## Description

This hybrid mattress combines gel memory foam with individually pocketed springs to offer medium firmness and zoned support for a double bed measuring 135 x 190 x 23 cm. It is intended for sleepers seeking pressure relief and spinal alignment while maintaining breathability and motion isolation for two people.

## Key Points

The mattress uses a 7-zone pocket spring system to target different areas of the body, aiming to support the shoulders, lumbar region and hips with varying spring tensions. The gel-infused memory foam layer helps dissipate heat and adds contouring comfort without excessive sinkage. 🛏️

Materials carry CertiPUR-US and OEKO-TEX references according to the original specification, which indicates attention to non-toxic and low-emission foams and fabrics. The cover is a 3D printed knit that allows airflow and manages moisture, helping the surface feel cooler overnight. There is an enhanced edge support design with firmer springs around the perimeter to reduce sagging when sitting on the side of the bed. 🌬️

A compressed roll-pack format is used for delivery, taking between 24 and 72 hours to fully expand after unpacking. Users are advised to be careful when cutting the outer wrapping to avoid damaging the fabric or injuring themselves, as noted by the manufacturer.

## Benefits

This mattress balances contouring and resilience so it can relieve pressure points while keeping the sleeper supported. The pocketed spring unit minimises motion transfer, making it easier to avoid disturbance from a partner’s movements during the night. The gel memory foam aids temperature regulation, which may be preferable for people who sleep warm.

The combination of certified materials and a breathable top layer supports long-term comfort and durability according to the product details. Consider that firmness perception is subjective and may vary by body type and sleeping position. Also, the mattress requires a short break-in period after unboxing as the foams settle.

## Usage Recommendations

Place the mattress on a compatible slatted base or a solid platform that provides uniform support and ventilation.

For regular maintenance, rotate the mattress head to foot periodically to even out wear, although flipping is not recommended given the sided construction. 💤 .
