The Essentials
What Really Matters
Firmness
The table shows each product's verified firmness label; it does not convert that label into a guessed comfort score.
Construction
Pocket springs, memory foam, gel foam and other documented comfort materials appear in the key-features row.
Price and terms
Use the verified size prices, trial and warranty fields to compare practical differences.
Buying Advice
How to Choose a Mattress for Side Sleepers
About the selection
These products are included because they are currently tagged in the My Ideal Mattress catalogue for side sleepers. The table itself remains specification-led and does not declare a universal winner.
Our Tip
Missing information is deliberately left blank in the comparison table rather than estimated.
Checklist
Before You Buy
Check the current price for your exact mattress size
Read the full sleep-trial and warranty terms
Confirm delivery, collection and recycling arrangements
Use the manufacturer or retailer product page for any specification not shown in the table
Questions
Frequently Asked Questions
No. Body weight, shoulder and hip pressure, preferred firmness and temperature can all affect comfort.
