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.

PostureTech CS Springs
The unique PostureTech springs respond to your body weight to provide deep down support. As your body relaxes into the mattress and pressure is applied, the springs target the key areas of your body to offer support where you need it most. Not forgetting, the springs are twice tempered, making them resilient and trustworthy over time.
Soft White Fibres
Soft white fibre fillings which are made from 100% polyester. This type of mattress filling offers great recovery and is very durable, which means long-lasting comfort.
27cm Depth
This mattress is approximately 27cm deep.
Damask Cover
A mattress cover which is made from a breathable Belgian damask fabric.
Orthopaedic Support
Designed to offer a firmer sleep surface, providing targeted support for your back and joints.
Reinforced Edges
The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.
No Need To Turn
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
Pressure Relieving
This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.
Hypoallergenic
Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
Hand Tufted
Tufts help to secure the luxury fillings in place, helping the mattress retain it's fullness and plumpness over time.
Made in the UK
This item has been manufactured in the UK.
Fire Resistant - Low Hazard
This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.

Customer Review Summary

Many users appreciate the quality of the materials and construction, noting that the mattress feels durable and well-made. However, some find the firmness to be slightly greater than expected, which can be a double-edged sword; while it provides solid support, a few reviewers mention it might not be ideal for those who prefer a softer sleeping surface. Overall, this mattress is well-received for its blend of comfort, durability, and effective support.

The mattress was delivered by two polite and helpful men.I am pleased with the mattress but I wish it had handles to make turning it easier but I suppose I should have noticed this before ordering.
