I've had a proper feel of the iGel Front/Back Sleeper Medium Pillow in Bensons for Beds, and it is definitely aimed at people who like a firmer, more supportive pillow rather than something you sink into. Made from a memory foam and foam blend, this British-produced pillow is not only a healthy choice for your bed, but also offers a 1-year guarantee. Running my hand across it and giving it a good squeeze, it springs back quickly and keeps its shape, so you do not get that slow-moulding feel.
On my back it kept my head nicely level and I could feel it propping up the neck without forcing my chin down, which is exactly what you want if you wake up with a stiff neck. On my front, it still felt supportive but I did notice the firmness can push your head up a touch if you are used to a flatter pillow, so it will not suit everyone.
There are a couple of things to be aware of. If you are a side sleeper, or you like a plush pillow you can scrunch, this one is likely to feel too firm and a bit 'bouncy' under the cheek. Also, that 1-year guarantee is on the short side compared to a lot of pillows at this price point, and because it is foam it can feel a bit warmer than a light fibre fill if you already sleep hot.
Reviews are mixed. The older ones are mostly short and positive, and one owner bought it for her husband with bad shoulders who "finds this much better and more comfortable than normal pillows". Most of the recent reviews are unhappy, with complaints that it went flat, felt too hard or made neck pain worse. It is exclusive to Bensons for Beds.
