Perseus Medium-Soft Mattress

Cooling Comfort and Responsive Support, Built Layer by Layer

Introducing the Perseus, a 26cm deep, medium-soft pocket sprung mattress made by Limelight Beds, a premium UK bed and mattress maker. It combines a plush, cushioned feel with proper structural support, so you get the comfort of a softer mattress without losing the support your back needs. Cooling gel memory foam, high-density support foam and foam-encased pocket springs are all built into one mattress. It's finished with a smart dark side panel and fresh lime-green piping, and it comes with a 5-year guarantee for peace of mind.

Seven Layers, Each With a Job to Do
Every layer in the Perseus has a specific purpose, and together they give a mattress that feels soft on top and supportive underneath:

• Soft-touch, breathable sleep surface (UK FR knit fabric): The top layer feels gentle against your skin and lets air circulate, which helps keep you comfortable through the night. It also unzips for washing, so the part of the mattress you touch most can be kept fresh and clean.
• Gel memory foam: This layer gives the Perseus its soft, contouring feel. It moulds gently to your body, easing pressure on the shoulders, hips and back, while the gel helps draw heat away for enhanced cooling. That makes it a good choice if you tend to sleep warm.
• High-density foam: This adds extra body support beneath the memory foam. It stops you sinking too deeply and keeps the mattress feeling supportive and consistent over time.
• Isolated pad: Positioned above the springs, it supports the foam-encased pocket springs and keeps them separate from the comfort layers, so the mattress feels smooth on the surface with no spring pressure points.
• Foam-encased pocket springs: This is the core of the mattress. Each spring works independently, responding to your body weight and movement, so you get targeted support and less disturbance if your partner moves in the night. The foam wrapped around the springs helps the edges conform and hold their shape, which gives you a more stable edge and more usable sleeping space across the whole surface.
• Second isolated pad and high-density foam base: These layers sit beneath the springs and give additional support against your bed base. They also stop the springs from pressing through, so the mattress performs consistently for longer.
• Non-slip bottom surface: The base fabric grips your bed frame or divan so the mattress stays put, and it also unzips for washing.

Every layer uses UK fire-retardant (FR) compliant materials, so you know the Perseus meets UK safety standards.

A Generous 26cm Depth
At 26cm deep, the Perseus has the height and presence of a premium mattress. That depth leaves room for all seven layers to do their job properly, so you get thick, cushioned comfort on top and a deep, supportive core beneath. It also gives your bed a luxurious, hotel-style look.

Medium-Soft Comfort, Properly Supported
The Perseus suits sleepers who want a softer, more cushioned feel. It's an especially good match for side sleepers, who benefit from the gentle give around the shoulders and hips, and for anyone who finds firmer mattresses too hard. The pocket springs and high-density foam beneath still give your spine the support it needs, so you wake up feeling rested rather than sunk into the mattress.
