We've had a Saatva King for two and a half years now. We have the "Plush Firm" and I sleep on my back or sides. My wife sleeps on her sides and stomach and it's been great for both of us. It's also held up really well. We haven't rotated it tbh, and there isn't "dent" where our bodies are laying every night. It looks basically brand new. We bought a "firm" for our 5 year old son at the time and he loves his as well. The firm is decent step up in firmness compared to the plus firm. Unless you need a mattress that doesn't have much give at all, get the plush firm. My parents bought one about a year ago and love theirs as well.
