Will the Aireloom Preferred M1 Plush hold up over time?

We bought an Aireloom Preferred Luxury Firm (called the Amargosa Luxury firm at our local store) bed and I feel like it’s a little too firm for my hips when I side sleep and a little too unsupportive for my back. Tried the Bishop Plush (think this is their Preferred Luxetop M1 Plush line) and it seemed both softer and more supportive. Does anyone have this bed to recommend or speak to whether it holds up?

Plush would be better for side sleeping. They also sell an Aireloom latex mattress cover that will soften up you mattress.

I felt the M1 Luxetop Firm was incredible in the store. Im 230 pounds at 5ft 11in.

Check King Koil Pure Bliss Latex (Brook or Genesis). National brand. Feel incredible for side sleeping.
