How often should I replace my mattress?
Consider an innerspring first
Choose the right firmness
Don’t rely on names. One company’s ultraplush might be another’s supersoft. Orthopedists once recommended sleeping on an extremely firm mattress, but there’s little evidence to support that view. The best surface is purely subjective, says a spokesman for the Stanford University Center for Human Sleep Research.
A study published in 2003 in the British medical journal Lancet suggested that people who suffer from lower back pain would benefit from a medium-firm mattress. That made sense to several experts we interviewed. If a mattress is too firm, it won’t support the body evenly and may cause discomfort at the heaviest points (hips and shoulders). If it’s too soft, a sleeper could sink into the surface and have a hard time moving, which could cause tingling, numbness, or aches.
Alan Hedge, Ph.D., professor of ergonomics at Cornell University, noted that the best mattress supports the spine at all points while allowing it to maintain its natural curve. By age 40, Hedge said, skin loses elasticity and becomes more sensitive to pressure points, so a softer, more cushiony surface is more comfortable. "Slightly softer works better because there’s less compression on the skin," he said.
Do the 15-minute, in-store test
Do you need a new box spring?
Foundations don’t sell for as much as the mattress, they’re generally just a wood frame enclosing stiff wire and covered with fabric to match the mattress.
If the old box has bouncy springs instead of stiff wire, it should be replaced.
If your current foundation is only a few years old, with no rips, warps, creaks, or "give," consider using it with a new mattress. Though most respondents to our recent subscriber survey replaced their foundation with their mattress, roughly 80 percent of those who kept their old one reported that they were sleeping better after replacing just the mattress. So if your box spring isn’t broken and is still structurally sound, consider keeping it and save. However, most Mattress Manufactures will not give a warranty for a mattress only. If your new mattress is ultra thick, consider pairing it with a "low profile" foundation, 4 to 5 inches thick, to reduce height.
LEAVE THE TAG ON!
Warranties: What is covered?
Most warranties cover manufacturing defects in our mattress or foundation. Replacement of one piece does not automatically constitute replacement of the other piece. Our limited warranty is provided to the original purchaser. Trade labels and law labels must be intact to identify the product and validate our warranty. Copy of original bill of sale is needed to determine the original date of purchase. The manufacture reserves the right to substitute materials of equal quality in making the repair or replacement. There is not a guarantee that the product you receive will have the same fabric cover or construction as your current mattress or box spring, especially if the replacement is being made several years after the original purchase. (There is no guarantee the replacement product will "match" the original if you purchased a set).
Make a copy of your proof of purchase (store invoice).
What is excluded under our warranty?
Our warranty does not apply to:
Normal body impressions – Slight body impressions are to be expected with today’s bedding. Most models have various layers of foam and fiber that are expected to compact. Currently we use the following as a guideline.
- Up to and including 1 ½" as normal compaction for tight top, plush, and pillow top models.
- No compaction should occur in the foundation.
- Firmness preference of the product.
- Merchandise sold "as-is", "distressed", or "floor model/sample".
- Handles (mattress handles are not designed to support the full weight of the mattress and not all Simmons® products have handles).
- Product that is shipped outside the 50 United States
- Single-sided mattresses not used with a foundation designed for use with the single-sided mattress.
Warranty does not apply if the mattress or foundation is subjected to obvious abuse or improper care/maintenance such as, but not limited to:
- Stains or soilage
- Inadequate support from weak or improper foundation (proper performance of the Simmons® single-sided mattress depends on using a firm, supportive, rigid, non-yielding foundation)
- Improper frame (full extra long, queen, and king sizes must have a sufficient center support)
- Upholstery compaction due to insufficient turning (on two-sided models)
- Bent border wires
- Bed Bugs
- Smoke or food Smells
What to Expect From Your New Mattress
All mattresses manufactured in the U.S. are hand-assembled, resulting in no two mattresses being completely identical. There are unique characteristics to each mattress, which include but are not limited to: skipped threads, fabric scuffs, contoured seams, etc. These production characteristics in no way affect the manufacturer’s warranty or the physical performance of the mattress.
We strongly recommend the use of a mattress pad or encasement for all new mattresses to protect the surface fabric from damage, spills, and/or stains, as these will invalidate the manufacturer’s warranty.
Give it some time
It often takes up to 4 to 8 weeks for our bodies to adjust to the improved support of a new mattress. Remember, you may have been sleeping on a mattress that was gradually breaking down for years.
Provide Proper Mattress Support
A new mattress needs a strong foundation beneath it. If you did not purchase a foundation (box spring) please be advised that improper support for your new mattress will eventually cause it to sag and may invalidate your warranty. King and queen mattress sets also require a frame with middle support.
Taller and Thicker Mattreses
Today’s mattresses are built much thicker than in years past. Your new mattress set will likely be higher off the ground than your previous set and your existing sheets may not fit as well. To solve these challenges, you may need deep pocket sheets that are designed for thicker mattresses. Many headboards/footboards are height adjustable and you may wish to adjust them to accommodate the thickness of your new mattress.
New Mattress Scent
New product odors are common. Our mattresses are made and packaged in a sealed plastic bag immediately after production. When the sealed plastic bag is first opened you may notice a scent that comes from the new materials and foams. While some people find the scent unpleasant, it is not harmful and should dissipate within a few days. To help speed up the process you can air out your mattress prior to putting on your sheets.
