This mattress is everything I’d hoped for. I’ve always had inner spring mattresses so I wasn’t sure how comfortable it would be, because I prefer a plush mattress. I purchased the 12 inch thinking that if it was too firm, I could add a topper, but there’s no need. It’s just the right amount of plush and support although I would have liked just a little more edge support. I love that it is charcoal infused as I have pets who often sleep on the bed with me and I think the charcoal will prevent a ‘doggy’ smell. It works well with the adjustable frame I purchased and if I choose to add a featherbed topper at some point, it wont impact the operation of the adjustable frame. I’m happy with it.
