It’s hard to give a proper review since I’ve only had the mattress for about 4 days now, but first impressions are FABULOUS! It fully expanded in seconds, upon cutting into the vacuum sealed wrapping, and felt incredible right away. My partner and I gave it a full 24 hrs before putting it to use though. After our first full nights sleep, I have to say, the difference in my quality of sleep is immediately noticeable. I haven’t tossed and turned, and my sciatica in the morning isn’t as apparent (which is great being a dancer and being able to hop out of bed without pain). My partner has nicknamed our new mattress “Heaven” if that helps make your decision. I’m curious to see how it holds up in the coming months to determine whether or not the bang is worth the buck, but we are definitely happy with week one.
