The Serta Icon Plush feels flimsy, bouncy, and spongy. Questionable spinal support. Comfortable but has some partner disturbance.

The King Koil Chiro Flex 5 Medium is comfortable with decent spinal support and minimal partner disturbance.
King Koil Chiro Flex 5 Plush (Discontinued)
The King Koil Chiro Flex 5 Plush has that immediate sinking feeling and doesn’t support the body well. It is soft and spongy so it is comfortable but spinal support is questionable. Partner disturbance appears minimal.
Serta iContour Plush (Discontinued)
The Serta iContour Plush has a sinking feeling but once it settles it still gives decent support. Has that “dense” feel to it as well. Minimal partner disturbance.
Serta iContour Medium (Discontinued)
The Serta iContour Medium feels solid and quite firm. Good spinal support. No partner disturbance. A very good mattress but a little pricy.
Serta iContour Firm (Discontinued)
The Serta iContour Firm feels firm and solid. Very good spinal support. It may be too firm for some but it is still reasonably comfortable and has virtually no partner disturbance.
Serta Avant Garde Sofia (Discontinued)

Sealy Posturepedic Invigorate Medium (Discontinued)
The Sealy Posturepedic Invigorate Medium definitely has some partner disturbance and feels a bit springy and bouncy. On the other hand it is comfortable and has decent body/spinal support.
Sealy Posturepedic Invigorate Firm (Discontinued)
The Sealy Posturepedic Invigorate Firm feels springy and bouncy and has some partner disturbance. Although it’s reasonably comfortable, nothing remarkable here.
Tempur Nirvana Balance (Discontinued)
The Tempur Nirvana Balance is quite firm but still fairly comfortable. Very good body support and very minimal partner disturbance. Won’t be suited to everyone but a very good mattress in terms of spinal support.
Beautyrest Black Hybrid Charlotte (Discontinued)
The Beautyrest Black Hybrid Charlotte feels a bit soft and spongy and although the build quality is no doubt of a high standard, the spinal support seems questionable. Partner disturbance seems minimal but it comes with a big price tag. Keep looking.
