The Hyde & Sleep Ruby Lite Rolled Memory Foam Mattress is a firm, no-nonsense memory foam option that leans into support over indulgent softness. In store, it comes across as a solid, practical mattress with a clear aim, keep the body level and reduce pressure through contouring foam, without the deep sink that softer memory foam beds can bring. The rolled delivery and 100 Night Comfort Guarantee add convenience and reassurance, but the real selling point is the promise of targeted zoned support paired with a straightforward, supportive feel.
Construction & materials
This mattress is built around contouring memory foam combined with three layers of support, with zoned support designed to cushion and prop up different parts of the body more precisely. The memory foam element is there to adapt to body shape, while the underlying support layers stop it from feeling like a slow, collapsing foam slab. The overall impression is of a mattress engineered to keep alignment tight, rather than one trying to create a plush hotel-style surface.
Comfort, firmness & feel
Despite the memory foam on top, the Ruby Lite feels firmly set and supportive. It gives enough at the surface to take the edge off pressure points, but it does not offer that deep, enveloping hug some people expect from memory foam. Instead, it keeps sleepers more "on top" of the mattress than "in" it. That firmness can feel reassuring and stable, but it is also the feature most likely to divide opinion, especially for those used to a softer top layer.
Support & pressure relief
The zoning and memory foam combination is geared towards keeping the spine aligned while still smoothing out pressure at contact points. Customer feedback backs up that the contouring and zoned support noticeably improve comfort and sleep quality, with pressure relief landing where it is needed most. In practice, the mattress feels structured rather than forgiving, which is excellent for maintaining posture but less ideal for people who need extra give through the hips and shoulders.
Motion isolation
The all-foam style and memory foam contouring typically work in favour of motion control, and the Ruby Lite presents as a steadier, less reactive surface than many spring-based mattresses. It feels like it would do a respectable job of muting movement, particularly compared with bouncier designs, although the firmer feel means it is not the most "dead" surface going.
Temperature regulation
There is not enough detail provided about cooling features or breathable components to make firm claims here. What can be said is that the feel is more supportive and less sinky than many softer foam mattresses, which can help reduce that wrapped-up sensation some people associate with warmer sleep.
Edge support
Edge support is not specified. In store, the Ruby Lite presents more as a mattress focused on central alignment and pressure management than one making a big play for reinforced edges, so anyone who routinely perches on the side of the bed may want to pay attention to how it feels right at the perimeter.
Practicalities
- Rolled delivery: Arrives rolled, making it far easier to get through tight hallways, staircases and smaller rooms, and generally simpler to set up.
- 100 Night Comfort Guarantee: Adds peace of mind, particularly useful with a firmer mattress where comfort can be more polarising.
Who it suits
This is best matched to back sleepers who want a firm, steady surface that prioritises alignment, and to some stomach sleepers who benefit from a mattress that stops the pelvis dipping too far. It is also a strong choice for anyone who finds softer memory foam too yielding and would rather have light contouring on top of a supportive base.
Who it does not suit
Side sleepers, particularly those with more pronounced curves or anyone who tends to load pressure into the hip and shoulder, are likely to find this too firm. The surface does not offer the kind of deeper sink at the sides that many side sleepers need to stay comfortable and properly aligned, which can lead to pressure build-up and restless sleep.
What customers liked
Feedback highlights the way the memory foam and zoned support work together, with noticeable improvements in comfort and sleep quality. The contouring feel is repeatedly framed as pressure-relieving without losing support, and the layered build is appreciated for keeping the body aligned through the night rather than letting it sag.
Final verdict
The Hyde & Sleep Ruby Lite is a firm memory foam mattress that delivers on its "support first" brief. It is not a plush, sink-in crowd pleaser, but it is convincingly stabilising and feels purpose-built for sleepers who want their mattress to hold them level. For back sleepers wanting a straightforward, supportive foam feel with targeted zoning, it is a strong option. For side sleepers chasing cushioning and easy pressure relief at the shoulder and hip, the firmness is a deal-breaker rather than a benefit.
