The Four Feels standard version (without the mattress top) is a very nice firm feel with a subtle bounce and very good spinal support. This mattress is very versatile.
Orthokinetic Classic Plush (discontinued)
The Orthokinetic Classic Plush is actually quite dense for a plush which gives it good spinal support and it is still nice and comfortable.
Orthokinetic Classic Medium (discontinued)
The Orthokinetic Classic Medium has a lovely mix of comfort and support. It has a very nice, subtle bounce to it and edge support is reasonable.
Orthokinetic Classic Support (discontinued)
The Orthokinetic Classic Support has a firm yet bouncy feel to it which feels very supportive for the spine. Edge support is good and partner disturbance is minimal.
Posturepedic Enhance Platinum Plush (Discontinued)
The Posturepedic Enhance Platinum Plush is very comfortable but still feels flimsy and unsteady. It supports the spine fairly well and although edge support is good, there is still some partner disturbance to contend with.
Exquisite Lancaster Medium (Discontinued)
The Exquisite Lancaster Medium has that typical Sealy top layer that feels ‘unsteady’ and this creates some partner disturbance. This model is not particularly comfortable.
Exquisite Lancaster Ultra Plush (Discontinued)
The Exquisite Lancaster Ultra Plush has a very deep top layer which feels quite light and ‘cloud-like’ which is what you would expect from an ultra plush version.
Orthokinetic Grandeur Plush (discontinued)
The Orthokinetic Grandeur Plush feels soft, comfortable, and has good spinal support as well. The build quality of this mattress is excellent for the price.
Stellar 22 Medium (Discontinued)
The Stellar 22 Medium has a very unique feel – it is hard, dense, and bouncy at the same time. Spinal support is very good but the level of comfort and weight absorption may not suit everyone’s taste.
Hallet Plush (Discontinued)
The Hallet Plush feels cheap and flimsy and subsequently, this creates a lot of partner disturbance. The spongy pockets on the top layer give a very basic level of comfort and support.
Acclaim Extra Firm (Discontinued)
The Acclaim Extra Firm feels flimsy, unstable, and very bouncy. The top layer is hard and firm which may suit some but overall not comfortable at all. There will be some partner disturbance with this one as well.
Acclaim Firm (Discontinued)
The Acclaim Firm has a very bouncy feel to it and so partner disturbance will be an issue. Edge support is good but pretty basic overall. About what you would expect for the price at most retailers.
