I can feel the springs through the top of the mattress with just my hands. Have woken up every morning with joint pain and not feeling at all rested. Really struggled to get a full-nights sleep without being woken up by being uncomfortable and in pain from the night before.
Delivery was also an unnecessarily difficult process due to not being able to communicate with the courier when I'd be home to receive it. I had to call Wayfair and explain that if I keep missing "attempts", due to them delivering while I'm at work, I'll have to cancel my order and go with a click-and-collect company. They soon delivered it my next day off - overall a week later than promised.
