Selecting a mattress goes beyond just pinpointing the right level of firmness. It’s a blend of understanding your body’s unique needs and recognizing what a specific mattress can potentially do for your sleep. To make the process easier, we tested hundreds of firm mattresses and gathered qualitative and quantitative insights that can make your decision easier. give you a full breakdown of how its customers rated it for key factors, including customer service, value for money and incentives

If you loved the Lunarglide series, the Structure 23 also has shades of the Lunarglide (8 & 9) although the Structure 23 is much more cushioned and has a lot more outsole rubber. It does however shine on recovery or long runs at relaxed speeds. Slow runs from 15km up to marathon distances are in its wheelhouse. A cover made from a quilted cotton-microfiber blend encases the entire mattress. This material is fairly breathable, and air circulates freely through the coil layer, so we detected minimal heat buildup during our temperature control tests. If you are an exceptionally hot sleeper, we recommend upgrading the mattress with a phase change panel sewn into both surfaces. Our testers noticed cooling bursts from these panels, which reduced heat buildup and kept the mattress at a comfortable temperature. I love my Structure 23’s for long weekend runs. It serves the same purpose as my Triumph 18’s and my Floatride Run 2.0’s. It’s not nearly as responsive but it beats both of them when it comes to outsole durability. So if the Structure 23 is so different to the Structure 22, why did Nike not just give it a new name? Doesn’t the Structure name conjure images of a firm and stiff ride?

Nike Air Zoom Structure 23 First Impressions

Behind in the boot, the extra 3.5 inches in wheelbase length that this Chrysler enjoys in excess of its Fiat 500 donor design makes all the difference, luggage capacity rising from the 185-litres you'd get in the Fiat to a much more useful 245-litres, though that is still 40-50-litres less than you'd get in a Fiesta or a Corsa. As usual, you can push forward a set of split-folding rear seats (divided 50/50 in the base model but 60/40 otherwise) if that's not enough. I found the level of cushioning to be higher than most daily trainers and even softer than a lot of max-cushioned shoes. It was for sure softer than the Glycerin 18 and the Bondi 7.

However, as Plusnet offers rolling 30 day Sim-only contracts, customers can avoid costly inflation-based mid-contract price increases.This is no more of a stability shoe than the Pegasus, or the Vomero is. The only thing that it shares in common with previous Structures is the name. Previous versions felt as stiff and hard as a plank of wood but the 23 is actually fun to run in even though it is less versatile. Responsiveness is good in the forefoot because of the Zoom Air unit but is less responsive in the soft heel. There is a shallow cavity under the heel which adds a bit more responsiveness. The densities of the lateral and the medial sides are the same but the wall of the medial side is just much higher. Inward rolling of the foot is controlled by making the medial side more cushioned than the lateral side.
