Sleep Number Bed 😬

I hate our sleep number bed we just got - it’s a split king on an adjustable base and feels like I’m sleeping on an air mattress. There’s also no support along on the edges of the mattress, the two twin xl mattresses do NOT stay connected at all, there’s a huge gap down the middle of our beds and it is just so uncomfortable… I think because it’s just air and lacks foam/springs/whatever makes other mattresses comfy.

We NEED a split king and adjustable base - what other beds would you recommend? I’m open to it not being an adjustable mattress but it needs to not come apart with the split down the middle and be comfy!

Thank you!
