3. Mattress Firmness – What’s the Ideal Firmness For You?

Choosing the right firmness is key to comfort and spinal support.

The newly bought mattress should align with your body type, sleep position, pain areas and pressure relief needs—without feeling too soft or too firm.

• Side Sleepers – Soft to medium firmness (great pressure relief)
• Back Sleepers – Medium to firm (good spinal alignment)
• Stomach Sleepers – Firm (prevents sinking)
• Best Mattress for Lower Back Pain – Medium-firm for optimal support

Understanding 1-10 Firmness Scale

Mattress brands rate the manufactured mattresses on a 1 to 10 scale, where 1 is ultra-soft, and 10 is rock-hard.

As far as our knowledge goes, most sleepers prefer a mattress between 3 and 8, but the right firmness depends on your sleeping position, and comfort preference.

Choose a mattress that’s ideal for you through this mattress firmness scale.

• 1-2 (Extra Soft): Deep sink-in feel, best for very lightweight side sleepers.
• 3-4 (Soft): Plush and contouring, great for side sleepers needing pressure relief.
• 5-6 (Medium): The most popular range, balancing comfort and support for combo sleepers.
• 7-8 (Firm): Less sink-in, great for back and stomach sleepers, and those with back pain.
• 9-10 (Extra Firm): Very rigid, ideal for heavy sleepers needing max support.

Here’s a quick tabular guide for mattress shopping.

Final Tips for Mattress Shopping

Buying a mattress is a long-term investment in your sleep health, and getting it right can mean years of restful nights.

But with so many options out there, how do you make the best choice?

Read our expert-backed tips to ensure you get the best mattress for yourself and your family.

1. Test It Out First

Risk-Free Trials are a Must

The first thing you should do is keep the Trial Period and return policy in mind; test out your mattress. Most top brands like Purple, Puffy, and Helix Sleep offer risk-free trials of 100 nights.

It gives you plenty of time to sleep on the mattress and decide if it’s the right fit. If it’s not? Opt for hassle-free returns to make it easy to swap for another option.

2. Check Warranty & Return Policies

Protect Your Purchase

A good mattress should last 7-10 years, and a solid warranty (10 years or so) ensures you’re covered in case of defects.

We recommend you look for mattress brands that offer:

• Long term warranties – seek 10 years or more of lifetime warranty for your mattress
• Easy return policies – especially for online brands
• Full vs. prorated warranties – Full replacements are always better than partial refunds

3. Compare Prices & Reviews

Look for Ongoing Sales

Price alone doesn’t tell the full story when you’re out mattress shopping—customer reviews, durability, and sleep quality matter just as much.

Before buying, use our Find Your Mattress tool to,

• Compare features of leading brands like Saatva, Tempur-Pedic, and Beautyrest
• Read real user reviews for insights into comfort & durability
