Silentnight sells the UltraGel Cool to Touch 3000 Mirapocket Firmer Mattress on firm support and a cool surface, and I think the build backs up both. 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. 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
Plan the delivery around the weight. It is a big, heavy mattress and the height is a factor from the start. One owner puts it at 64kg and another said it needed two men to carry it upstairs, which is what 37cm of springs, gel foam and pillow top weighs. Standard delivery is to the front door of your building. Room of choice and taking the old mattress away are both paid extras, so add them if the stairs worry you, and measure the turn on the landing before you order.
Unboxing
This is a traditional arrival, lift the mattress onto the base, line it up, and you are done. The pillow top is gel foam, mini springs and polyester under a micro-quilted cover, so expect a cushioned surface with a firm push from below. Owners like the finish: one called it very well made and well built, while another liked the lighter colour round the edging. 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 by label and by build. The 2000 Mirapocket springs are zoned, with extra support through the centre third, which should keep hips and shoulders level for a back sleeper and stop the midsection dropping for a front sleeper. There is some surface cushioning from the pillow top and UltraGel, but I would not expect you to sink deeply. Owners who chose the firm version are pleased with the support, and several were surprised it was not harder than it is. Side sleepers are the exception. One owner who sleeps on their side and front wrote "I'm finding it uncomfortable on my shoulders", which is what I would expect from firm springs under a shallow pillow top. 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. Owners who run warm are pleased with it, and another owner wrote "Keeps you lovely and cool even through mattress protector". Not everyone agrees. One couple said "it doesn't maintain that cooling effect throughout the night as much as we'd hoped". That fits a cool touch fabric, which is at its coolest on first contact, so I would expect neutral for a pillow top design and not icy. 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 should be well controlled. Couples in the reviews agree. One wrote "I can turn over as many times as I need to without waking my husband", and another couple said they no longer keep waking each other up when they move. 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 I would expect excellent stability and few night time disturbances.
Edge support
The specification lists a reinforced mattress edge, and with that on a build this deep I would expect better edge stability than most pillow tops. 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. It comes in a small double, where a soft edge would cost a couple sleeping space they cannot spare. One owner found the extra height made it easier to sit on and stand up from.
Everyday use
Owners keep coming back to the height. It is 37cm deep, and one couple wrote "we actually had to purchase a lower bed frame to compensate for the depth". It is single sided so rotation is essential. The four side handles help with that, although you will want two people because of the weight and depth, and one owner said it is still hard to move alone. Sheets with deeper pockets and a sturdy base make day to day life easier. Each spring sits in its own fabric pocket, so I would not expect squeaks from the spring unit.
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, and what owners say about the support and the cool surface matches the specification.
