What is Celliant?
Celliant is a branded textile technology that incorporates mineral particles into fibers or coatings. Its maker, Hologenix, says the materials absorb energy from body heat and emit infrared energy. It is used in some clothing and bedding, including selected mattress covers.
That description is a manufacturer explanation of the technology. It does not by itself establish that a particular mattress improves sleep, circulation or athletic recovery for every buyer. Fit, pressure relief, temperature preference and return terms remain central to choosing a mattress.
What the research actually says
A small study of Celliant shirts examined skin oxygenation and grip strength in healthy volunteers. The researchers reported changes in those measures after short periods of wear; the paper disclosed sponsored research funding from Hologenix. It did not test a mattress cover or show that sleepers recover faster.
Hologenix also lists a pilot study of a Celliant mattress cover in people with chronic back pain. Pilot research can inform further study, but a small or specific sample does not establish a general benefit for all sleepers. A randomized pilot of infrared-emitting pajamas examined sleep with a different product; results from other textiles cannot automatically be applied to Celliant mattresses.

Where it appears in mattresses
Bear says Celliant-infused covers are available with several of its models. Construction and upgrade choices change, so confirm the current cover for the specific size and model. A mattress may also contain foam, coils, phase-change material or other features that affect its feel independently of the textile.

How to evaluate the upgrade
- Check whether the fabric is included or an optional paid upgrade, and what a replacement cover costs.
- Compare firmness, spinal support, pressure relief, motion isolation and edge support first.
- Read the current trial, return fee and warranty conditions for the exact retailer.
- Consider heat from the whole bed, sheets, room temperature and personal preference; Celliant is not a guarantee that a mattress will feel cool.
- Ask whether a protector affects the feel or care instructions. We cannot quantify how a protector or sheet changes any claimed infrared effect.
The original article also featured a PureCare product. Availability and composition may have changed; check the label of any current listing.
Comparing alternatives
For a practical comparison, try beds with and without specialty covers in your preferred position. Choose a surface that feels comfortable over time and supports your body; a textile claim should not outweigh an uncomfortable mattress.

If sleep problems, pain or recovery concerns persist, seek individualized medical advice. A bedding textile is not a substitute for diagnosis or treatment.
Common questions
Does Celliant guarantee better sleep?
No. Research is ongoing and the effect of a specific mattress cover cannot be assumed for every sleeper.
Is Celliant the same as an electric heating pad?
No. The textile is marketed as a passive material; it does not require a power cord.
Is every Bear cover the same?
No. Check the current specification and upgrade selection for the exact model.
