Love this memory foam mattress from Wayfair! It was easy to order and shipping was quick. It came in a box to just open and let the mattress come up to size. It is so comfortable, great for my bad back. Janice. Lenexa, KS. Mon Oct 26 2026

I was previously unaware of the concept of a mattress in a box. Upon visiting the Wayfair store, I had the opportunity to examine the mattress, having seen it advertised online. We proceeded to order it through the website due to the complimentary delivery service. It subsequently arrived packaged within a box. ItIt was quite heavy, so you will require assistance from another person to move it to its intended location. We have unraveled it, and as less than 24 hours have passed since then, this is its current appearance. Therefore, I will likely wait another 24 hours before placing it on the bed to ensure it has reached its maximum fullness. However, considering the price, we are quite satisfied with the purchase so far, and I will likely provide a follow-up review later.. Sabrina. Atlanta, GA. Sat Sep 12 2026

I loved that I received the item within 24 hours. Unfortunately, upon receipt of the item, the bottom of the box was opened. Also the mattress is not cut true to size.

[This review was collected as part of a promotion.] The quality of this mattress is excellent. It is a heavy, thick mattress with a soft and durable cooling cover. It feels like a mattress that will stand up to the test of time. I’ve had a few budget memory foam mattresses, and there is a marked difference in quality between those mattresses and this mattress. This mattress is soft, but it is definitely not plush. I would say it is medium firmness. When you lay on the mattress, it sinks in, but you do not melt into it. There is little to no motion transfer, so you do not feel your partner moving through the night. I love that there is a 100 night trial so you can shop with confidence.. Aprilb. Thu Feb 19 2026
