Not every sleep comfort purchase belongs in the same part of your routine. You may be looking for a replacement part for a Sleep Number Select Comfort mattress, or you may be shopping for something soft to wear while you sleep. The Sleep Number Select Comfort Mattress Retainer Bar Hardware Set of 2 and the Dream Products Sleep Bra Sz 44 White Comfort Soft Wireless Support Nightwear #3 sit at opposite ends of the sleep comfort category, yet they share a similar price range. This comparison is about matching the right one to the sleep comfort need you actually have.
Quick verdict
If your need is mattress-side, the Sleep Number Retainer Bar Hardware Set is the direct pick because it's made for a Sleep Number Select Comfort bed. If your need is wardrobe-side, the Dream Products Sleep Bra is the pick for a soft, wireless night layer, and it is the lower-priced option. The two prices sit $2.75 apart. Since the products don't do the same job, the decision is less about which is better and more about which sleep comfort gap you're filling.

Product notes
Sleep Number Select Comfort Mattress Retainer Bar Hardware Set of 2
This set is for the person fixing or setting up a Sleep Number Select Comfort mattress. As the higher-priced of the two, it comes as a pair of retainer bars in Full XL. The strongest argument for it is that it's the mattress-focused product here: it points directly to the Sleep Number Select Comfort system, and its type is Adjustable Air Bed. The trade-off is the used condition, so it doesn't carry the fresh-condition advantage of the bra. And because it's hardware, it only helps people who actually need retainer bar parts for this style of bed. If your sleep comfort issue is about what to wear, this set won't solve it.
Dream Products Sleep Bra
As the lower-priced pick, this sleep bra is the only product here aimed at nighttime apparel. It comes down to softness: wireless construction, a polyester/nylon/spandex blend, adjustable straps, and a hook-and-eye closure. It's new with tags and machine washable, which makes care simple. The reason to choose it is comfort-focused: a soft white bra made specifically for sleep and loungewear. The catch is the sizing: a 44 band with a one-size cup is a particular fit, so it works best for people who match that specification. It won't help with a mattress setup, but it can help make the time before bed more comfortable.
Final choice by use case
Choose the Sleep Number Select Comfort Mattress Retainer Bar Hardware Set of 2 for a mattress-support task. It's the used set at $13.99 and makes a direct match for the Select Comfort system. Choose the Dream Products Sleep Bra for sleepwear. It's the new $11.24 bra, built for soft, wireless support. When the need is clear, the decision is simple: hardware for the bed, softness for you.
