Tried for a month before finally giving in and resigning it to the skip. I would’ve arranged for return in ‘normal’ times.
It’s way too soft and really not suitable for purpose. There’s loads of roll together, and if you roll too close to the edge, you risk falling out. Also, it’s so ‘spongey’, it makes it very difficult to go from lying down to sitting, let alone getting up. 
All in all, I’m so disappointed to have wasted my money.
