Enjoy deep, restful sleep with the CoilSync Mirapocket 1000 Mattress from OneThird. Designed to deliver both comfort and support, this mattress features 1000 individually responsive Mirapocket springs and breathable, allergy-friendly fillings—perfect for waking up refreshed and pain-free.

Mirapocket Spring System

OneThird’s exclusive Mirapocket technology uses 1000 individual springs that move independently to offer targeted, pressure-relieving support. This system ensures optimal spinal alignment, reduces motion transfer, and provides edge-to-edge support, creating a more stable and supportive sleep surface—especially ideal for couples.

Support for Back, Neck, and Shoulders

Whether you sleep on your back, front, or side, the CoilSync Mirapocket 1000 is designed to ease pressure points and help reduce common aches and pains. If you're struggling with neck, shoulder, or back discomfort, the responsive spring system helps promote better posture and a more comfortable night’s sleep.

Breathable & Allergy-Friendly

Finished with a soft knitted micro-quilted cover and filled with 100% polyester fibres, this mattress enhances airflow and is resistant to allergens—promoting a cleaner, healthier sleep environment.

Is a medium firm mattress right for me?

With a medium firm feel, this mattress offers the ideal balance of cushioning and support. It’s a versatile choice for all sleep positions and is especially well-suited to couples with different sleeping preferences.
