What an amazing comfy mattress. We gave it 48 hours to fully expand and breathe and its like sleeping on air. We only usually have a memory foam mattress but having both memory foam and coil is just fab. 
The delivery of the item was also amazing didnt expect it until the 5 days after ordering and it came within 2 days  
We are really pleased and happy with our purchase and would highly recommend and its great value too.
