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. Wed Sep 23 2026

This heavy-duty box spring delivers a clean, practical design to provide a reliable foundation for your mattress setup. It features a steel interior framework that helps prevent sagging and wear over time, extending the useful life of your sleep surface. The clean-lined profile is wrapped in a fabric cover, creating a neutral backdrop that coordinates easily with your choice of bedding. It easily rests inside your existing bed frame to help distribute weight evenly across the base while minimizing motion transfer. Plus, its folding design makes it easy to move through tight hallways or store away when it's not needed.

Perfect for my 14” tall mattress that I also received from Wayfair! Previously, I ordered an extremely expensive mattress and was so disappointed with it, but already had the bedtime that needed height-so this was a perfect addition! 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

The daybed with a pop-up trundle features clean lines, attractive angles, and plenty of classic style. Crafted from kiln-dried wood, it comes in a sleek finish that blends rustic and traditional for a standout look we love. The pop-up easily stores under the bed and wheels out and up when you have overnight guests. It can also combine with the daybed, transforming this piece from two twin beds to a king. Two innerspring mattresses are included, and they're wrapped and generously padded for plenty of support whenever you need to use them.

These beds work well for guests in my extra bedroom. One of the slats broke the second time it was used but Wayfair sent a new set of slats and it has held up so far. Some of the slats are joined rather than single pieces of wood which can create a weak spot. It looks nice as a daybed.. Julie. Portland, OR. Fri Sep 25 2026

Exclusive bedCLAW Wood Side Rails are a great solution for replacing broken or missing wood rails. These wood rails are laminated with top-edge veneer banded faces. This process results in a wood rail which is much stronger than a solid wood rail. It is also more stable; a laminated rail will not warp or bow as a solid wood rail can. Wood bed rails provide that classic timeless beauty that the discriminating connoisseur of fine furniture demands. Whether building a new bed or restoring an older bed, wood bed rails provide beauty and warmth unmatched by any other rail system. The industry-standard hook plates incorporated into both ends of the rails will probably fit any headboard/footboard manufactured within the last 40 years. Please measure the distance from the two pins in your headboard/footboard to confirm that they are 2" apart from the center to determine that our rail hook plates will fit appropriately. The price is for a pair of side rails (one for each side of the bed). Wood Rails are sold in pairs only to ensure a correct fit. These are the same original factory rails that are supplied by many bed manufacturers. Please note, however, that the color shown may not match your frame exactly. These rails are 82 inches Long to fit Queen or King sized beds. (Will also fit Twin XL or Full XL, but not standard Twin or Full, please measure the length of your mattress). These rails are approx. 6-5/8 inches tall. An inside lip runs down the inside of each rail, allowing easy and secure attachment of center support systems. Please measure your current rails before ordering. These are for Standard Queen and King size beds, not "Sleigh" type beds. Queen and King sized "Sleigh" type beds tend to use rails that are for Standard Twin or Full sized beds. Installing these wooden side rails along with a matching steel center support not only protects your new wood rails from bowing and breaking but also prevents your mattress from sagging and protects your mattress warranty. You will sleep more comfortably knowing that your bed is sturdy and secure. Our WF Limited Lifetime Service Policy only covers manufacturing defects in wooden rails when subject to proper handling and normal use in conjunction with a center support system that provides continuous support. To provide continuous support, a Queen or King frame must have a rigid bridge bar with at least 3 support legs or 3 equally spaced hardwood cross-slats with a supporting center leg.
