What the Sleep Expert thinks...

"PostureTech CoreSupport springs sense your weight, firming under heavier areas while staying comfortably responsive elsewhere. This makes this mattress ideal for improving your posture as you sleep, and I particularly love how these springs adjust quickly to your movements to maintain the most consistent level of support. Paired with a hand‑tufted surface and breathable polyester comfort fibre, the Ortho Plus Essential delivers dependable, medium‑firm support that keeps your spine aligned and the mattress feeling fresh night after night."

The Sealy Ortho Plus Essential mattress is the perfect choice if you're looking for a firmer, supportive feel.

Inside this mattress is Sealy's unique PostureTech Core Support spring system that is weight responsive, giving you support where you need it most. The springs get firmer as pressure increases to offer deep down support that’s longlasting.

The traditional hand tufted sleep surface provides a firmer feel whilst offering added durability.

The mattress is also single sided. Simply rotate it from time to time to improve its lifespan.

Customer Review Summary

Customers have generally expressed strong satisfaction with the mattress, often describing it as both comfortable and supportive, which has notably enhanced their sleep quality. The high-quality materials and solid construction have also received praise, with many feeling it offers excellent durability. However, some reviewers found the mattress to be firmer than they anticipated, a factor that not everyone appreciated but was seen by many as beneficial for providing strong spinal support. Overall, this mattress is well-regarded for its blend of comfort, quality, and support.
