mattress Topper (Double) 135x190x7cm
Product description
If your mattress topper has become a bit of a let-down, this one is aimed at doing two jobs at once: adding a softer “give” with memory foam, and trying to keep things cooler with gel-infused layers. It’s marketed as an orthopedic-style topper for pressure relief, but the real question is whether that mix fits how you sleep (and what you’re hoping to fix).
On paper, the Doubleslee 3 inch memory foam mattress topper looks like a practical upgrade for people who want more comfort without replacing the whole mattress. The cover is washable (with a zip), it’s designed to stay in place, and it even has a double-layer concept so you can flip it for different comfort levels. Worth considering if your current bed feels too firm or you wake up with aching pressure points, though it may feel like a fairly “mid-range” comfort solution if you’re chasing serious, mattress-level transformation.
Key points
This topper focuses on cooling comfort and pressure relief through gel-infused memory foam, with a removable knitted cover for easier care. The double-layer design is meant to give you two different comfort feels by flipping it, while straps and anti-slip dots aim to reduce movement during the night. It’s delivered compressed and vacuum-sealed, so you’ll need a bit of patience to let it expand properly.
If you’re the sort of sleeper who changes position often, or you find toppers tend to migrate, the anti-slip approach matters. And if back pain is part of your bedtime story, the zero-pressure style of memory foam may appeal—though results will depend quite a lot on your body, your mattress base, and how much cushioning you actually need.
The essentials
The Doubleslee topper is a double bed size memory foam mattress topper, described as 3 inch thick and built with a gel-infused foam layer. Memory foam is presented as conforming slowly to your shape to reduce pressure points, then releasing more quickly so you don’t feel stuck. The gel beads are intended to help regulate body temperature for a cooler night’s sleep.
It also uses a double layer foam system. The idea is that you can flip the topper to switch between two comfort levels. That’s a nice feature if you’re unsure whether you want a slightly firmer or softer feel, or if your preferences change over time.
For day-to-day comfort, the knitted cover is described as skin-friendly and hypoallergenic, with a smooth surface. It has a metal zipper to make removal and washing easier.
What stands out in use
The cooling angle is the headline: gel-infused memory foam plus a cellular structure is claimed to help with temperature regulation. In practice, toppers like this are usually most noticeable if you tend to sleep warm, or if the mattress beneath you holds heat.
Pressure relief is the second big theme. Memory foam’s “zero-pressure” approach is designed to reduce pressure points, which could help if you wake up feeling stiff after sleeping on a firm surface. A small real-world example: if you’ve got a guest mattress that feels hard, adding this topper can make the top surface feel less abrupt under shoulders/hips, especially when you’re lying on your side.
Two more practical details help the experience: anti-slip dots on the underside and 4 elastic straps. If you toss and turn or frequently change position, you’ll likely appreciate anything that stops the topper from sliding.
Keep in mind, though, that a topper can’t fully replace a mattress with deep sagging or worn-out support. If the base is genuinely uncomfortable, this may just be a partial fix.
What you’ll notice day to day
Comfort feel and flipping
Because it’s built as a dual-layer system intended to be flipped, you’re not stuck with a single comfort profile. That can be useful if you’re between firmness preferences. Still, it’s not a guarantee that one side will suit everyone—if you’re very specific about how plush or supportive you want things, you may need a bit of trial.
Staying put
The combination of elastic straps and 3D anti-slip dots is there for a reason. Many memory foam toppers feel “cushioned” but can move around. Here, the aim is to reduce sliding so you wake up with the same alignment you went to bed with.
Temperature management
Gel-infused cooling can help, but it won’t make a warm room magically cool. If your bedroom runs hot, you may still want to rely on general ventilation alongside the topper.

Who it’s for, and who should skip it
It makes sense if you’re looking for an easier comfort upgrade: something you can add on top of a firmer spring mattress, or use as a guest bed/occasional sleeping solution (including caravan or sofa setups, as described). It also suits combination sleepers per the description, and it’s positioned as helping with lingering back pain.
It might not be for you if you need a topper to compensate for significant mattress collapse or very uneven support—toppers can soften, but they can’t rebuild support where it’s broken. Also, if you’re extremely sensitive to any “new foam” smell, you’ll want to plan ahead: it arrives compressed and vacuum-sealed, and you’re advised to allow about 72 hours for slight odour to dissipate and for it to fully expand based on room temperature and ventilation.
Final verdict
Buy the Doubleslee 3 inch gel-infused memory foam mattress topper if you want a removable, washable cover, a cooling-focused memory foam feel, and a topper that’s designed to stay in place thanks to straps and anti-slip dots. The double-layer flip idea is a practical touch if you’re trying to find the right comfort level without committing to a single feel.
Skip it if your mattress base is already badly worn or uneven, or if you expect a topper to deliver the kind of support changes usually associated with replacing the mattress itself. It’s a comfort-and-heat-management upgrade first, not a magic fix for every type of back pain.
