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.

This mattress has the quality and feel of a waterbed. Instead of getting out of bed in the morning, you slide out. When you get in at night, you fear slipping off. This is not a medium firm mattress as sold.

Ive had sealy beds in the past. Recently I bought an adjustable bed for health reasons, but the mattress which came with it was awful! hence the reason I got a replacement sealy - it is just right. So far no complaints.
