If you have already heard of Hypnia, you already know Slome. The French online mattress brand underwent a complete rebranding in 2026: same DNA, same range, same commitments — but a shorter, more international name designed to support its development beyond French borders. This change in identity has caused some confusion among buyers in the research phase, and this is precisely why this article exists: to clear up any ambiguity and give you a clear vision of what Slome offers today, for whom its mattresses are suitable, and how to compare them to the competition.

Hypnia becomes Slome: what changes (and what doesn’t)

In 2026, the brand underwent a complete rebranding to become Slome, with the stated goal of adopting a shorter, more international, and more distinctive identity as it expands beyond France. This is a classic strategic move for a mature online bedding brand, and not a takeover or change of ownership.

Slome is the new name of Hypnia. The brand has undergone rebranding, but the products, materials, certifications, and manufacturing standards remain the same. This point is essential for buyers: the rebranding is cosmetic, not product-related. The catalog is identical. In practice, depending on available stock, your mattress may arrive with the name Hypnia, Slome, or without a logo — nothing changes under the cover.

Slome is a French brand, whose official website is slome.fr , and which currently delivers to France, Belgium, Switzerland, Luxembourg, and Monaco.

Slome’s positioning: value for money above all

Slome is in line with direct-to-consumer (DTC) mattress brands: exclusively online sales, without a physical distribution network, which allows it to maintain competitive prices for products with premium characteristics. The brand’s message is clear: a good mattress does not necessarily have to be an expensive mattress — it is a mattress that suits your sleeping habits and combines the right technological combination, appropriate thickness and foam density with quality materials for lasting comfort.

This positioning allows it to appeal to a wide audience: sleepers who want to access a higher level of comfort than what is offered by large specialized retailers, without having to pay the sums demanded by the most high-end brands on the market.

The Slome mattress range in 2026

Slome offers several models that cover the essential needs: high resilience foam, memory foam, hybrid with pocket springs, and latex. The range is clear and structured, making it easier to choose according to sleep profiles.

Supreme Well-being: the flagship hybrid model

The Slome Supreme Well-being mattress is offered starting at €755 in size 140×190 cm — an attractive price for a high-quality hybrid mattress, with promotions regularly available. With its premium materials and bamboo fiber cover, this model has the characteristics of a true high-end mattress.

It is a hybrid mattress, meaning it combines layers of foam (including memory foam) with pocket springs. This construction allows for the advantages of each technology to be combined: the active support of the springs for varied positions, the adaptation to body shape provided by the foam, and the movement absorption beneficial for couples.

Absolute Well-being: the thick all-foam model

The Absolute Well-being is a 30 cm model made up of 4 layers. It is the all-foam choice of the range, designed for sleepers who prefer a enveloping feel without springs. Its generous thickness places it in the comfort+ segment, ideal for those suffering from back pain or seeking progressive support.

Hybrid mattresses with latex

The combination of different materials such as memory foam, high resilience foam, pocket springs, or latex allows for the strengths of each to be combined. With latex, the mattress benefits from a comfortable, extremely flexible feel and incomparable softness due to its elasticity. This variant is aimed at sleepers sensitive to heat, as latex is naturally more breathable than polyurethane foam.

Trial, warranty, and customer service

One of Slome’s major strengths is its commercial policy, particularly generous for a brand positioned in the mid-range:

  • 120-night trial — or four months — with free return and full refund in case of dissatisfaction. Delivery is also free.
  • The warranty is valid for 10 years and covers all manufacturing defects.

These conditions place Slome among the top DTC brands in France: 120-night trials far exceed the legal standard of 14 days for online purchases, and the ten-year warranty represents a serious commitment to product durability. It is also a strong signal for buyers who are questioning the reliability of an online order without prior in-store testing.

Slome mattress toppers

Beyond mattresses, Slome offers three models of mattress toppers, each providing specific advantages and catering to different sleep profiles. The Essential topper is the entry-level model: 5 cm thick, it consists of two layers, one of which is a cooling memory foam. It is a practical solution for improving an existing mattress without replacing it, or for softening a mattress deemed too firm.

Who is a Slome mattress for?

