Mattress is good, but the smell of sheep was really bad hence dropping a star (sorry for that). I am aware that a smell is normal, however this was really strong so much so you could smell it as you walked upstairs. We had windows open, stripped the bed every day for 3-4 weeks, aired the mattress topper and protector outside as well. Bearing in mind our previous mattress was a similar good quality wool product which also had an odour, but not as strong and didn't last as long either. The mattress material still smells, but not as bad as it did. I would like to say that we are very pleased with the comfort and you can see it is a well made quality mattress. The service we received was first class. We would be happy to use Mattress Online again when the need arises.

To your touch it feels like a soft mattress, but when you lie on it, it feels like a medium, which was what I wanted. To lie on it is bliss and my sleep is much deeper. Thank you.
