I've been using this mattress for about a month now and there's a clear depression where I'm sleep. Not huge yet, but enough to create the "climb to the middle" feeling. Honestly, wasn't expecting this to happen so fast. But for the first few weeks, it was amazing.
The bed is ok. We've had it for a month or so. Doesn't seem to stay cool as advertised and may start to sag. Wasn't sure if there is anything we can do about that.
I've had my Ghostbed for two weeks. The order process was easy, delivery was quick, assembly went smoothly and I'm simply loving how comfy the bed is. No more pain in my shoulders or lower back upon awakening. We shall see if the mattress holds up well over time without sagging.
This bed is absolutely amazing. It was cool and opened just like in the videos (this was very important to me.) Sleep wise though it's amazing. I have slept so well every night since buying it. I would recommend it to anyone who has trouble sleeping.
I bought different sets of sheets for our bed think they were the sheets but actually our mattress got smaller. I have to constantly pull the sheets back over the mattress during the night.
