What Happened During Several Live Chat Sessions
After speaking with Sleep Number Customer Service representatives, I learned about a few extra details that may help people decide between a P-5 or an I-LE mattress.
- Mattress Top: The mattress tops are both pillowtops but they have different styles and can be accessed in the mattress differently. The European-style of the P-5 is less tall and has a smaller pillowtop than the I-LE that can be accessed from one zipper in the mattress where people can get to all the components. The I-LE has a larger pillowtop and its own zipped up portion of the mattress (for two zippers total), according to Customer Service.
- Popularity: The P-5 model is Sleep Number’s most popular bed, and the salesperson I spoke to at a Sleep Number store said it had a good balance between cushion and natural firmness from the air chambers.
- Firmness: The I-LE has more layers, so it may come as no surprise that it is the least firm of both mattresses. While P-5 is very popular, the Customer Service representative told me that, people who “love the cloud-feel or softer mattresses ” will generally get the I-LE because of its duvet-style pillowtop.

Which Should People Pick?
P-5 if…
- Someone is a Side Sleeper. Customer Service representatives told me that the P-5 would be a better choice than the I-LE for side sleepers because the 2” PlushFit comfort foam layers contains five zones for body contouring and pressure relief – including the hip area. She said: If people want to feel the pressure point relief in targeted areas of their body to ensure that they’re properly supported throughout the night, I would strongly recommend the p5 for them.
- People Want To Save Some Cash. There is a $2,800 price difference between Queen size P-5 and I-LE mattresses. Deciding on the P-5 means people will not get the soft duvet-style pillowtop or a 3” enhanced foam comfort layer with breathability, but it does make it easier to consider accessories like Sleep IQ Technology or the FlexFit Adjustable Base.
I-LE if…
- People Are Hot Sleepers. The 3” exclusive comfort foam layer in the I-LE is designed for airflow and breathability, making it a cooler mattress than the P-5, which has no cooling technology. The I-LE has cooling built into the comfort layer and not the mattress top like the I-8 model or I-10 model.
- People Like Cushioning. The I-LE is a better fit for those who aren’t interested in a naturally firm mattress. People can still adjust their level of support with their Sleep Number setting, but the I-LE’s 3” foam comfort layer and tall, soft duvet-style pillow top will keep people nicely cushioned while they sleep, as compared to the P-5.

Personal Opinion
If people choose the bestselling P-5 mattress over the I-LE model, they will save about $2,800 on a Queen size bed. They could actually purchase two Sleep Number beds for the price of the I-LE mattress.
Here is what people get for the price difference:
- Sleep IQ Technology
- 2” foam base pad
- 3” Exclusive Comfort Layer – foam layer with breathability to keep people cool
- Duvet-style luxurious pillowtop
- 3” more inches of mattress profile height (11″ vs 14″)
The P-5 mattress may be a better choice over the I-LE model for not only the cost savings, but because people get a foam layer that comes with 5 areas of pressure relief and body contouring.
As someone who sleeps on their side frequently, it’s nice to have added pressure relief in that area, even if there is 1” less of foam thickness than people would get with the I-LE.
Overall, there is a reason why people like the P-5 model, namely that it is a good mix of Sleep Number features and provides a balance of cushion and firmness.
