Individually, the Simba Renew layers are incredibly soft, while the Aerocoil layer is much firmer, but with the airy coils and cotton covers, the pillow is breathable and doesn’t stifle – ideal if you sleep hot. The Simba Hybrid Pillow features nanocubes in a breathable cover. What exactly are Simba nanocubes? We tested the pillow for four weeks across warmer weather and colder nights, with testers that included a combination sleeper, petite sleeper and hot sleeper. The pillow delivered well for all, with superb levels of comfort, cosiness and most importantly spine alignment, especially for side-sleepers. Dedicated testing facility: We've tested over 180 products globally and now operate our own testing facility equipped with state-of-the-art equipment to analyse product performance.

The Simba Hybrid pillow may be very expensive, but it is definitely a high-quality pillow worth the cost. 💰 It has some pretty unique features: The previous version of the Simba pillow relied on Outlast technology, originally developed by NASA, to ensure optimal temperature regulation. If you’re a heavy sweater or enjoy your morning coffee in bed, we’d also recommend you opt for a pillow protector. ☕️The support on offer with the Simba Hybrid Firm Pillow is obvious from the minute you lay your head down. When all three layers are in place, the depth never feels ‘too much’ and the pillow offers a surprising amount of comfort alongside the firmness. At 5’2”, even our petite sleeper was comfortable, especially when sleeping on their side. The Visco-elastic open-cell foam has several tiny air-filled cells that help contour your head as you sleep, allowing you to find the optimal sleeping position.

The previous version of the pillow also used white nanotubes, while the new version uses blue nanocubes. What could we say but job well done!

Top Aerelle layer: This layer has mineral-enriched fibres that help dissipate excess heat and provide a soft feel. We are founding members of BRC climate action roadmap. Our mattresses are made in the UK from 100% recyclable materials. We refurbish or recycle old mattresses, rather than sending them to landfill. Our foam is CertiPUR® verified and free from dyes and heavy metals, while excess foam is repurposed into things like carpet underlay. But if you're looking for a customisable pillow with more of that traditional memory foam feel, you'd do better with the Emma pillow or the Nectar adjustable pillow. To wash your pillow cover, simply remove the inner pouch containing the nanocubes and pop the cover into the machine.
