Money Well Spent
Style: Level 1 Firm 12.5"
Size: Full
It’s a great mattress with lovely finish, extremely comfortable. I’m definitely happy with this investment. The "bonus": the nicest, most efficient two men delivery crew. I don’t know their names, but really appreciate not only the superb working ethics, but also most cordial, positive attitude that brightened our entire weekend. Thank you! I hope you get a good bonus, too!

Comfortable, Supportive, and Be Ready for Delivery Day
Style: Level 1 Firm 12.5"
Size: Queen
This mattress doesn’t mess around. It shows up full size, not rolled up in a box, which means no waiting for it to puff up. The upside is you can sleep on it the same night. The downside is that it’s huge and heavy, so if you live in a small apartment, be ready to use it right away or it’s going to take over the room until you do. As for comfort, it delivers exactly what I wanted in a firm mattress. The hybrid design has enough cushion to avoid feeling like a slab, but plenty of support for the back. I wake up without the aches I used to get, and it feels consistent from edge to edge. Cooling is solid too; I've had no problem with overheating, even in the middle of summer. The finish looks high quality, with nice details like side handles that actually make sense on something this heavy. Between the build, the support, and the fact that it’s ready to use immediately, it feels like a smart investment. If you like a firm mattress that gives you real support without sacrificing comfort, this one’s easy to recommend. Now if only it came with two strong guys to move it around the apartment.

Great quality, actually firm
Style: Level 1 Firm 12.5"
Size: Queen
This Serta Perfect Sleeper X Aspen 12.5" firm mattress is really nice. I really love the dark pattern, the textured material is very durable, it doesn't stain easily and it's very easy to clean. I usually get full memory foam mattresses so this is my first time trying a hybrid and the firm level is actually firm. It's very firm but not too hard and it does a great job contouring to my body shape without the feeling of sinking into the bed. It has nice edge support and it doesn't move a lot when someone is sleeping next to you. I have kids and pets so I always use a waterproof mattress cover so I don't feel any cooling effect which was expected. The mattress is somewhat heavy and it comes fully expanded so you don't need to wait to use it. This is a great quality bed and if you're looking for a firm level mattress that's actually firm, this is a great choice.
