I bought one of the textured ones a few weeks ago to put on our spare bed (which isn't really spare, it's where I sleep as pregnant wife = not sleeping husband
) worth every cent of the $80 normal price - at 40% off grab two
. I was waking up sore every morning as the matress in there is too hard for me. the overlay makes it comfortable, and I don't wake up sore at all.
and don't be worried about the texture, you don't notice it when you are lying on it (although if you are like me and lie there moving your legs about, you will notice the lines and bumps, but nothing annoying...)
Clarks Rubber sell one that is almost identical for $300.
