Buying guides

Here you'll find all the "Best…" guides from the Looniva blog, divided by product and by need. Each guide ranks the fabrics you actually find in shops, with a score from 1 to 10, the criteria and the weights written out clearly. Looniva is our brand and comes first in every ranking: that's why we also show you the sum.

Looniva is our brand: these rankings are our judgement, with the criteria and the weights written out in every guide. Updated on 26 October 2026, by Edoardo Guarise.

By product

  • Best double duvet covers: six fabrics compared, the right size for your duvet and what a rotation of two costs.
  • Best double bed sets: what's in a set, when it makes sense compared with buying the pieces one by one, how many sets you need.

By need

The next guides in the series (sheets, pillowcases, single beds, for those who sleep hot) will be added to this list the day they come out. If you already know what you need, all the bamboo viscose bedding is in the Looniva catalogue.

How we give scores

Each fabric gets a score from 1 to 10 on four, five or six criteria. Each criterion has a percentage weight, and the weights add up to 100. The final score is the sum of the scores multiplied by their weight.

The criteria change from guide to guide, because the question changes. On the duvet cover, touch comfort weighs most (25%), because it's the fabric you have against you all night. On pillowcases for people with acne, the smooth surface and how easy they are to change often weigh most (25% each). On bed sets, completeness of the set and price weigh most (25% each). Every guide has a table of criteria with the weights, before any recommendation.

An example with numbers, from the Looniva duvet cover: comfort 10 at 25%, humidity 9 at 20%, size and closure 9 at 20%, care 8 at 15%, price 7 at 20%. That makes 2.5 + 1.8 + 1.8 + 1.2 + 1.4, i.e. 8.7. If your weights are different, redo the sum with yours: someone who washes everything at 60 °C will give more weight to care, and the winner changes.

The rules we follow in every ranking
Rule What it means in practice
We compare fabrics, not brands percale, cotton satin, linen, microfibre, flannel, silk: no other brands
Every line has a limit including Looniva: bamboo viscose must be washed at 30 °C and not put in the tumble dryer
Looniva's sum is written out score by score, with the criterion where it scores lowest
Prices with source and date prices for other fabrics only if we have collected them from a public page, with the day; otherwise n/a
Looniva prices from the shop read on the day the guide comes out

We don't like n/a in the table much, but we use it anyway: an empty box tells the truth, an invented price range does not.

What the scores don't measure

The scores show how well a fabric meets the criteria of that guide. They don't tell you whether it's right for your bed, which has its own sizes, or for your washing habits.

The scores don't measure health. When a guide talks about a need that concerns skin or body, we write what the fabric does. Viscose is an artificial fibre made from cellulose (Treccani, viscose): it's smooth, it can be washed often, it holds about 13% moisture according to ASTM D1909. Then we write the practical routine. For skin and health, the reference remains the dermatologist or doctor.

The scores don't measure how many years something lasts. We have no laboratory evidence on how fabrics hold up over time, and we don't write numbers we can't show.

Frequently asked questions

Why is Looniva always first?

Because we write the guides ourselves and put our fabric where we think it belongs. That's why each guide shows the weights and the sum of our score, and says who should choose something else: you can redo the calculation with your priorities and reach a different answer.

How often do you update the guides?

When the prices or sizes in our catalogue change, and when we find a new source for the prices of other fabrics. The date of the series' last update is at the top of this page.

What certification does the bamboo fabric have?

The fabric is certified OEKO-TEX Standard 100 class I, the class with the strictest limits on harmful substances. The certification applies to the fabric, and you'll find it mentioned in every guide where it matters.

Can I return a product if I'm not happy with it?

Yes, returns are possible within 30 days for unused items. Shipping within Italy costs €5.90 and is free over €109.
