I feel the description did not thoroughly explain that the second mattress was not able to put underneath the daybed. It’s so inconvenience to remove the second mattress and put them back every time you wanna change it into a king bed. I wish it was thoroughly explained. I would not have bought this bed if I knew that you have to remove the mattress every single when your guests leave.. Anonymous. Tue Nov 04 2025

The integrated pop-up trundle rests on smooth-rolling casters for easy movement and can be raised to create an even sleeping surface. It also features a powder-coated finish that stands up to daily use.

The bronze color is a rich matte finish brown. I am 64 yo and was able to build it by myself. It did take a while (NOT 1.5 hours for me) and as another reviewer said, pushing all those plastic pieces in was rough on the hands ! It does seem very sturdy though. Well built, not flimsy at all. Don't tighten anything at all until everything is together - leave it really loose. Had to go back and loosen at first for more flexibility in connecting. 8" mattresses coming tomorrow - $99 deal each so the whole thing will be less than $500 for my grandchildren when they visit so they no longer have to bring sleeping bags or camp out on the floor ! I'd show you after the bedding is on but I'll prob forget so here it is....for now. Wendy. Ocean, NJ. Thu Oct 15 2026

This twin daybed delivers a versatile sleeping and seating solution for your space. It's crafted from a solid rubberwood frame and features rattan webbing panels for a breezy, textured look. The included pop-up trundle wheels out on casters to easily convert the daybed into a larger sleeping surface or two separate twin beds. With its finished back, you can place it anywhere in your home. Plus, the solid wood slats provide plenty of support for your mattresses.

Very happy with this purchase! The bed is sturdy and looks great. One helpful thing to know make sure to purchase an 8-inch mattress for the bottom trundle. The listing doesn’t specify a mattress thickness, and anything thicker than 8 inches will prevent the trundle from sliding underneath the bed properly. Hopefully this helps anyone trying to figure out what size mattress to order!. Shauna Monae. Ventura, CA. Tue Sep 22 2026

Perfect for my 14” tall mattress that I also received from Wayfair!

It took 30 seconds to unfold, set in the frame, and zip up the cover. It’s super heavy duty and my heavy mattress doesn’t sag at all. I would certainly recommend this product if your mattress needs support and a little boost!. Crystal. Springfield, IL. Wed Oct 14 2026
