Wrapped in BioCare fabric
The Best of Both™ cover is made with BioCare, a fabric developed by Boyteks. Fine metal yarns are woven right through it, forming a conductive net that is part of the fabric itself.
- Woven-in metal yarns: The protection is in the weave, not a surface treatment.
- Anti-static: Helps reduce static build-up while you sleep.
- Electromagnetic shielding: Boyteks reports the fabric reduces electromagnetic waves reaching the body by 98.5%.
BioCare is a Boyteks fabric technology. Figures are as reported by Boyteks.

Firm, Medium and Plush describe feel. They don’t describe how well a mattress supports you. This is how the support systems compare.

Why we don’t recommend foam or fibre as a core: they make good comfort layers, but as a support core they compress under pressure, retain heat and fatigue faster than a spring system.
Ratings are an internal assessment, not independently verified. A qualitative comparison of support-system design, assuming comparable mattress quality. Comfort layers, materials and overall construction also influence real-world performance. “Recommended” reflects the Support-First philosophy, not a judgement of any individual mattress.
MiraCoil® for structural alignment and edge-to-edge stability, Pocket Coil for contouring and pressure relief, combined in a single engineered system, always paired with Calibrated Feel™.

Questions About Perfect Sleeper X
Single or double sided?
Single sided mattresses have one sleep surface and never need flipping. Double sided mattresses are finished on both sides, so they can be turned over.
Do I choose a feel?
No. Each model has one calibrated feel, built in. You choose the spring system and your size.
