Bedroom in Winter: Humidity, Ventilation and the Distance of Furniture from Cool External Walls

During the heating season, the Federal Office of Public Health (BAG) recommends, as a rule of thumb, 30 to 50 per cent relative indoor humidity, ventilating several times a day with a through-draught and 10 centimetres between furniture and external walls. An overview of the official recommendations on bedroom humidity and on furniture against cool external walls, what the studies say about ventilation, and what is not proven.

Hästens or DUXIANA? Two Swedish Heritage Houses, Two Constructions

Hästens and DUX are both Swedish, both handmade — and constructively different. According to the manufacturer, Hästens works with independently acting pocket springs above a Bonnell base spring layer and fills the layers with horsehair, cotton, wool and flax. According to the manufacturer, DUX works with a continuously wound endless spring system made of Swedish spring steel and lets you change the firmness even after purchase via interchangeable Pascal cassettes. We have not found an independent, comparative test of the two systems — this article therefore names no winner, but instead sets construction, materials, adjustability, warranty and price transparency side by side, with a source given for every statement in the text. And so you know who is writing this: we carry DUXIANA. We do not carry Hästens.

This article orders them by founding year, not by rank, and states for each brand its origin, ownership structure and the programmes it claims to stand for, by its own account. All information comes from the manufacturers' own company websites; the full list of sources with access dates appears at the end.

This overview introduces ten luxury bed brands — six that we do not carry, and four from our own range: Hästens, Vispring, Elite, Schramm, Tréca, Auping, DUXIANA, NUVOSETTE, King Koil and Flou. This article organises them by three factual criteria — origin, founding year and core construction — and deliberately avoids any ranking: no independent comparative tests of these models exist, so a ranking could not be substantiated. Our own commercial interest is stated right in the first section: we carry DUXIANA and also our own brand NUVOSETTE, Flou and King Koil. We do not carry six of the ten brands — and describe them nonetheless as accurately as the manufacturers' own statements allow.

Memory Foam or Innerspring? What's Proven — and What Isn't

No system wins across the board: what actually matters, research sorts by firmness and fit, not by material. The documented difference lies in sleep climate: according to Stiftung Warentest, pocket springs run on the cooler side with good moisture transport, while foam runs warmer and benefits those who feel the cold. For viscoelastic foam, the institute found no laboratory advantages in support, pressure distribution or lying comfort — but it also names foam's proven strengths. Disclosure upfront: our range is innerspring-based — which is why every claim in this article carries its source.

Planning an Outdoor Kitchen in Switzerland: Location, Connections, Materials and Costs

If you're planning an outdoor kitchen, it's best to settle four things before getting a quote: location, connections, materials and budget. The best spot sits close to the living area on a solid surface and is oriented so the wind carries smoke away from the seating area – with at least one metre of clearance between the grill and anything flammable, as recommended by the Swiss fire-prevention advisory body. Power belongs at the location as a weatherproof outdoor socket, water either fixed or via a tank, gas via a cylinder or a fixed connection from a specialist installer. List prices from the Swiss manufacturer azado range from CHF 11'900 to CHF 57'800 (as of August 2026) – and whether a building permit is needed depends on the design and is clarified by your municipality.

Bed Linen Materials Compared: Cotton, Percale, Sateen, Linen and Silk

Percale, Renforcé and sateen aren't materials, they're weaves – usually made of cotton; sateen bedding is therefore usually not silk. The fibres differ above all in how they handle moisture: cotton absorbs up to 65 percent of its own weight in moisture without dripping, according to Planet Wissen, silk around a third, and linen is the most permeable to water vapour. When it comes to care, cotton is the most forgiving – Renforcé is usually washed at 40 to 60 degrees, while for silk the care label is what counts. And OEKO-TEX Standard 100 tests for over 1000 harmful substances but says nothing about quality or sleep comfort.

Does a Box Spring Bed Need a Topper?

No – a topper isn't a must: according to Stiftung Warentest (a German consumer-testing institute), good lying properties and comfortable sleep on a box spring bed are possible with or without a topper. A topper can soften a too-firm sleeping surface and add lying height; but it can also mean that the shoulder and hip zones of the mattress lose their effect, and it slows moisture wicking – ÖKO-TEST, another German testing institute, calls buying one "always just a compromise". We show what a topper can really do, where it gets in the way, and how DUXIANA solves the top layer as a replaceable component. Many people end up not needing one at all – and that's perfectly fine.

Calculating Dining Table Size: How Much Table 4, 6 or 8 People Need

Furniture retailers calculate 60 to 70 cm of width and around 40 cm of depth per person – from that come the common guideline sizes: 120×80 cm for four, 180×90 cm for six and 200×100 cm for eight people; round tables need 110 to 125 cm in diameter for six people. Add to that the clearance space: 80 to 100 cm between the table edge and the wall, so chairs can be pushed back. Anyone who knows these figures can check the table size against the floor plan before buying instead of guessing in the shop.

Overwintering Garden Furniture: What Can Stay Outside – and What Can't

Whether garden furniture can spend the winter outside depends on the material, not the calendar: teak, aluminium, stainless steel and high-quality synthetic-fibre weave tolerate the winter outdoors – cushions and pillows, by contrast, belong fully dry and ventilated indoors. Teak greying is, according to the manufacturer, purely cosmetic and doesn't harm the wood. The real opponent is water: when it freezes, it expands by around 9 percent, according to the US Geological Survey (USGS). If you let water drain away, don't pull protective covers all the way to the ground, and store cushions dry, you've taken care of the essentials.

Which Mattress for Side Sleepers? What the Evidence Shows

Side sleeping is the most common sleeping position: an accelerometer study of 664 adults measured an average of 54 percent of sleep time spent on the side. The right mattress for that lets the shoulder and hip sink in under control and supports the waist, so the spine stays straight when viewed from behind. The evidence also points to a mattress perceived as medium-firm and individually adjustable – though "medium-firm" is a subjective rating, and only trying the mattress in side-lying position shows what suits your body. And because how deep the shoulder sinks in also determines the right pillow height, mattress and pillow belong in one shared decision.

Recognising Hand-Blown Crystal Glass: The Four Marks of Craftsmanship

Hand-blown glass reveals itself through four marks: tiny air bubbles – glassmakers call them "seeds" – fine striations, slight variance in shape and size, and the pontil mark on the base where the punty iron was snapped off. In museum documentation, these features count as marks of manual production; one long-established glassworks calls them simply "proof of authenticity". On the term "crystal", EU directive 69/493/EEC helps: lead-free glass may also be called crystal glass if it contains at least 10 percent of certain metal oxides and meets density and refractive-index requirements. Knowing these features lets you judge instead of guess.

How High Should a Nightstand Be – and Which One Suits Your Bed?

The top of the nightstand belongs roughly at the height of the top of the mattress – that's the rule of thumb that runs through practically every retail guide. It isn't a standard: depending on the source, it says "level with", "slightly above" or, occasionally, "slightly below" – a centimetre or two either way doesn't matter. As common market guideline figures: around 30–45 cm for a low bed, 45–55 cm for a classic frame, 55–70 cm for a box spring bed. We also clarify when a wall-mounted nightstand is the better choice and which light belongs on the surface.

Pendant Light Over the Dining Table: Getting Height, Size and Number Right

About 60 centimetres between the tabletop and the bottom edge of the fixture – that's the proven hanging height for a pendant light over the dining table; manufacturers cite up to 75 or 80 centimetres depending on the model. For size, two rules apply that are often confused: round fixtures measure at most half the table's width, linear fixtures around two-thirds of the table's length. From about 180 centimetres of table length, manufacturers recommend two pendants, and warm-white, dimmable light around 2700 Kelvin has become the established colour temperature. There's no standard for the private dining table – we show where each rule of thumb comes from.

Is a Sofa Bed Suitable for Sleeping on Every Night?

Yes, a sofa bed can work for sleeping on every night – but only if it's built for it: with a proper slatted base, a separate mattress and adequate dimensions. As a guideline, specialist retail guides cite a lying height from around 40 cm, a lying width from 140 cm for couples, and a mattress thickness around 14 cm – rules of thumb, not standards. For occasional guests, a fold-out sofa with a foldable foam mattress is enough; there, foam is even the right construction choice, because springs would bend when folded. We map out where the line lies between a guest solution and a permanent sleeping place – and when a proper bed is the more honest answer.

How to Determine Rug Size: Rules of Thumb for the Living Room, Dining Room and Bedroom

There's no standard for rug sizes – but rules of thumb that large furniture and rug retailers largely agree on. In the living room, the rug should be roughly 40 to 60 cm wider than the sofa; in the dining room, it needs 60 to 80 cm of extra room per side of the table for chairs to be pulled out; in the bedroom, 20 to 50 cm of visible overhang around the bed is enough. Anyone who knows these three ranges can work out any rug size themselves within minutes. This guide walks through the rules room by room – with worked examples from a table for four to a table for eight.

We carry all three approaches – slatted frame with innerspring mattress (Flou), box-spring and multi-layer spring systems (DUXIANA) – and therefore compare without any vested interest in a particular answer.
