      What the Sleep Expert thinks...

      "For firmer, clinical support, I steer people to the Miracoil Ortho. Zoned Miracoils stabilise the spine, hand‑tufting locks plush layers in place, and Eco Comfort fibres keep things cool. Perfect if back pain nags but you still want a bit of surface softness."

      The mattress is definitely very firm, but thats what I wanted. It took a few days to get used to but im very happy with it.

      This mattress is hard as a board - not firm in a supportive way, rather feels like sleeping on a flat surface. I had back pain before adding a topper (and with the price I paid I do not think a topper should be a necessity). Furthermore I was incredibly dissatisfied with the return/exchange process that costs 99 pounds and requires a 50 night minimum trial or a two week turn-around and a *self return* to the warehouses. This was in the fine print and entirely unknown to me when I purchased the mattress. If I had known I would not have bought a mattress through this company.

      Mattress is slightly firmer than the same model we had before. But for sure its ok.
