The Silentnight SleepResponse Breatheasy 1400 Pocket Sprung Mattress is a Dreams-exclusive that leans hard into two promises, firmer orthopaedic-style support and a cooler, fresher sleep. In store, it comes across as a proper no-nonsense mattress, built for people who want their bed to hold them up rather than hug them. The overall feel is very firm and controlled, with a springy, responsive character rather than a slow-sinking foam sensation.
Construction and materials
This mattress uses responsive pocket springs, individually wrapped to move more independently than traditional open coils. Silentnight brands these as Mirapocket springs, with 1,400 springs and targeted zoned support to help keep the spine better aligned. It also uses eco-friendly recycled fillings, paired with breathable fibres designed to improve airflow. The sleep surface is quilted and aloe vera-infused, which is positioned as a skin-soothing touch rather than a core performance feature.
Comfort, firmness and feel
The comfort rating is very firm, and it delivers exactly that. On test, the surface feels taut and supportive, with minimal initial sink. The quilted top takes a little of the edge off, but this is not a plush mattress, it is built to feel stable and straight. Anyone expecting a cushioned, cloud-like top layer will find it unforgiving, but sleepers who like a flatter, firmer platform will immediately understand the appeal.
Support and pressure relief
Support is the headline strength here. The pocket springs give the mattress a more adaptive feel than an old-school orthopaedic mattress, and the zoned support helps keep the midsection from dipping out of alignment. Pressure relief is present, but it is delivered in a firm, functional way rather than through deep contouring. It is the sort of mattress that prioritises posture and even weight distribution over softness.
Motion isolation
With individually wrapped springs and a design that aims to reduce motion transfer, movement is better contained than on a basic spring mattress. In practical terms, it stays reasonably composed when weight shifts, although the overall firmness and spring response mean it will never feel as motion-deadening as a thick memory foam model.
Temperature regulation
This is clearly pitched at warm sleepers, and the materials do support that story. Breathable fibres and airflow-focused design elements are intended to keep the sleep environment fresher, and the spring-based core naturally allows more ventilation than dense foam. In store, it feels like a mattress that will sleep on the cooler side of average, particularly compared with more enveloping foam options.
Edge support
The strong, firm build helps the edges feel usable, especially for sitting to put on socks or sleeping closer to the perimeter. It holds its shape well under load, although the exact edge construction is not detailed beyond the spring and filling approach.
Practicalities
It comes with a 100 Night Comfort Guarantee, which takes some pressure off committing to a very firm tension. The mattress is single-sided, so maintenance is rotation-only rather than flipping, which is a genuine day-to-day convenience. It is backed by a 5-year guarantee.
Who it suits
This mattress suits back sleepers who want a firm, straight sleeping surface and prefer to feel supported on top of the bed rather than settled into it. It also works well for some stomach sleepers, where that extra firmness can help keep hips from sinking too far and pulling the lower back out of position. Warm sleepers who dislike heat build-up in plusher, more insulating mattresses should also find the breathable, spring-led design a sensible match.
Who it does not suit
It is a poor fit for most side sleepers, particularly those with hourglass figures or anyone who needs more sink at the shoulder and hip to stay comfortable and aligned. The very firm tension does not readily give way in those pressure points, so it can feel more like pushing back than cushioning. It is also not the one for people who want a soft, snuggly top layer or that classic memory foam hug.
What customers liked
Feedback highlights the combination of comfort and support, with particular praise for the zoned spinal alignment and the reduced motion transfer from the pocket spring design. The breathable fibres and mesh border get credit for helping the mattress feel cooler and fresher. The eco-conscious angle, using recycled materials, is also seen as a meaningful positive rather than empty marketing.
What customers disliked
There is not enough negative feedback provided to draw a fair pattern of complaints.
Final verdict
The Silentnight SleepResponse Breatheasy 1400 is a confident, very firm pocket sprung mattress that does its best work for back sleepers who want clear structure and cooler, more breathable night-time comfort. It is not a crowd-pleaser, the tension is unapologetically firm, and that will rule it out for many side sleepers. For the right buyer, though, it feels like a purposeful, well-judged mattress with strong support credentials, sensible rotation-only upkeep, and a reassuring 100-night comfort guarantee to back up the decision.
