The Silentnight SleepResponse Reflex 1600 Combination Mattress is a Dreams-exclusive model built around the brand's Mirapocket spring system and a cooling gel comfort layer. On paper, it targets people who like a softer, more adaptive feel, particularly anyone who changes position through the night and wants a cooler surface than traditional memory foam tends to offer. A 100 Night Comfort Guarantee adds a useful layer of reassurance for a mattress that is hard to judge without sleeping on it.
Construction and materials
This is a sprung mattress with multiple spring types and a gel comfort layer, rather than an all-foam design. Silentnight positions the gel as a more breathable alternative to standard memory foam, paired with a specialist cover intended to pull heat away from the body.

- Adaptive micro springs, designed to respond to smaller movements
- Premium cooling gel filling for pressure-sensitive comfort
- Cover woven with CoolEase technology to draw heat away and reduce overheating
- Single-sided design for easier care
- Includes recycled materials
- Made in the UK
- 100 Night Comfort Guarantee and a 5-year guarantee are provided
Comfort, firmness and feel
The stated comfort is soft to medium, which usually translates to noticeable cushioning at the surface with less of that rigid, push-back feel some pocket-sprung mattresses can have. The gel layer is described as responsive to movement, so the feel is likely to be more adaptive than slow-moulding, traditional memory foam, although the exact sensation is not confirmed beyond the provided description.
Support and pressure relief
Support should be more targeted than with open-coil spring systems because the pocket springs are individually wrapped, helping different areas of the body settle without forcing the whole surface to move as one. Customer feedback also highlights zoned support aimed at better spinal alignment. With a soft-medium tension, this model is a better bet for sleepers who benefit from extra give at the shoulders and hips, rather than those who need a very firm, held-up feel.
Motion isolation
Pocket springs typically reduce motion transfer compared with linked springs, and the customer feedback specifically notes reduced motion transfer. The addition of micro springs may help the surface respond in smaller increments, which can also make the top feel less disruptive when a partner moves, although no formal testing data is provided here.
Temperature regulation
Cooling is one of the main selling points. The gel layer is described as five times more breathable than standard memory foam, and the CoolEase cover is designed to pull heat away quickly. Combined with the airflow benefits that sprung cores often bring, this should suit anyone who finds dense foams tend to trap heat, though real-world temperature performance will still depend on bedding and room conditions.
Edge support
Edge support is not described in the supplied specifications or reviews, so it is not possible to confirm how stable it feels when sitting on the side or sleeping right up to the edge.
Practicalities
This is a single-sided mattress, which generally means no flipping, only occasional rotation if recommended by the retailer or brand. That is a genuine day-to-day advantage for heavier mattresses and for anyone who does not want the upkeep of a two-sided design. It is also noted as being made in the UK and containing recycled materials, which may matter to shoppers trying to balance comfort with more responsible materials choices.
Who it suits
- Side sleepers who typically need more pressure relief at shoulders and hips
- People with a lower BMI than average who often find firmer mattresses feel unforgiving
- Those with hourglass figures who benefit from extra sink-in to accommodate hips and shoulders
- Fidgety sleepers who want a surface designed to respond to movement
- Hot sleepers drawn to a cooler-feeling cover and a more breathable gel layer than standard memory foam
Who it does not suit
- Anyone who knows they need a genuinely firm mattress feel
- People who prioritise very strong edge stability, as edge support is not confirmed in the provided information
- Shoppers who specifically want a traditional slow-melting memory foam hug, as this gel layer is described as more breathable and responsive
What customers liked
- A cooler, more comfortable sleep, credited to the CoolEase cover and breathable fibres
- Zoned support for improved spinal alignment
- Reduced motion transfer, which can help couples sleep with fewer disturbances
- The combination of Mirapocket and micro springs for a more responsive support system
What customers disliked
There is not enough customer review detail provided to report meaningful downsides or recurring complaints for this model.
Final verdict
The Silentnight SleepResponse Reflex 1600 Combination Mattress reads as a well-judged choice for sleepers who want soft-medium comfort without committing to a heat-trapping, all-foam build. Its strongest story is the cooling-focused cover and gel layer, backed up by a pocket spring system designed for targeted support and lower motion transfer. It looks particularly well suited to side sleepers and those who benefit from extra contouring, but it is less convincing for anyone who needs a firmer, more perched-on-top feel, or who requires confirmed edge support. The 100 Night Comfort Guarantee makes it a safer purchase if the comfort level is a bit of an unknown.
