I've been to another store and they said they had a 660-coil mattress that is cheaper than yours. I thought yours were supposed to cost less?

The innerspring makes up only one part of mattress quality. Two ways to make a mattress less expensive are to use a cheaper insulator pad and low-density foam. These materials will result in a faster mattress breakdown. Also, often the innerspring used is different from the one that we use. For example, a 312 coil, 13 1/2 gauge innerspring is much cheaper (and much less supportive) than a 312 coil, 13 gauge innerspring.

Unfortunately, comparing mattresses is very difficult. The big companies even make it tough to compare the same model in different stores. However, when comparing apples to apples our mattresses always cost between 25% and 50% less.

I thought the firmest mattress would be the most expensive. Why isn't it?

Actually, the softer models usually cost more than firm models of the same quality. The answer lies in the amount of material used in the production of each. A firm mattress does not call for a lot of padding on top of the supportive innerspring, but more padding is required to create the plusher feel you get with a softer mattress. You can see the difference in the thickness of each.

Are your mattresses in stock?

We keep most mattresses in stock, and those that are not can typically be made within a day or two.

I have a narrow staircase. Is there any way to get a queen-size box spring upstairs?

We make a two-piece queen-size (and full-size) box spring for narrow staircases. We also make a hinged mattress which folds for tight areas.

Can I use my old box spring?

If the box spring is in good condition, it may not need changing. However, a box spring over ten years old should be replaced. The most important thing to stress is that an old worn out box spring will cause a new mattress to wear out much faster than normal.

What is the difference between a prorated and a non-prorated warranty?

Most major brands today have a prorated mattress warranty. Basically, the value of a prorated warranty decreases over time. For example, should you have a problem in the seventh year of a ten-year prorated warranty, only 30% of the repair would be covered. A non-prorated warranty, like we have at Portland Mattress Makers, covers the entire mattress for the length of the warranty.

What is coil count, and how does it affect the quality of a mattress?

Coil count refers to the number of coils in the innerspring of a mattress and should always be based on a full-sized mattress. While the number of coils is very important to the quality and support of a mattress, equally important is the thickness of the wire (gauge) used in the innerspring and also the number of turns in each coil.
