How long is the Amazon Spring Deal Days sale?
Amazon Spring Deal Days will run from Tuesday 25th March to Monday 31st March. In 2023, the Amazon Spring Sale was three days long, but this was upped to five days for 2024. The trend continues with five days of epic deals to take advantage of.
What's the difference between Amazon Spring Sale and Prime Day?
Amazon Spring Deal Days and Amazon Prime Day are both major sales events, but they differ in timing and access. Spring Deal Days are held in March and offer discounts across various categories. The savings are open to all Amazon customers, not just Prime members. Prime Day is usually held in July, with occasional autumn events, too. These deals are exclusive to Prime members and often feature bigger discounts and limited-time offers, particularly on Amazon devices and services.
Do I need Amazon Prime to take part in Amazon Spring Sale?
Unlike other Amazon Prime Day shopping events, you don't need an Amazon Prime membership to take advantage of the discounts during the Amazon Spring Deal Days. That being said, we have seen in previous years that there are some deals on offer during the Amazon Spring Sale that are exclusively for Prime Members. You also get next-day delivery included with a Prime membership, so you can get your bargains delivered to your door as soon as possible.
An Amazon Prime Membership costs £8.99 a month or £95 for a year when you pay upfront. If you've never been an Amazon Prime member, though, you can sign up for a 30-day free trial to make the most of all the deals available. Just remember to cancel before the 30 days are up to avoid being charged.
Mattress 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.
