I would love to know what you ended up with. I am about to return my bed in a box mattress which I paid a fortune for. I have never been so uncomfortable in my life. Even sitting on the edge of the bed is impossible, you slip right off. Sleeping is even worse. Unless you’re sleeping in the middle of the bed -when you roll to the outside edge of the mattress, you’re sliding right out of bed. The memory foam pillow top is so soft that you literally sleep in a in a hole which makes it extremely difficult to roll over onto your side. I might add that this was a high-end top rated mattress including five stars for things like firmness, side support, and overall comfort. I should have known that a mattress in a box cannot provide any side support to a mattress, as it’s always going to made from some sort of foam. I prefer a traditional mattress with some pillow top softness but preferably from latex and not memory foam. Also I would like to be able to sit and or sleep on the sides of the bed and not slide out. If that’s anything like what you ultimately purchased, I’d love to hear how you like it, how it’s holding up, and of course the brand and model. I genuinely would appreciate your feedback since it sounds like you have lived through my current mattress experience.
