While the Sleep Number’s airbase will allow you to dial in your desired level of firmness, the 7-inch foam comfort layer will leave this mattress on the soft/plush side. That’s why, for those looking for a firmer bed, it may be difficult to justify the hefty price tag of the i10.
However, other reviewers have mentioned that by adjusting to a firmer sleep number setting, they were able to cancel out the soft foam enough to give them the feel they desired, and they didn’t feel like they were sinking too deep into the mattress.
That’s why the Sleep Number 360 i10 could be a good choice if you and your partner have drastically different preferences when it comes to mattress firmness.
You may be a side sleeper looking for something on the plush side, while your partner is a stomach sleeper who prefers a solid brick wall. While the i10 can’t turn into a brick wall, it can give your partner the firmness they desire while providing you with the softness you need.
That being said, this works better for couples who like to keep their distance when they sleep.
Rolling too close to your partner or cuddling in the middle of the bed may lead to some discomfort if the sides are set to different Sleep Numbers.
