SpringAir is an American mattress manufacturer that has been producing high quality sleep products for over 50 years. They're known in the industry for having luxury models at less-than-luxury prices. The Isabel Firm Double Sided is part of their BackSupporter series.

The Isabel uses a 700-Count individually-wrapped pocket coil back supporter spring unit that is foam encased with a high densisty wall of foam. This is surrounded on both sides by multiple layers of foam and gel foam, including a Comfort Bridge layer to hold it all together and further reduce motion transfer. The icing on the cake is the tight quilted cover made of phase change fabric to adjust to your body temp without getting too hot or too cold.

The overall feel level of this mattress falls into the medium-firm category so it's going to provide lots of support but it will have enough cushion on top for those who sleep on their sides and need a bed to bend around their hips and shoulders.

Expert Review:
Isabel Firm Double Sided BackSupporter Mattress

The Spring Air Isabel Firm Double Sided mattress is a high-quality sleep solution for those looking for a supportive and comfortable sleeping surface with just the right amount of cushion.

At the heart of the Isabel Firm is a 700-count individually-wrapped pocket coil zoned back supporter spring unit. This provides the mattress with a strong and supportive core, with targeted support in the lumbar area, making it an excellent choice for individuals of all sizes. Additionally, the coils are foam encased, which helps to reduce motion transfer and prevent sleepers from rolling off the edge of the bed.

The feel of the Isabel Firm is a medium-firm, making it an excellent choice for those who need a supportive bed but still want to maintain a slightly soft sleep surface. This makes it a great for those who sometimes sleep on their sides, as it helps to reduce the pressure on your hips and shoulders, but also like to sleep on their back or stomach.

SpringAir has also taken all these comfortable layers and doubled them! You can flip this model over to use both sides. A combination of flipping and rotating will greatly increase the life span of your mattress. They have even included handles on the sides to make the process easier for you.

With over 50 years of experience in the industry, Spring Air has a reputation for producing luxurious sleep products at an affordable price. Their expertise even allows them to custom build this mattress in any size so it can be used on antique beds, old beautiful waterbed frames, and imported European and Asian bed frames.

Measure all 4 sides of your mattress and bed frame before ordering.
We recommend you order the mattress 1 inch smaller than the space it is meant to fill. This will leave extra room for sheets, blankets, and variations in production size. Some people like a larger gap to really have room for your hands to reach down and change sheets easily. Please note that production size is not guaranteed to be exact.


Common Questions About Ordering Custom Size Mattresses

What if it doesn't fit?
We will never ship out a custom mattress or boxspring that exceeds the size you have ordered without contacting you first to check if the size variance will cause an issue. Since these are custom made for you, they can not be returned, so please be careful when taking measurements. On some bed sets, the box spring will be a different size than the mattress so you will need to measure both pieces. Also, since beds are often set up not perfectly square, you will need to measure all four sides of the bed to find the correct size. Be sure to check in the corners for boards or bolts that often protrude in to the mattress area, and order your custom mattress and custom boxspring small enough to fit inside of these protrusions.
What sizes are available?
Any custom size is available upon request but with most models you are limited to being smaller than a King mattress. If you need a custom size bigger than a King, here are some models that can be supersized. If you don't see your size listed, please call us to find out what prices would be.
Can I really order any size and shape?
Yes, we are able to make some of our models in odd shapes (like cut or rounded corners) for antique beds, RVs, and even boats; however most of them can only be done in a 4-sided rectangle. Here is a model that can be made in any shape. You can call us to order by phone, or just select your approximate size, place the order online, and we will definitely give you a call back to discuss you exact shape before we start building anything.
We recommend you order your custom mattress 1-2 inches smaller than the space it is meant to fill. This will provide extra room for tucking in sheets and blankets.
Our online shopping lets you select a model to the nearest inch but most of the time we can even do half-inch increments for a perfect fit. We call ALL of our online buyers before we start building anything. This allows us to discuss your exact size and make changes before production begins. This lets you buy online now without fear of getting the wrong size.
What about the boxspring ?
It is very important to measure the size of your box separate from your mattress because in many older bed sets, the box was made slightly smaller than the mattress. The length and width of a solid foundation boxspring can be custom made to fit exact dimensions. The thickness can not be customized but boxes are available in several standard thicknesses ranging from 2-9 inches.
How soon will my custom size mattress arrive?
Once your order is paid for, a specialist from Michigan Discount Mattress will call you on the phone to verify your sizes and delivery information. Production will then begin and usually takes 1-3 weeks. After production, the custom mattress will be packaged at the warehouse to protect it during shipping to your home. Shipping takes 2-10 days depending on the destination city. The combination of producing, packing, and delivering means that you should receive your custom mattress within 2-6 weeks of the day you order. If you need a more accurate estimate, or have a quicker deadline, please give us a call to discuss expediting options.
