I put Amazon’s bestselling £7 pillow to the test and love it — but this is the pillow I’d shop instead this Prime Day

I had little to no expectations when trying the Amazon bestselling Adam Pillow but it really did check all the right boxes. The £7 pillow was plush, medium-firm and supportive for my combination-sleeping style (side and back). However, if you’re struggling with summer heat like I am, go for the Simba Hybrid Pillow, now 20% off for Prime day.

While testing some of the best pillows of 2025, I understood that temperature regulation and breathability are core performance indicators, especially when recommending options for hot sleepers or anyone who struggles with night sweats. Yes, the Adam Home Pillow may be affordable, but it's unlikely to match up to the specialised cooling elements in the Simba Hybrid.

Need to make the most of the final day of the sale? Head to our Amazon Prime Day bedding deals, where we track the latest discounts as they drop. But first, here’s more info on the Simba so you can make an informed decision…

Simba Hybrid Pillow: was £109 now £87 at Amazon
The Simba Hybrid Pillow stands out in the market with its plush yet supportive fill, made with recycled polyester fibres and a contouring inner core layer filled with Nanocubes: soft CertiPUR foam cubes. Hot sleepers will love the Stratos cool-to-touch soft cover which means "no more flipping to find the cool side of the pillow". It also features an open mesh design on the sides to promote better airflow. You can now find the Simba Hybrid Pillow at 20% off in the Prime Day sale, taking the price of a standard size down from £109 to £87.

Adjustable comfort for all sleepers

One of our testers went hands-on the Simba Hybrid pillow, and found it to be comfortable for her combination-sleeping style (side and back).

The fully adjustable fill allows you to customise the feel according to your sleeping preferences, which means it is suitable for all positions (side, front or back).

All you need to do is add or remove the foam and fiber fill until you achieve the desired loft and firmness (Simba even provides a bag for storing excess fill). This makes it suitable for most sleepers.

A budget alternative...

Adam Home Pillow: standard pack from £16.99 from £12.99 at Amazon
Crafted from a plush down-alternative fill, the Adam pillow has a medium-firm support which will suit most sleeping styles. It comes in a quilted cotton and polyester outer cover filled with 3-D hallowfiber for enhanced comfort and cushioning. The brand also state that it's designed to promote airflow and be breathable, but it's unlikely to be as effective as an actively cooling pillow like the Simba Hybrid. You can now find a pack of standard pillows at 24% off which drops the RRP from £16.99 to £12.99.
