Why our sleep experts loved it
I slept on the Silentnight UltraGel Cool to Touch 3000 Mirapocket Firmer Mattress for a few nights to see if its firm support and cool surface really do add up to better sleep. On paper it is a deep, single sided pillow top with a lot going on inside: 2000 Mirapocket springs for support, 1000 mini springs for extra response, an UltraGel layer, and a cool touch fabric. After weeks of use I can say it is a well-structured, supportive mattress that is temperature regulating for a gel model, with a few compromises you should be aware of before buying.
Delivery
Delivery was direct to the room. No rolling, no decompressing, no chemical whiff when the wrapping came off. It is a big, heavy mattress and the height is a factor from the start. The cover looked clean and taut, the quilting was even, and the handles were well stitched. The crew took away all packaging. It was sleep ready that night.
Unboxing
This is a traditional arrival, lift the mattress onto the base, line it up, and you are done. The pillow top is plush without being fluffy. The top fabric has that cool first touch feel you notice when your hand lands on it. The side panel is tidy and the tape edges are straight. No ripples, no baggy fabric, just a neat finish. Because it is deep, fitted sheets with a deeper pocket work best.
Construction
The support core is 2000 Mirapocket springs. Each is in its own fabric pocket so it can move independently under your weight and keep the surface stable. On top of that are 1000 smaller mini pocket springs that add extra response under the pillow top. Sandwiched into the comfort stack is an UltraGel layer. This gel infused foam adds pressure relief and a little bounce, and the open cell structure is there to help air move through the top of the mattress. The finish is a single sided pillow top, so all the comfort is on the sleeping face and you rotate rather than flip. The tension is marked firm so naturally suits back sleepers while the spec includes turning handles, and the guarantee is five years. The overall depth is substantial, in the mid to high 30s in centimetres depending on retailer measurement, which explains the weight and the visual heft on the bed.
Comfort
This is a firm mattress and it feels like one. Lying on my back, my hips and shoulders stayed level and my lower back felt supported without a hollow. There is some surface cushioning from the pillow top and UltraGel, but you never sink deeply. On my side, the mini springs and gel layer soften the first contact so the shoulder does not feel slammed into a hard surface, though you still feel a firm pushback underneath. Front sleeping is very stable. The midsection stays up and the spine feels flat. If you need a lifted, on top feel with a bit of give on the surface, this is exactly that. If you want a deep, slow contour, this is not the one.
Temperature regulation
Gel foams can run warm in some mattresses. Here the cool to touch fabric gives an immediate fresh feel at the surface and the open cell UltraGel helps avoid that sticky heat build up. The pocket springs allow air to move beneath the comfort layers. I slept comfortably in a warm room without the clammy sensation you sometimes get from dense foams. It is not icy, but it is consistently neutral for a pillow top design. Bedding choice still matters. A breathable protector keeps the surface feel and airflow working as intended.
Motion transfer
With 2000 Mirapocket springs doing the main support and 1000 minis in the comfort stack, motion is well controlled. When my partner turned I felt a soft nudge rather than a roll. The pillow top and gel layer absorb the start and end of movements so they do not ripple across the whole bed. It is not rigid like an extra firm orthopaedic slab, but for a plush topped mattress the stability is excellent and night time disturbances are low.
Edge support
Edge stability is better than most pillow tops. Sitting to tie shoes does not collapse the border and sleeping close to the side feels secure. The deep build and the spring layout help the perimeter hold its line. That extra usable width matters when two people share a smaller size. Over the review period the edges did not soften or slope.
Everyday use
After a settling week the surface feel became consistent night to night. The pillow top stayed level without ridges and the quilting kept its shape. It is single sided so rotation is essential. I rotated it monthly and the handles made that manageable, although you will want two people because of the weight and depth. Sheets with deeper pockets and a sturdy base make day to day life easier. Noise is a non issue. No squeaks from the spring unit, no creak from the edge, just a quiet, planted feel.
Who this suits
Back and front sleepers who want firm support with a hint of surface comfort will get on well here. Hot sleepers who usually avoid foam will be happier with the cool touch fabric and the open cell gel than they expect. Couples who need motion control will appreciate the stability of the dual spring layout. If you like a deep, hotel style bed that feels structured and substantial, this hits that brief.
Who it does not suit
Dedicated side sleepers who need deep pressure relief at the shoulder may want more softness than this offers. If you like to sink in and feel hugged, the pillow top here will feel too shallow. Anyone who cannot easily rotate a heavy mattress should consider the weight. And if you want a two sided, flip and turn build for maximum longevity in the top layers, this is not that design.
Care and maintenance
Use a breathable protector from night one to preserve the cool touch feel and keep the surface clean. Rotate head to toe every month for the first three months, then every two to three months. Always lift with the handles and do it with two people. Air the bed in the morning for a few minutes before dressing it so moisture from the night can escape. A strong base and deep pocket sheets make ownership simpler.
Verdict
The Silentnight UltraGel Cool to Touch 3000 Mirapocket Firmer Mattress is a well executed firm pillow top with real day to day advantages. It keeps you feeling uplifted and aligned, it stays temperature neutral for a gel model, and it mutes partner movement without feeling dead or dull. The trade offs are the expected ones. It is heavy, it is single sided, and side sleepers who want deep sink will wish for more give. If you want a deep, supportive mattress with a calm surface that feels cool on contact and steady underneath, this is a strong choice that behaves exactly as promised.
