We had been looking for an extra firm mattress for a while and so happy we found the Sealy Mellbreak at Mattressman. The mattress appears durable & good quality, no sag when sitting on the edge of the bed. Time will tell how hard wearing it is. It' quite weighty at over 30kgs so it takes two people to turn it, but you would expect that from a quality extra firm orthopedic mattress. My lower back pain disappeared after 8 days! If you're looking for an extra firm mattress, then I would highly recommend the Sealy Mellbreak. Good value for money.

You get what you pay for. Not a £100 purchase and not a £1000 purchase either but almost in the middle.My back pain started to abate within 2 night’s sleep on the new mattress and I started sleeping right through the night again. Great purchase and although not cheap , i would recommend this product very highly. Also , Andrew at customer services is a diamond. I called up with a query prior to my delivery and he completely put my mind at rest , 1st class service !!

I bought one of these for my son and was so made up with it that I bought one for myself too. It really is a lovely mattress, really good quality and a steal at the price. I'd also like to point out that customer service first rate. All in great company to do business with.
