Introducing The Karpen Sidestich Collection
All Aireloom beds advertise their ability to conform to your body, provide proper body balance and support, and optimize pressure relief and luxury. Each mattress is built with natural fibers, high-quality damask fabrics, and Viscoelastic foam aimed to maximize comfort, durability, and support. This Karpen Sidestich Collection is one of five collections Aireloom offers. Inside this collection is four beds — three Rip Van Winkle mattresses and one super featherbed — with a design and construction that seems pretty labor intensive. The Karpen Sidestich mattresses are handmade with an impressive 42 pounds of cotton in its comfort layer and sealed with 560 heritage side-stitches (where the “sidestich” collection gets its name) and uses exclusive coil design to provide responsive support. The “Karpen” comes from King Karpen, who founded the company back in 1940. Now let’s look at the four different beds in the Sidestich collection. The first three are different firmness levels of the “Rip Van Winkle” series, which come in medium firm, luxury firm, and extra-firm comfort levels. We’ll look into these three first. Afterward, we’ll dive into the Karpen Sidestich Super Featherbed mattress, which provides a unique plushness aimed for people who love soft beds.Aireloom Karpen Materials: A Breakdown
Before we explain what’s inside each mattress, we thought it would be helpful to include a glossary of sorts that explains what all of these materials mean, especially since some have been trademarked by Aireloom. Here are some names that will pop up in this article that you need to know: Tencel® Fabric: A sustainable fabric regenerated from wood cellulose. It is soft and flexible and provides cooling support. Pillowflex™: A unique quilting foam that Aireloom claims is more resilient than other similar materials and is used as an alternative to traditional quilting foams. Aireloom Lift™ An air chamber between the springs and mattress top that increases the areas of low pressure when you’re laying on the mattress to give off the feeling of being cradled. Silk/Wool Fibers: Naturally breathable fibers that help regulate body temperature while you sleep. Talalay Latex: Made out of natural material, this latex foam helps the body maintain a consistent body temperature throughout the night. Support-flex™ Coils System: Individually wrapped coils which allow each coil to react independently from each other, providing more specific support and improving motion control.Rip Van Winkle Beds: Construction
Now, let’s dive into what these mattresses are made from.
Quilt/Cover
The Rip Van Winkle Medium Firm, Luxury Firm, and Extra firm mattresses all have a stretch knit cover fabric made from a blend of Tencel (a cellulosic fiber obtained from wood pulp that promotes coolness) and Polyester (which creates durability and smoothness). The fabric for the mattress cover is made of silk and wool fibers with an added layer of firm, high-density foam — the thickness amount is what various among the three models. Moreover, for the Rip Van Winkle Medium Firm and Luxury firm models, there is a layer of Aireloom’s PillowFlex foam to add a hint of softness to the cover.Comfort Layer
As for the comfort layer, each bed uses a ventilated Talalay latex with various thickness depending on the model. As you can imagine, the medium-firm model will have the thickest layer of comfort foam, while the extra-firm model will have the thinnest. The comfort section of all mattresses has a base layer of an extra-firm high-density foam called Energex™. All three Riv Van Winkle mattresses also have an inner-tufted comfort layer made of 54 hand-tied tufts, 42 pounds of cotton felt, and a meticulous hand-stitched border. There is added edge support made from high-density foam.Foundation and Support
All three Rip Van Winkle beds are innerspring mattresses with the same foundation and support system. Their innerspring units use offset coils; the 13-gauge steel wire in these springs are double-tempered with six active turns. The box spring foundation for each mattress is hand-tied 8-ways with modular coils and come in 9-inch or 5-inch profiles.
Karpen Sidestich Super Featherbed: Construction
The other mattress in this collection is the Karpen Sidestich Super Featherbed. This mattress includes another complex layer: a featherbed plush pillow top. These beds will come in at 15.25 inches thick. Let’s break down what’s inside:Quilt/Cover
The quilt itself is made with an organic cotton stretch knit fabric and includes silk and wool fibers, high-density plush foam, and True-stretch™ cotton tricot.Comfort Layer
The comfort layer on this bed also has ventilated Talalay latex with Visco elastic memory foam. There is an inner-tufted comfort layer made of 54 hand-tied tufts and 42 pounds of cotton felt, which is finished off with the hand-stitched border and a high density foamed edge.Foundation and Support
The super featherbed mattress uses 13 gauge double knotted offset coil units surrounded by edge support in the form of a high-density foam.Aireloom Karpen Sidestich Mattress Feel
All four beds are going to have different firmness levels due to the differences in comfort foam layers. Luckily their names help to easily identify comfort and feel. The Rip Van Winkle Extra Firm bed will obviously be the most firm, followed by the Rip Van Winkle Luxury Firm, Rip Van Winkle Medium Firm, and then the Super Featherbed. This sidestich series differs from the Karpen Luxury Line due to its emphasis of natural cotton and the side-stitch design. It’s worth mentioning (again!) that this collection is made with over 40 pounds of organic cotton, which is known to be far softer than conventional cotton and also stronger and more durable. The labor-intensive side stitches (560 per mattress!) provides an extra feeling of durability and support, especially on the edge of the bed. Another thing to note: Motion control tends to be tamed with these mattresses. This is due to the use of double knotted offset coils. Rather than the ends of the coils remaining loose, the ends on these mattresses are looped around and double knotted, creating an hourglass shape. This feature, along with the heavy gauge wire used, makes this coil structure resilient and strong, preventing motion transfer and providing ample durability. Lastly, the Patented Aireloom Lift™ we mentioned earlier in the “glossary” is important to mention again. The ‘Aireloom lift’ aims to provide a feeling of weightless and of being cradled.
Aireloom Karpen Luxury Vs. Others
You might be wondering how the Aireloom Karpen Sidestich mattresses compare to other beds. If you’re looking for another innerspring luxury bed, the closest in feel might be the Beautyrest black mattress, which contains both pocketed coil technology and luxury comfort foam, providing a medium-level firmness feel. You’ll also find similar price tags between these two mattresses. For something a little more affordable, consider The WinkBed, which has a double coil construction that helps create a solid support system that responds to your body as you adjust your sleeping position. The DreamCloud mattress might also feel similar, which has both foam and wrapped coil components to provide a firm innerspring lift and plenty of comfy pressure relief. Lastly, if you’re looking for the feel of an innerspring mattress but are interested in memory foam (for more body contouring) then you might be a good match for Tomorrow Sleep, which is a hybrid bed with a memory foam comfort layer. If you want an Aireloom memory foam option, then stick with the Bel Air Karpen Luxury mattress.Aireloom Karpen Luxury vs. Others
