The Chiro Extend 200 (Plush) feels nice and comfortable and spinal support is still quite good for a plush version. Unfortunately it does feel a little unstable.
The Chiro Extend 300 (Medium) has a nice firm, bouncy feel to it and it offers good comfort and good spinal support. Partner disturbance won’t be too much of a problem.
The Chiro Extend 400 (Firm) feels firm and has very good spinal support. Has a bouncy feel to it which actually feels a little unstable, surprising considering the price.
The Chiro Reach Deluxe (Plush) has a ‘deep, spongy, bounce’ to it and a nice combination of comfort and spinal support. Partner disturbance is present but minimal.

The Chiro Motion 500 (Extra Firm) is very firm and has a slight bouncy feel to it. Would only suit those who prefer a very hard and firm feel. If that is you, it is a decent mattress.
The Chiro Motion 400 (Firm) has a nice little bounce to it and partner disturbance is minimal. Quite a firm feel so if you want a bit more comfort, try the Chiro Motion 300.
The Chiro Motion 300 (Medium) is quite comfortable and has good spinal support. Build quality is reasonable and a restless partner shouldn’t bother you too much at all.
