The Medicoil Ultimate Contour has a spongy top layer which is fairly comfortable but the top layer feels somewhat unstable and spinal support is compromised.
Medicoil Supreme Contour
The Medicoil Supreme Contour immediately feels cheap – you can feel the springs with any major movement. Partner disturbance will also be an issue here.
Sleep Right
The Sleep Right has decent support but not particularly comfortable. Feels unsteady and partner disturbance will be an issue. Pretty cheap and nasty, maybe for the guest room.
