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.

Rated Excellent
This mattress has largely been praised for its high-quality construction, comfort, good support, decent firmness, and excellent value for money. Users mentioned its robust make and that it helped with back pains. A noticeable number of users also compared it favourably to other mattresses they've owned, frequently highlighting Sealy as a trusted brand. However, some customers found it not as firm as they expected and felt the quality varied.
