This is THE MOST COMFORTABLE mattress I have ever had in my entire life and I am ancient! It is of the highest quality and, at this price, represents really excellent value for money. It is at the higher end of the firm scale which suits me very well being supportive without being too harsh or leaving me feeling like I have slept on a board. Quite unusually, there was no 'getting used to' this mattress as there can be sleeping with a new one. Within seconds of getting into bed for the first time with the new mattress, I knew it was a good purchase. I cannot believe how well it retains its shape and looks immaculate after the longest of kips. Also, for some reason neither the fitted sheet or the duvet, duvet set and quilt move at all during the night, the bed hardly needs made at all every morning. I have been sleeping SOOOOOO much better with this mattress on my bed, genuinely getting a better quality of sleep, sleeping longer and not continually waking through the night. The only downside is that it it is so comfy and cosy I never feel like getting up in the morning! I would recommend this product without hesitation or any caveats. Best wishes to all!. David Gordon.
