For anyone tired of flipping pillows to find the cool side or plumping them against a persistent neck ache, Simba’s hybrid pillow offers a different approach. Instead of a single block of memory foam, it is filled with hundreds of open-cell foam ‘nanocubes’. The result, according to a reviewer who tested it nightly for 10 months, is a pillow that combines the cloud-like feel of down with the pressure-relieving support of foam.
The nanocubes are made from open-cell foam containing tiny sealed air cells, giving them a springy bounce closer to feather or down than traditional polyurethane memory foam. In firmness, the pillow sits between feather and memory foam, with a natural-fibre feel comparable to wool. It provides ample support without letting the head sink to the mattress, particularly when all the cubes are retained and fluffed occasionally.
A key feature is adjustability. The outer and inner covers unzip, allowing the user to add or remove handfuls of nanocubes to fine-tune height and firmness. The reviewer, a side-front sleeper, moved cubes from the base to the top to create a wedge shape with a low neck profile. Front sleepers might remove cubes to lower the height, while back sleepers can redistribute them weekly to maintain loft.
Temperature regulation is another highlight. One side of the cover uses Simba’s ‘stratos’ technology, with microcapsules that absorb, store and release body heat. The other side is made from breathable, ethically sourced cotton. A thick mesh stripe around the middle promotes air circulation around the cubes. The reviewer gravitated to the climate-controlled side and reported no uncomfortable nights.
The synthetic fill makes the pillow suitable for allergy sufferers, and the microfibre layer between cubes and cover is hypoallergenic. The removable cover is easy to wash. After 10 months of use, the reviewer rated this hybrid pillow above all others tested, praising its comfort, adjustability and climate control.
