The Millie & Jones Copper Summit 3000 has two layers of springs. 1000 full-height pocket springs in the base give the support, and 2000 small micro springs above them respond to the shape of your body more closely than foam alone. Reflex foam, 2cm of memory foam and a copper-infused layer sit on top, under a bamboo knit cover.
The result is a medium feel with more give at the surface than a single-layer mattress, which suits side sleepers who want their shoulders and hips cushioned without losing support underneath. The pocket springs move independently, so movement stays on one side of the bed.
At 27cm deep it is a full-depth mattress for a standard bed frame or divan, and deeper than many standard fitted sheets allow, so check your sheet depth. It is made in the UK, meets BS 7177 for fire safety and arrives rolled and vacuum-packed. Give it a day or two after unrolling to reach its full shape.

Will it fit your bed?
Choose the size your bed frame is made for: single 90 x 190cm, small double 120 x 190cm, double 135 x 190cm, king 150 x 200cm or super king 180 x 200cm. At 27cm deep, the Copper Summit 3000 is for standard beds, ottomans and divans. It is too deep for bunk beds, high sleepers and other raised beds, which need a much shallower mattress to keep the guard rail at a safe height.
Common questions
What do the micro springs add?
They sit above the main pocket springs and respond to smaller movements, so the surface follows your shape more closely. It gives a softer first feel while the larger springs below do the supporting.
Will my fitted sheets fit?
Choose fitted sheets made for mattresses at least 27cm deep, or deep-fitted sheets. Standard sheets made for 25cm mattresses can be tight.

Read more about how delivery works on our delivery information page.
Tell us within 14 days of delivery if you change your mind, then return it within a further 14 days. Return costs are yours.
For hygiene reasons we can't take back a mattress that has been removed from its sealed protective packaging, unless it's faulty. If it arrives faulty or damaged, you can reject it for a refund within 30 days of delivery.
To start a return, email support@millieandjones.co.uk with your order number. Full details are in our returns and refunds policy.
It arrives rolled. Unbox it soon after delivery, in the room it's going in. Lay it on the bed, cut away the wrapping carefully and let it unroll. Give it time to recover its full shape before you sleep on it.
Rotate it head to toe regularly so it wears evenly, and turn it over only if it's double-sided. A waterproof protector keeps it clean and fresh for longer.
