FAQs
When should you replace your mattress?
The Sleep Foundation recommends replacing your mattress if one or more of the following apply:
• Your mattress is 6-8+ years old
• It's negatively affecting your sleep
• In certain areas, it’s noticeably saggy or damaged
• It’s making more noise than usual (noisy springs are common in old innerspring mattresses)
• You find that you sleep better at hotels, friends’ houses, etc.
• You notice an increase in allergies and/or asthma
• You regularly wake up with muscle or joint stiffness
These are, of course, general guidelines but essentially, you should replace your mattress if it's no longer helping you have a comfortable and restful night's sleep.
To improve how you sleep, you may also want to invest in a good-quality mattress topper as well as decent pillows to ensure you're as comfortable as can be as you drift off.
If a bad neck is one of the reasons you feel like you're always waking up less rested than before your head hit the hay, you can get pillows for neck pain to reduce the morning aches and pains.
When is the best time to buy a mattress?
Buying a new mattress isn't something you should put off. Over time, mattresses can show signs of wear and tear, including sagging, lumps, or indentations. These issues can affect the support and comfort the mattress provides, leading to discomfort during sleep. However, the best time, in our opinion, to buy most things is during a sale event.
How long should a mattress last?
On average, a mattress should last between seven and 10 years. However, if you invest in a quality mattress, there's no reason why, with some TLC, your mattress couldn't last for much longer than that. So it's really important that when you're looking for the best mattress deals you look for quality as well as a good price.
