Frequently Asked Questions
Almost certainly, yes. The Zenbivy Bed fits most standard mattresses, rectangular or tapered, in either 20" x 72" or 25" x 77". The open corners of the sheet, and adjustable straps make the sheet VERY accommodating of different size and shape mattresses. We have yet to find a mattress that is close to the right size that won't work. Tapered pads sometime leave a little extra fabric, but work just as well as rectangular. If you have a question about a specific mattress, let us know and we will check it out for you!Last updated:
"R-value" is a measurement used by many mattress manufacturers to measure the warmth of their mattress.
Most people don't realize that EN tests (temperature ratings for sleeping bags) are all based on a mattress with an R-value of 5. If you pair your EN rated bag (of any design) with a mattress of a lower R-value (the vast majority of mattresses sold have lower R-value), your bag will NOT meet its EN rating for warmth.
In the last several years "air mattresses" have made a huge resurgence, and even self-inflating pads have gone on a foam-reducing weight-diet, negatively impacting their R-value. The unfortunate result is that many people cripple their 3 season bag with a "summer" mattress of R value of 1-3. Its no wonder you see so many 15 degree "winter" bags used for 3 season use.
The industry does not care, and they will sell you any mis-matched system you are willing to buy. But Zenbivy will not offer mis-matched mattresses, or build a winter bag and market it as a 3 season bag to make up for insufficient mattress.
Here's the fact: An R-value of around 5 is a "3 season" mattress, and is what is used to generate EN ratings for bags from about 5ºF to 50ºF. The majority of mattresses that are sold are summer-only, at R values of 3 or less.
The mattress and sleeping bag are a system, and unless the R-value of your mattress is 5 or above, it will not match your EN rated sleeping bag.
So if you have a 15 degree EN bag and are still cold in 3 season conditions: check your mattress. The reason you are suffering is likely because the mattress cannot support the rating of the bag.Last updated:
The pillow design is not final. We are making pattern and quilting adjustments, and finalizing the fabric on the bladder to minimize noise.
The specs on current samples are as follows:
10”x16”x3.5" (4.9-oz; packed size: 0.5 liters), with nylon taffeta stuff sack.
Shell: 50D quilted polyester pongee (3.2-oz)
Bladder: TPU top; 75D polyester & TPU laminated bottom (1.7-oz)Last updated:
No. The "hinges" on the size of the sheet are insulated with a light 40g synthetic insulation. These elements actually do not require insulation, and the insulation is there simply to provide softness between the two layers of fabric, and a unified "feel" to the hood. Using synthetic on the hinges was not a cost-savings measure. Down is a poor choice when a very thin layer of insulation is desired, since it requires complex baffling to locate the minimal amount of down. We used synthetic in this case because it is lighter and more consistent in very-thin applications than down.Last updated:
What do I do if I am sleeping in a cabin with a traditional mattress? Use the Thermarest pad yes or no?
No. One of the most awesome benefits to quilts is that they can be used anywhere. When you are on a "regular mattress" where you don't need to worry about the quilt falling off the mattress, you simply use your quilt. The fitted-sheet in the Zenbivy Bed allows the quilt to work effectively on narrow backpacking mattresses, but on a regular mattress, just use the quilt. You will find that it is so comfortable, you will get rid of your rectangular "car camping" sleeping bag and simply use your quilt on a fat camp mattress.Last updated:
