The FROLI® foundation forms a level air-flow surface on which to rest the mattress or cushions. The springs sit independently on the clipped-together base grid. This independent suspension adds support as the springs flex individually and adapt to your body weight and movements.
The flexing movements and the air space between the springs create an articulating air-flow surface. Your body is cushioned, yet comfortably supported.
This effect is superior to any traditional mattress/box-spring combination. Our articulating air-flow surface, combined with a good quality foam mattress, helps prevent any uncomfortable pressure points and you enjoy a relaxing and recuperating sleep, night after night.
While all FROLI® Systems are of the same high quality materials and let you customize your comfort there are some design differences that can help determine which model will be best for you:
Height helps determine the range of up-and-down flex. This, in turn, translates into comfort, a spring with more flexing will adapt better to your body and generally feel softer.
Our Travel model is the lowest in height and feels sightly firmer. The 3/8" extra height of the Star model achieves more up-and-down flex for a more cushiony feel.
The spring design of the Travel and Star is very similar.
Our Zona model is the tallest and also has a different "baffle-type" spring design. It can be precisely tuned from soft to very firm. Becasue of its height it is generally more suitable for home beds.
The surface area of the springs vary slightly in size. A smaller surface area will require more springs over any given bed area. The Travel spring is slightly larger than the Star so it requires fewer springs to cover the same space. In turn, the larger amount of Star springs needed to cover the same space will give you more points of support, making it more cushiony versus the Travel.
The Travel and Star models share a similar spreading design. As pressure is applied to the top of the spring it gives way by spreading out, similar to the way flower petals are opening up. Our Zona model uses a different, baffle type, spring design with two chambers. On top of the baffle spring sits a firm top plate. The baffle spring flexes up and down while the top plate is allowed to pivot as it adapts to body weight and movements.
Things to consider:
• Odd bed shapes
If yours is an odd-shaped bed, such as a v-berth on a boat or a "kite shaped" bed, maybe a pullman bed with a curved side, not to worry.
The Travel model was designed to accommodate any bed shapes. Springs are available in regular and small sizes that work with angles and curves. Plus, the base element lets you place the springs in a slightly diagonal setting, which works very conform along the edges.
• Condensation Issues
There is nothing better than having a permanent air space underneath the mattress for optimal air circulation. The Froli spring foundation provides continuous ventilation to help keep the mattress dry. Choose any Froli model and your moisture problem will soon be a thing of the past.
• The Uncomfortable Bed
Good news! Froli springs are designed for comfort. The foundation forms an articulated air-flow surface with each spring adapting to your body shape and movements. With each package you'll receive springs in diferent firmnesses and the set-up allows for a variety of comfort adjustments.
Note that the variation in spring height means differences in up-and-down flex. So, if you are looking for comfort, choose the taller model, Froli Star of Froli Zona.
Our Travel model has the lowest installed height of 1 3/8" = 33 mm.
The Star model installs a little taller at 1 3/4" = 43 mm.
The Zona model uses baffle type springs and is the tallest with an installed height of 2 3/8" = 60 mm.
For ease of ordering, we have created standard kits to fit most common bed sizes. We usually start out with one basic "Bed in the Box" kit (usually 2 of these make a queen bed) and add Expansion Packs (12 or 6 pcs. kits) or single elements to match the bed size.
We will be happy to determine your requirements and provide guidance for choosing the product that's right for you. You may also describe the shape of your bed and submit the details via our contact page and we will get in touch with you. Or just call us at 888-463-7654 or 843-972-9500.
You may also download a template and draw in your bed size and shape. Then, count the quantity of springs needed to fit your space and combine kits to achieve the required number of springs. Remember to use the dimensions from the bottom of your mattress since they might be different than the mattress top, i.e. some boat beds have beveled side walls.
Our springs are made of a thermoplastic elastomer, a hi-tech material with a memory effect that allows for precise flexing under load while returning to its original shape at rest.
This fancy plastic combines the flexibility of rubber with the strength of thermoplastics. Parts can flex in multiple directions, cycle after cycle, long after rubber would break.
FROLI Systems have been around since the mid-90s and easily last 10+ years. All FROLI products meet the stringent safety testing requirements by the LGA Institute of Nuremberg, Germany and have been awarded the GS certificate for product safety.
The light blue or light grey springs (depending on version) are softer and we recommended placing these in the shoulder area (rows 3 and 4 from the top). This allows the shoulder to sink in deeper, which helps achieve a better spinal alignment, particularly for side sleepers.
They are perfect for adding lumbar support. These red cloverleaf like clips increase the firmness of regular sized, dark blue/ dark grey spring elements. We include a select quantity of clips with all kits (except ½ size FROLI Travel Expansion Packs, where they would not fit the spring).
Our Zona system uses red inserts that fit sideways into the baffles of the spring to increase the firmness. one or two can be used per spring.
These clips or inserts are an additional feature to help customize your comfort. You might be perfectly comfortable without adding them, however.
Because our systems are modular they can be fitted into virtually any shape or size.
That said, our FROLI Travel model works especially well with non-traditional bed shapes, including v-berths on boats, and angled or curved shapes.
With Froli Travel, you have the option of smaller spring sizes in addition to the regular, square spring elements, for precisely fitting the system into any shape.
No, that is usually not necessary. The base elements with their attached springs are simply placed in "floating" fashion as a foundation under the cushion or mattress. It is not necessary to permanently attach the FROLI springs to the base surface.
This is not a problem. The grid of base elements does not need to be clipped together over the entire bed area. Separate sections may be created for easy removal and convenient access to storage lockers. Sometimes it’s useful to screw or Velcro the springs to locker lids for easy access, just lift the lid with springs attached!
Yes, the FROLI Sleep System forms a support base that is simply placed underneath your existing cushions or mattress, similarly to a box-spring foundation.
The FROLI works great with a foam mattress with a minimum thickness of 3-4 inches, up to 6-7 inches. Many customers use a 3” standard foam with 2” Memory Foam or Latex topper. It also works great with mattresses entirely of Latex.
We recommend medium firm foam according to your personal preference. Foam made for seating areas, could be too firm. While it might be fine for short naps it will likely be too firm to comfortably adapt to the sleeping body for extended periods of time.
Pay attention to the density of the foam. This means the weight, not the firmness. Heavier, higher density, foam means more material, less air. It will be more durable and longer lasting.
FROLI Sleep Systems are designed for use with any foam, memory foam combinations, or latex mattresses. FROLI elements underneath a heavy innerspring mattress will aid in moisture mitigation and will function as a box-spring but may offer reduced "feel" of the cushioning support because of the existing mattress' springs.
