The Oversized Bed Buying Guide

Before choosing a bed size, measure your bedroom carefully. You need at least 60–90 cm (2–3 feet) of clearance on each side of the bed for comfortable movement, and enough space for bedroom furniture. A Wyoming King (213 × 213 cm) fits comfortably in a room that's at least 4 × 4 meters. An Alaskan King (274 × 274 cm) needs at least 4.6 × 4.6 meters. Don't forget to measure doorways, hallways, and staircases — this is where modular beds like FAMBED® have a massive advantage, as they're delivered in sections that fit through any standard door.

There are three main types of oversized beds: foam mattresses (like Big Mattress Co.), hybrid mattresses (like Engineered Sleep), and continental bed systems (like FAMBED®). Foam mattresses are the most affordable but can trap heat and lack long-term support. Hybrid mattresses combine foam and coils for better support but are heavier and more expensive. Continental bed systems — the European standard — include a base, a spring mattress, and a top mattress, offering the best combination of support, comfort, and durability. For families with young children, a firm continental system is also the safest option for co-sleeping.

This is where many oversized bed purchases go wrong. A one-piece 108-inch mattress weighs 100–200+ pounds and may not fit through standard doorways (which are typically 80 cm / 32 inches wide). Some brands require crane delivery through windows for upper floors. Modular beds solve this problem entirely — FAMBED® delivers each component separately, and the widest piece is a standard single-bed-width mattress. Assembly takes about 30 minutes and requires no tools. Always ask the brand about their delivery method before purchasing.

Most oversized bed brands are US-based and only ship domestically. If you're in Europe, Asia, or elsewhere, your options are significantly more limited. FAMBED® is the only brand we've found that explicitly offers worldwide shipping with a complete bed system. European alternatives like RIMA and ekomia offer bed frames (without mattresses) that ship throughout Europe. For US buyers, the full range of brands is available, but prices are generally higher than the European alternatives.

The advertised price of an oversized bed is rarely the full cost. Most US brands sell only the mattress — you'll still need a bed frame ($500–$2,000), oversized sheets ($100–$400 per set), an oversized duvet ($200–$500), and possibly a custom headboard. A complete setup from a US brand can easily exceed $5,000–$15,000. FAMBED® includes the complete bed system (base, spring mattress, and top mattress) in their price, and they also sell matching sheets and duvets, making the total cost much more predictable.

If you're buying a family bed for co-sleeping with children, safety is paramount. Look for firm mattresses (not ultra-plush), no gaps between mattress sections, and a design that prevents children from falling off the edges. FAMBED®'s continuous top mattress eliminates dangerous gaps, and their continental design provides the firm, flat surface recommended by sleep safety experts. Also check the warranty and return policy — a 60-day trial period (like FAMBED® offers) gives you time to ensure the bed works for your family.
