The 4Sleep mattress was launched in 2015 and is an all-foam mattress with a memory foam comfort layer.
Some of the key strengths of the 4Sleep mattress include:
- Competitive pricing: all sizes of the 4Sleep mattress are available for under $1000 before any coupons or promotions are applied.
- Unique cover design: the company uses a distinct weave pattern for its cover, which it also promotes as wicking to improve temperature control.
Potential drawbacks for the 4Sleep mattress include:
- Thin comfort layer: the top memory foam layer of the 4Sleep mattress is only 1.5” thick, which may reduce its ability to provide sufficient support, especially for heavier sleepers.
- Limited track record: the company has only had its mattress on the market for two years, and there are limited verified reviews that allow us to speak confidently about its performance and durability.
- Only one firmness option: the mattress is only available in a medium-firm option, so there is less ability for customers to select a firmness choice based on their personal comfort preference.

Sleep Trial / Refunds
4Sleep offers a 100 night sleep trial. During the sleep trial, you can return the mattress for a full refund, although the company requests that you try the mattress for 30 nights before initiating a return. If you choose to return the mattress, 4Sleep will arrange to have a local charity pick up the mattress. When you give the donation receipt to the company, they provide a full refund.
Be aware that terms of the sleep trial and returns may be different for mattresses purchased through a third party like Amazon. It is important to check with Amazon and/or 4Sleep to confirm these terms if you decide to buy from Amazon.
4Sleep offers free delivery within the continental United States. Once the mattress ships, it typically arrives within 2-5 business days.
Delivery does not include any installation or setup services. The mattress is delivered to your doorstep in a box. Inside the box, the mattress is compressed within plastic packaging. Once you remove this packaging, the mattress decompresses to reach its full size.
The 4Sleep mattress comes with a 10-year warranty. During this warranty period, the company will repair or replace any mattress with a defect in manufacturing or materials. Full warranty terms are available at https://support.4sleep.com/hc/en-us/articles/115002454808-Warranty.
We have limited information about 4Sleep’s customer service. Early indications are that the company works hard to support customers and to foster a positive customer experience. They also have an A+ rating from the Better Business Bureau.
The 4Sleep mattress is built with 4 distinct foam layers with a memory foam comfort layer. In general, it can be expected to share many performance characteristics with other memory foam options on the market.
Mattresses with a memory foam comfort layer typically have a good reputation for support thanks to the ability of memory foam to contour to a person’s body. However, our concern with the 4Sleep mattress is that the memory foam layer is only 1.5” thick. This thin top layer increases the risk that sleepers — especially sleepers who weigh more or who have pronounced pressure points — may “bottom out” the comfort layer and put more pressure on the supporting transition layers. Unfortunately, we have limited information from verified reviews that addresses how supportive the 4Sleep mattress has been for actual users. Until we have more data, we would urge caution with this mattress for sleepers over 230 pounds or for people with major pressure points (such as in the hips or shoulders).
The thin top layers again create potential issues when it comes to durability. While these layers have an acceptable level of foam density, more pressure and strain may be placed on the support layer and transition layers. This can threaten the long-term durability of the mattress.
The 4Sleep mattress is offered in only one firmness level. This falls between a 6-7 on the typical firmness scale. While this is the optimal firmness level for most sleepers, people who desire a very firm or very plush mattress likely would not be satisfied with the 4Sleep mattress.
A primary strength of memory foam is its motion isolation. Because it reacts only at the points where pressure is applied, motion on one part of a memory foam mattress typically does not cause motion or disruption on other parts of the mattress. For this reason, most sleepers will find that the 4Sleep mattress provides sufficient motion isolation to prevent being woken by movement of a partner or pet.
As with virtually all foam mattresses, you can expect some initial smell after unboxing a 4Sleep mattress. This smell is not harmful and typically dissipates within a few hours or a few days.
The 4Sleep mattress does not permit as much “sink” as traditional memory foam, and this helps to reduce the amount of heat retention that builds up around the body while sleeping. While extremely temperature-sensitive customers may want to avoid memory foam, most people are unlikely to experience significant issues with sleeping hot on the 4Sleep mattress.
Many memory foam mattresses can inhibit sexual activity because people may feel as though they sink into and become stuck in the mattress. The 4Sleep mattress, though, is built with a more resilient variation of memory foam that should permit greater movement on the bed. Still, shoppers who place a premium on having a mattress that is optimal for sex are likely to prefer an all-latex mattress.