Slome primarily targets the following profiles:

Buyers looking for value for money. The brand has built its positioning on the idea that a good mattress does not necessarily have to cost more than €1,000. Sleepers who carefully compare technical characteristics against price will find an offer here that is hard to ignore.

Couples with different body types. The hybrid models, with their independent pocket springs, limit the transmission of movement from one side of the bed to the other. This is a concrete argument for partners with differing sleep rhythms.

Sleepers who get hot at night. The versions with latex or bamboo fiber covers offer better air circulation than all-synthetic foam models. If you tend to sweat at night, these options deserve your attention.

Cautious buyers who want to test before committing. With 120 nights of trial and free returns, the risk is almost zero. This is a strong argument for those hesitant to buy a mattress without trying it in-store.

On the other hand, if you want to physically test a mattress before purchase, Slome — like most DTC brands — does not have a network of showrooms in France. Everything is done online, which means relying on descriptions and reviews to refine your choice.

Customer reviews and online reputation

Customers generally consider Slome to be a reliable brand, particularly mentioning the quality of materials, durability, and prices as its best assets. The transition from Hypnia has gone smoothly for existing customers, indicating a continuity of careful service.

On the less positive side, criticisms generally focus on delivery times during peak demand periods and a break-in period that may sometimes be necessary for memory foam mattresses — which is common across all brands in the category. Nothing that undermines the intrinsic quality of the products.

How does Slome compare to the competition?

In the French online mattress market, Slome positions itself between entry-level brands (often under €400) and premium players like Emma or Tediber, whose flagship models can exceed €1,000 for a double. Its main strength is offering well-constructed hybrid mattresses at accessible prices, without cutting back on the trial period or warranty duration.

Is Slome really the same as Hypnia?

Yes, Slome is indeed the new commercial name of Hypnia. The rebranding took place in 2026, with the goal of adopting a shorter identity more suited for international expansion. In practice, the products, materials, certifications, and sales conditions (trial, warranty, delivery) are strictly identical to what they were under the Hypnia name. Only the logo and name have changed. If you received a delivery made during the transition period, your mattress may have arrived branded Hypnia, Slome, or without a logo — this does not change what is under the cover. For former Hypnia customers, after-sales service and warranty remain assured normally under the new Slome brand.

What is the trial period offered by Slome?

Slome offers a 120-night trial, or about four months. This is one of the longest periods in the French online mattress market, and it far exceeds the legal withdrawal period of 14 days applicable to online purchases. During this period, if the mattress does not suit you, you can return it for free and receive a full refund. This policy is particularly interesting for buyers who want to take the time to evaluate their mattress over time, especially for issues related to back pain that often require several weeks of adjustment before stabilizing.

What warranty do Slome mattresses have?

Slome mattresses come with a 10-year warranty covering manufacturing defects. This is a solid standard in the category of French DTC brands, comparable to what well-established players in the sector offer. In practice, this warranty covers structural issues (abnormal sagging, sewing defects, premature material deterioration) but not normal wear and tear from daily use. To maximize the lifespan of your mattress, it is recommended to rotate it regularly (two to four times a year) and use a suitable base — slatted with reasonable spacing, or a box spring depending on the model.

Does Slome deliver to Belgium, Switzerland, and Luxembourg?

Yes. Slome is active in several French-speaking markets: France, Belgium, Switzerland, Luxembourg, and Monaco. The official site slome.fr handles orders for all these markets. Delivery conditions (timelines, potential fees) may vary from country to country, especially for Switzerland due to customs specifics. It is advisable to check the terms directly on the site at the time of order, as conditions may evolve.

Are Slome mattresses suitable for people with back pain?

An appropriate mattress can indeed help improve comfort for those suffering from back pain, but the answer largely depends on the type of pain and body shape. For lower back pain, a mattress that properly supports the spine in alignment — neither too firm nor too soft — is generally recommended. Slome’s hybrid models, with their combination of pocket springs and foam, offer a good balance between support and body adaptation. The memory foam, present in several references, reduces pressure points, which can relieve pain in the shoulders and hips. In any case, the 120-night trial allows for real testing of the mattress in your usual sleeping conditions before making a final commitment — this is the best way to assess a mattress’s compatibility with your body shape and any potential pain.
